The formula should never be a secret.

True Hourly Rate Calculator

The calculator produces two benchmarks. The minimum sustainable rate covers the owner-income goal, annual overhead, and the chosen employer-tax-and-benefits reserve. The recommended rate adds a target business profit margin.

1. Available and billable hours

Billable time matters because sales, admin, scheduling, travel, training, and gaps consume working hours that cannot be invoiced directly.

2. Annual cost need

The reserve is a planning input for employer-side payroll taxes and business-funded benefits or retirement contributions beyond the pre-tax owner-income target. It is not a personal income-tax calculation, and personal tax should not be added twice. Actual obligations vary by entity type, location, and other factors.

3. Minimum sustainable rate

This is a floor based on the supplied assumptions. It includes no business profit beyond the owner-income input.

4. Profit-aware target rate

Profit is modeled as a percentage of revenue. That is different from adding the same percentage as a markup on costs. For example, a 20% margin requires dividing costs by 0.80—not multiplying them by 1.20.

How to pressure-test the result

1. Compare the billable-time assumption with recent calendar and invoice data.
2. Review at least 12 months of expenses so annual or irregular costs are not missed.
3. Check whether the owner-income figure is before or after personal tax and use it consistently.
4. Compare the calculated rate with market positioning, demand, and the value of the outcome—not only competitors' posted rates.
5. Recalculate when costs, capacity, or income goals materially change.

Project Quote Calculator

The Project Quote Calculator converts a loaded hourly rate and a realistic scope estimate into a protected fixed price. The loaded rate is assumed to already cover owner pay, overhead, reserves, non-billable business time, and normal profit.

1. Base and protected project hours

Admin time includes project-specific scoping, meetings, communication, scheduling, handoff, invoicing, and collection work. The buffer protects against ordinary estimation error within a defined scope. It does not replace revision limits or change-order terms.

2. Labor and direct-cost pricing

Direct-cost markup can compensate for sourcing, coordination, financing, transport, warranty, and replacement risk. Use 0% when a cost is genuinely passed through without added work or risk.

3. Exact and rounded quote

Upward rounding creates a clean client-facing price without quietly rounding below the protected calculation. The result excludes applicable sales tax. Upfront-cost coverage tests only entered direct costs. Labor completed before the next payment, cancellation risk, and contract requirements still belong in the payment schedule.

How to pressure-test a fixed-price quote

1. Separate delivery work from project-specific administration so neither category disappears.
2. Compare estimated hours with completed projects of similar scope.
3. Define deliverables, revision limits, client responsibilities, exclusions, and change-order triggers in writing.
4. Confirm that the loaded hourly rate already supports the business before using it inside a fixed quote.
5. Review the deposit against cash outlay, cancellation risk, and the amount of work completed before the next payment.

Margin, Markup + Target Price Calculator

This calculator compares gross profit with both the direct cost and the selling price. Margin and markup use the same gross-profit amount but divide it by different numbers, so equal percentages do not describe equal prices.

1. Gross profit per sale

Direct cost should include the labor, materials, fees, fulfillment, subcontractors, and similar costs caused by delivering one sale. Gross profit is not net business profit because overhead, owner compensation, tax, interest, and other expenses are not subtracted.

2. Gross margin and markup

For a $60 cost and $100 selling price, gross profit is $40. The gross margin is 40% because $40 is divided by $100. The markup is 66.7% because the same $40 is divided by $60.

3. Selling price for a target margin

The target margin is entered as a decimal inside the formula. For example, a 25% target margin uses 0.25 and requires a 33.3% markup. The calculator caps the target below 100% because dividing by zero cannot produce a finite price.

How to pressure-test a margin target

1. Confirm that direct labor—including owner delivery time—is not missing from cost.
2. Separate gross margin from net margin so overhead and owner pay do not disappear.
3. Compare the target price with customer value, positioning, alternatives, and demand.
4. Recalculate when supplier pricing, wages, transaction fees, or delivery time changes.
5. If the market will not support the required price, change the cost structure or offer rather than pretending the margin exists.

Discount Profit Impact Calculator

This calculator compares contribution profit before and after a proposed discount. Contribution profit is the amount left after variable costs to cover fixed costs and profit. The model holds fixed costs constant so it can isolate the economic hurdle created by the price cut.

1. Current contribution baseline

Variable cost should include the costs caused by one additional order, job, or unit. Examples include direct labor, materials, packaging, fulfillment, transaction fees, commissions, and shipping. Do not mix fixed rent or general overhead into this input.

2. Discounted unit economics

The calculator assumes variable cost per sale remains constant. If volume discounts, payment fees, overtime, waste, or fulfillment costs change under the promotion, use the expected cost for the discounted scenario.

3. Sales needed to preserve contribution

This calculation is available only when both the current and discounted contribution per sale are positive. If the discounted price is at or below variable cost, each additional sale contributes nothing or loses money. No finite volume increase can restore a previously positive contribution result.

4. Expected promotion result

Revenue and contribution can move in opposite directions. A promotion can produce more orders and higher revenue while leaving less money for fixed costs and profit.

The contribution-margin basis follows the definitions used in the U.S. Small Business Administration break-even guidance and OpenStax managerial accounting.

How to pressure-test a discount

1. Use recent sales and cost data from the same time period.
2. Estimate sales lift from comparable promotions, tests, or demand evidence—not optimism.
3. Account for full-price purchases that may be cannibalized by the discount.
4. Confirm capacity, inventory, staffing, and service quality can support the additional volume.
5. Consider whether the offer attracts repeat customers or merely trains existing customers to wait for a lower price.

Break-Even Sales Target Calculator

This calculator uses cost-volume-profit analysis to estimate the sales volume and revenue needed for one average sale to cover a consistent period of fixed costs. It then adds a target operating profit and compares both thresholds with expected sales volume.

1. Contribution per average sale

Contribution is the amount each additional sale provides toward fixed costs and operating profit. For a mixed business, the average price and variable cost must reflect the expected sales mix.

2. Break-even sales and revenue

The mathematical sales result can contain a fraction. The calculator rounds the operational target upward to the next whole sale so it does not knowingly understate the amount required. If contribution per sale is zero or negative, no finite volume can cover fixed costs.

3. Sales for a target operating profit

Break-even produces zero operating profit under the assumptions entered. Adding the profit goal distinguishes the survival threshold from the result the owner actually wants.

4. Forecast and margin of safety

A positive margin of safety shows how far expected sales sit above break-even. A negative result shows the forecasted shortfall. The model estimates operating profit, not cash availability, and does not automatically include tax, debt principal, owner distributions, customer payment delays, or capital spending.

How to pressure-test a break-even target

1. Use the same month, quarter, or other period for fixed costs and expected sales.
2. Include direct owner labor in variable cost when one more sale requires more delivery time.
3. Decide deliberately whether fixed owner compensation belongs in fixed costs.
4. Use a weighted average only when the expected sales mix is stable and representative.
5. Compare the required volume with real demand, staffing, equipment, inventory, and service capacity.

Cash Runway Calculator

This calculator estimates the first month-end when available cash reaches a protected reserve floor. It uses actual cash receipts and cash outflows rather than accrual revenue and expense because liquidity depends on when money enters and leaves the business.

1. Recurring monthly net cash flow

Cash receipts are collections expected during the month. Cash outflows should include operating payments plus other recurring uses of cash such as inventory, debt principal and interest, tax, owner draws, and capital payments when applicable. Accounting profit can differ because revenue and expense recognition may not match cash timing.

2. Usable cash above the protected reserve

The reserve floor is a decision trigger chosen by the owner. The model does not assume that spending the bank account to zero is an acceptable plan. If starting cash is already at or below the floor, runway above the reserve is zero.

3. Month-end cash projection and known events

One-time events are applied at the end of the selected month. The displayed runway is the number of complete month-ends that remain above the reserve before the first reserve month. A business with tight weekly or daily timing needs a more detailed cash forecast, because a month can contain a shortfall even when its ending balance appears safe.

4. Stress scenario

The stress case changes recurring cash movements while leaving the known one-time events unchanged. “No finite limit” means the constant scenario entered does not project a reserve breach after those events; it is not a guarantee against seasonality, late collections, growth investment, tax, inventory, debt, or omitted events.

The distinction between cash and accrual timing is consistent with the accounting-method explanation in IRS Publication 538. Cash-reserve and cash-flow planning are also covered in the FDIC Money Smart for Small Business cash-flow module.

How to pressure-test a cash runway

1. Reconcile starting cash to balances that are actually available, excluding receivables, unsigned sales, and undrawn credit.
2. Build recurring receipts from collection timing rather than sales booked, and use conservative assumptions for overdue customers.
3. Include debt principal, tax, inventory purchases, owner draws, and capital spending when they consume cash.
4. Count a one-time inflow only when its amount and timing are committed enough to plan against.
5. Turn the reserve month into action dates for pricing, collections, cost reductions, financing, or investment decisions before the floor is reached.

Can I Afford to Hire? Calculator

This calculator compares the employee's loaded cash cost with the contribution from revenue the added capacity is expected to support. It keeps recurring economics, the temporary ramp deficit, and payback separate because a hire can pass one test and fail another.

1. Loaded recurring employee cost

The employer-cost percentage is a user-entered planning assumption. The calculator does not hard-code payroll tax, unemployment, workers' compensation, insurance, or benefit rates because the applicable amounts depend on the role, location, employer, and current rules. One-time recruiting, equipment, setup, and initial training costs are added separately to first-year cash cost.

2. Revenue contribution before the hire cost

Contribution margin should subtract the materials, fulfillment, fees, commissions, shipping, and other non-employee variable costs caused by the added revenue. The new employee cost should not be included inside that margin because the calculator subtracts it separately.

3. Ramp and first-year result

The model applies one average productivity percentage during the entered ramp months and full productivity afterward. This is a planning simplification, not a prediction of a smooth learning curve or immediate customer collections.

4. Funding need and payback

Cash available above reserve is compared with the largest modeled deficit. Payback is the first month when cumulative contribution has covered the loaded and one-time costs entered. If contribution at full productivity does not exceed recurring loaded cost, the model reports no finite payback.

How to pressure-test a hiring case

1. Verify employer taxes, insurance, benefits, wage rules, and other obligations for the actual role and location.
2. Tie added revenue to constrained demand, deliverable capacity, or proven owner time that the hire will free.
3. Exclude the new employee cost from the contribution-margin input so it is not counted twice.
4. Test a slower ramp, lower contribution margin, delayed collections, and an early departure before making the offer.
5. Protect an operating reserve and use a detailed cash forecast when payroll and customer collections occur on different dates.

Equipment Investment Calculator

This calculator tests a cash equipment purchase against four separate conditions: positive monthly operating benefit, enough cash above the protected reserve, payback inside the planning horizon, and value above a user-entered required return.

1. Full upfront investment

Setup and launch costs may include delivery, installation, permits, facility changes, training, integration, testing, and initial downtime. The model treats the purchase as a cash commitment and does not estimate loan or lease payments.

2. Monthly operating benefit

Added revenue is reduced to contribution so materials, fees, fulfillment, and other non-equipment variable costs are not counted as equipment benefit. Cost savings should reflect cash costs the purchase actually removes.

3. Payback and simple return

Operating payback excludes the estimated end value so a generous resale assumption cannot manufacture a fast payback. When monthly operating benefit is zero or negative, the model reports no finite operating payback.

4. Discounted value and protected cash

Future cash flows are discounted using the equivalent monthly rate derived from the required annual return entered. Cash remaining above reserve equals available cash above reserve minus the upfront investment. A positive value case does not override a protected-cash shortfall.

Menu Item Economics Calculator

This calculator estimates item-level contribution after food, expected loss, packaging or serving supplies, percentage selling fees, and direct labor. It does not allocate restaurant fixed costs or label the result net profit.

1. Food after the loss allowance

The allowance can represent spoilage, trim loss, over-portioning, remakes, and comps when those costs are not already captured in the recipe data.

2. Fees, labor, and item contribution

Monthly contribution multiplies contribution per item by whole monthly units. It is the pool available for fixed and shared costs and profit, not a restaurant profit-and-loss result.

3. Target contribution price

Fixed item-level cost in this equation includes food after loss, supplies, and direct labor. Because percentage fees increase with price, they remain in the denominator. When fees plus the target margin reach 100%, the calculator reports no finite target price.

Price Increase Decision Calculator

This calculator compares current and proposed contribution over one consistent sales period. Existing fixed costs are held constant; only recurring period costs caused by the change are subtracted.

1. Current and proposed contribution

Proposed volume applies the entered percentage change to current whole-unit volume. The result remains a scenario, not a demand prediction.

2. Contribution-preserving sales level

The practical sales threshold rounds upward to a whole sale. When proposed contribution per sale is zero or negative, the model reports no contribution-preserving volume.

Business Loan Affordability Calculator

This calculator models a fixed-rate, fully amortizing loan with equal monthly principal-and-interest payments. It separates monthly payment coverage from cash used at closing.

1. Payment and total interest

P is financed principal, r is the monthly interest rate, and n is the number of monthly payments. A zero-interest balance is divided evenly across the term. Variable rates, balloons, and revolving credit are outside the model.

2. Base and stressed payment coverage

The coverage target is user-entered and is not represented as a lender approval standard. Cash remaining above reserve equals cash available above reserve minus cash due at closing.

Restaurant Labor Capacity Calculator

This calculator compares one restaurant schedule with sales in the same period, an owner-selected labor budget, a minimum operating coverage floor, and a weaker-sales scenario.

1. Loaded hourly and fixed labor cost

Overtime wages use the entered multiplier. The calculator does not determine which hours, employees, or wage components are legally subject to overtime.

2. Labor percentage, budget, and coverage

Stressed labor percentage holds the schedule cost constant and reduces sales by the entered percentage. A schedule below the coverage floor is flagged before any favorable budget result.
