Job Pricing Calculator

Define the scope before choosing numbers

Materials is the cost of supplies and parts assigned to this job, including expected waste if your estimate requires it. Labor is the cost you choose to assign for the work, not automatically a customer hourly charge. Allocated overhead is the portion of shared business costs you want this job to recover. The calculator adds exactly these three fields; it does not infer tax, permits, freight, subcontractor cost, disposal, financing, or a contingency. Include relevant amounts within a field or handle them separately in the quote. A clear written scope matters because a mathematically correct price for an incomplete scope can still lose money.

Target margin (%) is a share of final price. Entering 25 means the modeled total cost should occupy 75% of the selling price. This differs from applying a 25% markup to cost. The markup versus margin calculator can help reconcile the two ways of describing profit. Before quoting, decide whether overhead is a fixed dollar allocation for the job or is already embedded in your labor cost. Count it once.

How the calculation works

Total cost = materials + labor + allocated overhead. Price = total cost / (1 − target margin / 100). The calculation needs all three cost amounts and a margin below 100%. It has no separate treatment for negative inputs, so use nonnegative costs for an ordinary quote. The result table shows total cost and price; it does not separately display profit, though profit is price minus total cost. Currency formatting may round the visible value, while the formula uses the exact input values.

Proposal example

Example assumptions — not benchmarks: materials $300, labor $400, allocated overhead $100, target margin 20%. Total cost is $300 + $400 + $100 = $800. Because 20% margin leaves 80% of price for cost, the needed price is $800 / 0.80 = $1,000. Modeled profit is $1,000 − $800 = $200, and $200 / $1,000 = 20%. Adding 20% to $800 would yield $960, which would not meet the entered margin target. The example is a formula check, not an estimate for a real task.

Check the labor number

For an employee job, labor cost should reflect the paid hours and employer expenses you intend to recover. A wage alone omits taxes, benefits, and insurance. The employee true cost calculator can help develop an annual employer amount, while labor rate builds an hourly selling target from wage, burden, overhead, and margin. If you use that selling rate as the Labor input here and also add overhead and margin again, you can double count those layers. Use a cost basis consistently.

Allocated overhead is also a judgment. One possible method is to spread expected monthly overhead across expected completed jobs or productive hours, then assign a share to this job. That method depends on volume actually occurring. A low-volume month makes a fixed allocation harder to recover. Test the overhead amount against monthly expense and actual throughput. The calculator cannot tell whether the customer will accept the resulting price or whether the production schedule can deliver at the planned labor cost.

Review the finished job

After completion, replace estimated costs and expected revenue with actuals in profit margin. Compare that result with the target used here. Material substitutions, extra visits, scope changes, discounts, and unbilled labor can widen the gap. Recording why the gap occurred helps the next estimate more than adjusting a generic target percentage. Use a signed change process when the scope shifts so both cost and price can be reconsidered while work is still underway.
