Fixed-Fee Project Quote Calculator
Turn an estimated project cost into a fixed fee at your margin or markup.
In short
Turn an estimated project cost into a fixed fee at your margin or markup.
Formula: Cost with reserve = Cost × (1 + Contingency rate); Fee = Cost with reserve ÷ (1 − Margin) for a margin, or Cost with reserve × (1 + Markup) for a markup
What this calculator does
The user chooses margin or markup and the calculator applies only that method, reporting both resulting percentages so the difference is visible.
Use it to turn Currency, Estimated project cost, Contingency reserve (optional), Pricing method, and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Estimated project cost
- — number value.
- Contingency reserve (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Pricing method
- — Margin is a share of the price. Markup is an addition to cost. They are not the same number..
- Margin or markup
- — number value.
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Cost with reserve = Cost × (1 + Contingency rate); Fee = Cost with reserve ÷ (1 − Margin) for a margin, or Cost with reserve × (1 + Markup) for a markup.
Inputs used: Currency, Estimated project cost, Contingency reserve (optional), Pricing method, Margin or markup.
Edge handling: Estimated project cost is required.; Estimated project cost cannot be negative.; Estimated project cost must be no more than 1000000000000.; Contingency reserve (optional) is required.; Contingency reserve (optional) cannot be negative..
Worked example
$62,000 of cost quoted at a 25% margin
- Start with Currency: USD, Estimated project cost: 62000, Contingency reserve (optional): 8, Pricing method: margin, Margin or markup: 25.
- Apply the method: Cost with reserve = Cost × (1 + Contingency rate); Fee = Cost with reserve ÷ (1 − Margin) for a margin, or Cost with reserve × (1 + Markup) for a markup.
- The reserve is added to cost before the margin is applied.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this fixed-fee project quote calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Cost-plus pricing applied to a cost that already includes any contingency reserve, with margin and markup kept as separate methods. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
Shows the fee implied by the inputs; it does not say what a client will accept. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
How do I use the Fixed-Fee Project Quote Calculator?
Enter the required values for Currency, Estimated project cost, Contingency reserve (optional), Pricing method, Margin or markup. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Fixed-Fee Project Quote Calculator use?
Cost with reserve = Cost × (1 + Contingency rate); Fee = Cost with reserve ÷ (1 − Margin) for a margin, or Cost with reserve × (1 + Markup) for a markup The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
Can the Fixed-Fee Project Quote Calculator be used for exact decisions?

Formula, source and verification
Cost-plus pricing applied to a cost that already includes any contingency reserve, with margin and markup kept as separate methods.
The question it answers: What fixed fee should I quote for a project that costs us this much to deliver?
The formula
Cost with reserve = Cost × (1 + Contingency rate); Fee = Cost with reserve ÷ (1 − Margin) for a margin, or Cost with reserve × (1 + Markup) for a markup
- C — Estimated project cost
- (currency). Total cost of delivering the project.
- g — Contingency rate
- (%). Optional reserve added to cost before pricing.
- m — Margin
- (%). Share of the fee kept as profit.
- k — Markup
- (%). Percentage added to cost to reach the fee.
