Agency project quote calculator
Stop pricing projects on gut. Enter the scope and your costs, pick the margin you want to hit, and this builds the price you should quote - with a contingency buffer so scope creep doesn't eat your profit.
- A 10% hours overrun costs about $225 - your 10% buffer covers that.
- At $4,950 you're billing 2.8x your blended cost rate.
Built with Forge - done-for-you automation for agencies.
How the quote is built
price = (hours × cost × (1 + overhead) × (1 + buffer)) / (1 - target margin)
Start from the fully-loaded cost of the work, add a contingency buffer for the hours that always creep in, then mark it up so what's left after cost is exactly the margin you set. The result is a defensible price - not a round number you hoped was enough.
Five inputs, one defensible price
- Enter the estimated hours and your blended team cost rate.
- Add your overhead on labour, as a percentage.
- Set the gross margin you want the project to clear.
- Add a contingency buffer for scope creep, then read the price, margin, effective rate and a suggested deposit.

Frequently asked questions
How do I price an agency project?
Work out the fully-loaded cost (hours × blended cost rate × (1 + overhead)), add a contingency buffer, then mark it up to your target margin: price = buffered cost / (1 - margin). That's the price that clears the profit you want.
What margin should I quote a project at?
20-35% gross margin is typical for agencies; 50%+ is strong and usually comes from value-based pricing. Set the target and the calculator solves the price.
What is a contingency buffer?
A percentage added to your estimated effort to cover the hours that always creep in - revisions, edge cases, client delays. 10-20% is common; it protects your margin when the work runs long.
Should I ask for a deposit?
Yes - a 50% upfront deposit is standard for project work. It funds delivery and signals commitment. The calculator suggests the deposit from your quoted price.
