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.

build a quote that protects your margin
recommended project price$4,950
fully-loaded cost (+ buffer)$2,475
effective hourly rate$124/hr
gross profit (planned)$2,475
suggested 50% deposit$2,475
Healthy-ish (30-55%). Room to raise price or cut delivery hours.
what to do
  • A 10% hours overrun costs about $225 - your 10% buffer covers that.
  • At $4,950 you're billing 2.8x your blended cost rate.
Quoted $4,950 at 50% margin - track whether the project actually holds it, live.

the method

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.

how to use it

Five inputs, one defensible price

  1. Enter the estimated hours and your blended team cost rate.
  2. Add your overhead on labour, as a percentage.
  3. Set the gross margin you want the project to clear.
  4. Add a contingency buffer for scope creep, then read the price, margin, effective rate and a suggested deposit.

questions

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.
