Hourly to Project Rate Calculator

What this tool does

The Hourly to Project Rate Calculator converts your hourly rate into a recommended flat project rate. It factors in estimated hours, a revision buffer, and a risk buffer, then returns a base rate, a recommended rate, and a pricing range.

Flat-rate projects are appealing to clients but risky for freelancers, because scope creep and revisions quietly eat your margin. Buffers are how you price that risk in without endless renegotiation.

The result includes a low-to-high range so you can anchor your quote based on the client, the project, and your current pipeline.

How to use it

1. Enter your hourly rate and estimated hours.
2. Add a revision buffer percentage (e.g. 15% for one revision round).
3. Add a risk buffer percentage (e.g. 20% for uncertain scope).
4. Read the base rate, recommended rate, and pricing range.

How it works

• Base rate = hourly rate × estimated hours.
• Total buffered hours = estimated hours × (1 + revision buffer + risk buffer).
• Recommended rate = hourly rate × buffered hours.
• The range spans 90% of the base rate (a discount floor) to 115% of the recommended rate (a premium ceiling).

Example

Rate $90/hour, 20 hours, 15% revision buffer, 20% risk buffer → base $1,800, recommended $2,430 (27 buffered hours), range $1,620–$2,794.
