Freelance Rate Calculator: Copy This Free HTML/JS Tool

Want me to review your pricing? $10 via PayPal — send me your service + target client, I'll suggest 3 rate options

This is the freelance rate calculator I actually use. Not the "charge 3x your salary" rule of thumb — a tool that converts your real costs, market rates, and project scope into a concrete number you can actually defend to clients.

How to Use This Calculator

Step 1: Enter your monthly target income (after tax)
Step 2: Enter your monthly costs (software, hardware, insurance, etc.)
Step 3: Enter estimated hours for this project
Step 4: Adjust the complexity multiplier (1.0 = simple, 2.2 = very complex)
Step 5: Read your recommended rate at the bottom

The calculator gives you three numbers:

Minimum viable rate — what you need to charge to hit your income target
Market rate — adjusted for project complexity
Ideal rate — with 20% buffer for scope creep and unexpected work

Why This Calculator Works

Most freelance rate calculators start with "charge 3x your salary." That's useless advice if:

Your salary doesn't cover your actual costs
You work fewer than 40 hours a week on billable work
Your market doesn't support 3x salary rates

This calculator starts with your actual numbers and builds a rate from there.

The Formula Behind It

Base Rate = (Monthly Target Income + Monthly Costs) / Billable Hours per Month

Market Rate = Base Rate x Complexity Multiplier

Ideal Rate = Market Rate x 1.2 (20% buffer)

Project Total = Ideal Rate x Project Hours
