Contractor Rate Calculator
Estimate an hourly or daily contractor rate based on your target income, business costs, taxes and billable time.
Overview
This contractor rate calculator helps you estimate the hourly and daily rate you may need to charge based on your target annual income, expected business costs, tax buffer and realistic billable time. It is useful for freelancers, consultants and self-employed contractors who want a practical starting point for pricing their work.
How it works
The calculator first estimates how much revenue you need to generate so you can cover a tax set-aside and your annual business expenses while still reaching your target income. It then divides that required annual revenue by your estimated billable days and billable hours. The result is a suggested daily rate and hourly rate based on the amount of time you expect to spend on paid client work rather than total working time.

Frequently asked questions
What does this contractor rate calculator estimate?
It estimates the hourly and daily rate you may need to charge to cover your costs and reach your target annual income.
Should I include non-billable time in this calculator?
Yes. You should reduce your billable days or hours to reflect time spent on admin, sales, proposals, training and other unpaid work.
What should I include in annual business costs?
Typical costs include software, hardware, insurance, professional memberships, accounting, marketing, travel and workspace expenses.
Why is the tax buffer separate from business costs?
Business costs are operating expenses, while the tax buffer is a percentage allowance to help you set aside part of your revenue for taxes.
Is the suggested rate the price I should always charge?
Not necessarily. It is a baseline estimate. Your final rate may also depend on experience, market demand, niche skills and project complexity.
Can I use this calculator for freelance day rates?
Yes. It works well for freelancers and consultants who quote by the hour or by the day.
