About the Day Rate Calculator (UK/US)

A day rate calculator helps permanent employees considering contracting understand what to charge. It converts salary to contractor day rates accounting for taxes, benefits, and overhead in both UK and US markets.

Quick Start Guide

  1. Enter your values — Fill in the fields with numbers relevant to your day rate (uk/us) calculation. Most fields include sensible defaults.
  2. Adjust settings — Change options like units, rates, or timeframes to match your specific scenario.
  3. Review results — The output shows a clear breakdown so you understand how the total was calculated.

How It Works

Contractor day rate = (desired annual income + business costs + risk premium) / billable days. Billable days typically = 220-230 (365 − weekends − holidays − vacation − sick days − training − non-billable admin).

Real-World Example

Scenario: UK permanent employee earning £65,000 considering contracting

  1. Current salary: £65,000.
  2. Total comp with benefits: ~£85,000 (employer NI + pension + benefits).
  3. Billable days: 220 per year.
  4. Day rate: £386 (break-even) to £500 (with risk premium).
Result: Break-even day rate: ~£386. Recommended rate (with risk premium): £450-500/day. At £500/day × 220 days = £110,000/year — compensating for gaps between contracts, pension, and no paid leave.

How to Use

This calculator works backward from your target income to find the day rate you need to charge. Here is what each input means:

  1. Desired Annual Salary — how much you want to take home after all expenses and taxes.
  2. Business Overhead — your total annual business costs including software, insurance, and office space.
  3. Billable Days Per Year — the number of days you can actually charge clients. Start with 260 weekdays, subtract vacation, holidays, and sick days.
  4. Non-Billable Time — the percentage of your working time spent on admin, marketing, and proposals. 20% is typical.
  5. Tax Rate — your combined tax burden. For US freelancers, 25-35% is typical.
  6. Profit Margin — a buffer for growth, savings, and unexpected costs. 10-20% is healthy.

Day Rate Formula

Revenue Needed = (Salary + Overhead) / (1 - Tax Rate)
Total Billable Days = Billable Days × (1 - Non-Billable%)
Base Day Rate = Revenue Needed / Total Billable Days
Day Rate with Profit = Base Day Rate × (1 + Profit Margin)
Hourly Rate = Day Rate with Profit / 8

Frequently Asked Questions

A typical full-time freelancer bills 180-220 days per year. The calculation starts at 260 weekdays (52 weeks x 5 days), subtracts 20-30 days for vacation and holidays, and accounts for 15-25% non-billable time.
Include all business expenses: software subscriptions, hardware depreciation, insurance, office space or coworking, internet and phone, marketing costs, professional development, and legal/accounting fees.
Taxes significantly impact your required day rate. Revenue needed = (Salary + Overhead) / (1 - Tax Rate). At a 30% tax rate, you need to earn roughly 43% more than your target income just to cover taxes.
Day rates are preferred for creative and consulting work where the output matters more than the hours. Hourly rates work better for ongoing maintenance and support. Many freelancers use both.
