Contract Comparison Calculator

Calculate and evaluate your potential incomes from two separate contracts

You can use this calculator to compare your current contract with a new one and find out how much more pay the new contract yields.

Or if you’re considering multiple contract offers, this calculator allows you to compare potential earnings from two contracts to determine which is better paid and help you decide which contract to accept.

This calculator incorporates hourly rates, duration and IR35 status to estimate your potential earnings. The results will display the annual and monthly difference between each contract as both a cash sum and a percentage.
