Day rate required to match employee comp.

An employee on 70,000 plus 10,000 in benefits, working 220 billable days as a contractor with 5,000 of annual overhead, needs at least 386 a day to match — 80,000 plus overhead divided by billable days. Below that and contracting is a pay cut, even if the day rate looks impressive.

How to use it

Enter your current total package as a permanent employee (salary plus benefits value), the number of billable days you realistically expect, and any annual business overhead (accountant, insurance, software).

What the result means

The minimum day rate is what it helps to clear to equal the employee package. Hourly equivalent divides by eight. Use this as the floor — add a margin for risk and for the fact contractors typically lose unbilled time to business development.

The math does not handle the tax efficiency sometimes available through limited company structures — in some jurisdictions that can reduce the day rate required by 10-15% versus the headline figure.

Quick example

With current gross salary of 70,000 and benefits value of 10,000 (plus billable days per year of 220 and annual business overhead of 5,000), the result is 386.36. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Current Gross Salary, Benefits Value, Billable Days Per Year, and Annual Business Overhead. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Required day rate equals total target income (salary plus benefits plus overhead) divided by expected billable days. The tool does not adjust for tax efficiency from company structures or the risk premium contractors usually add. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why small rate shifts add up

A 3% pay rise looks modest. Apply it over a 30-year career with modest promotions and the lifetime difference runs to six figures. This calculator makes that invisible compounding visible in a way spreadsheets usually don't.

What this doesn't capture

Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
