How to work out a day rate that actually covers your year

Guessing at a day rate is how you end up underpaid

Ask most freelancers how they picked their day rate and the honest answer is some mix of "what felt fair," "what the last client paid," and "a bit more than that." None of those numbers come from anything you actually need to earn. They come from what sounded reasonable at the time, and reasonable-sounding numbers have a habit of quietly falling short.

The fix is to work backwards from the year, not forwards from a guess.

Start from what you need to take home

Pick the number you actually want to end the year with, after tax. Not the headline day rate, the real take-home. That's the one figure that has to survive contact with reality.

Add back what the taxman takes

If you want £40,000 after tax and National Insurance take roughly 25% (a rough illustration, not your number — it depends on your actual allowances and circumstances, so check your own position with an accountant or HMRC), you don't need to charge for £40,000 of work — you need to earn about £53,000 gross, because that's what leaves £40,000 once tax is out of it. Skip this step and every rate you charge risks landing short of the number you thought you'd hit.

Add your actual business costs

Software subscriptions, insurance, equipment, an accountant, a slice of your home office — whatever you actually spend to be able to work. These come out of what clients pay you before any of it is "yours," so they belong in the target, not as an afterthought at tax time.

Divide by the days you can honestly bill, not the days in the year

This is where most guesses go wrong twice over. A year has roughly 260 working days, but you won't bill anywhere near all of them: holidays, sick days, the gaps between contracts, and the unpaid hours spent finding the next piece of work all come out first. A realistic number for most freelancers is somewhere between 150 and 200 billable days a year, not 260. Charge as if every day is billable and you've built a rate that only works in a year that doesn't exist.

The one number this produces

Target take-home, plus tax, plus costs, divided by your honest billable days — that's the day rate you actually need, not the one that merely felt right. Everything below it means working harder to end up short; everything above it is the number you can actually negotiate from.

Doing it without the arithmetic

The Day-Rate Calculator runs exactly this: your target take-home, your tax rate, your costs and your billable days in, the day, half-day and hourly rate you need out. Its Projects tab goes one step further — log what you actually quoted and what a job actually took, and see whether it really paid your floor rate or quietly didn't.

It's also included, along with every other SteadyKeel tool, in the SteadyKeel Pass — hosted online, your numbers saved to your account, always the latest version.
