How to Calculate Your Freelance Day Rate

Start from the income you want, not the market

Most freelancers set their first day rate by looking at what others charge or by dividing their old salary by 260 working days. Both shortcuts ignore the costs that employment used to hide. A sustainable day rate is built from the bottom up: decide what you need to take home, work out everything that has to be paid before that money reaches you, then spread the total across the days clients will actually pay for.

The result is a floor, not a ceiling. You can and often should charge more, but you should know the number below which every project quietly loses you money.

Step 1: Gross up your take-home income for tax

If you want to keep 75,000 a year after tax and your effective tax rate is 25%, you need to earn 75,000 ÷ (1 − 0.25) = 100,000 before tax. Use your effective rate — total tax paid divided by total income — rather than your highest bracket. Include self-employment, social security or national insurance contributions, because as a freelancer you usually pay both the employee and employer share.

Step 2: Add business expenses

List everything the business pays for in a year: laptop and equipment replacement, software subscriptions, accounting fees, professional insurance, co-working space, phone and internet, training, conference tickets and marketing. Expenses are usually deductible, so they are added after the tax gross-up. With 6,000 of expenses, the example becomes 106,000.

Step 3: Add a profit buffer

A business that only covers its costs has no room for a late-paying client, a slow quarter or a pension contribution. A buffer of 10–20% is common. Applying 10% to 106,000 gives a revenue target of 116,600.

Step 4: Work out your real billable days

This is where most rate calculations go wrong. Start with the days you work each week, multiply by the weeks you will actually work (52 minus holidays, sick days and gaps between contracts), then multiply by your utilization — the share of working time you can bill to clients.

Working five days a week for 46 weeks at 70% utilization gives 5 × 46 × 0.70 = 161 billable days, far fewer than the 260 working days of a full-time salaried year.

Step 5: Divide

Revenue target ÷ billable days = minimum day rate. In the example, 116,600 ÷ 161 ≈ 724 per day. If a billable day is eight hours, that is about 90.50 per hour; for a 7.5-hour day it is about 96.50. The same person might have earned around 385 a day as an employee on the same take-home pay — which is why freelance day rates often look high from the outside.

This number is your floor: the lowest day rate that still pays your salary, taxes, costs and profit. Never quote below it, and use it to set the cheapest option in a project proposal rather than as the price for every job.

Sanity-check against the market

Once you have your floor, compare it with rates for your skill and region. If the market pays more, charge the market rate and enjoy the margin. If the market pays less, the gap tells you something useful: reduce expenses, raise utilization, specialize into a better-paid niche, or reconsider the income target. Recalculate whenever your costs, tax situation or workload changes, and at least once a year.
