How to Calculate Your Freelance Day Rate
The day rate question comes up on every new client call. Quote too low and you leave money on the table. Quote too high without justification and you lose the deal. The answer comes from working backwards from your income target — not from guessing what sounds reasonable.
The formula
Your day rate starts with three numbers: your income target, your tax burden, and the number of days you can actually bill.
Most freelancers have 220–240 billable days per year. That's 52 weeks × 5 days = 260, minus roughly 20 vacation days, 10 sick/admin days, and 10–15 days for proposals and unbillable client work.
A worked example
Say you want to net $80,000 after tax. In the US, self-employment taxes and federal/state income tax might run 33–38% of gross income. At 35%, you need to earn approximately $123,000 gross to take home $80,000.
Add overhead: laptop depreciation, software subscriptions, co-working space, accounting — roughly $5,000–$8,000 per year.
Total gross needed: ~$131,000.
Divide by 230 billable days: ~$570/day.
Round up to a clean number: $600/day. That's your baseline.
What to factor in
- Taxes: Set aside 25–40% depending on your country. Your day rate must cover your entire tax liability — not just income tax, but self-employment or national insurance contributions too.
- Unpaid time: Client calls, proposals, invoicing, and admin don't get billed but they cost you hours. Budget 15–20% of your working hours for non-billable work.
- Vacation and sick days: 20 vacation + 10 sick = 30 days. Subtract from 260 working days → 230 billable days available.
- Utilisation rate: Most freelancers aren't fully booked all year. A 75–80% utilisation rate is realistic, especially in the first year. 230 × 0.75 = ~173 truly billable days. Dividing your gross target by 173 gives a more conservative but sustainable rate.
Day rate vs. hourly rate
For engagements lasting a week or longer, day rates are simpler:
- No debates about partial hours
- Clients know the exact daily cost upfront
- Easier to track: you work the day, you bill the day
For shorter or variable work — a few hours per task, irregular schedules — hourly billing is cleaner and gives clients more flexibility. You can always offer both and let the client choose.

What is a good day rate for a freelance developer?
In 2026, mid-level freelance developers typically charge $400–$800 per day in the US and UK. Senior or specialist developers (DevOps, ML, security) charge $700–$1,500+ per day. Your location, niche, and client type all affect the market rate.
How do I convert my day rate to an hourly rate?
Divide by 8. A $600/day rate equals $75/hour. Use the Hourly Rate Calculator on time2bill to derive this automatically from any fixed price or billing period.
Should I charge the same rate for all clients?
Not necessarily. You can charge more for enterprise clients (larger budget, higher value), for urgent work, or for work outside your core specialty. A tiered pricing approach is common among experienced freelancers.
What if a client wants a monthly rate?
Multiply your day rate by 20, the standard working days per month. $600/day × 20 = $12,000/month. Use the Monthly Adjuster on time2bill to handle months where days are added or missed.
