Day Rate Calculator
Convert between salary and contractor day rate โ or calculate the day rate you need to match your annual income as a contractor.
Convert any direction: salary to day rate, day rate to salary, or work out the day rate you must charge to hit your income target after tax.
What Is a Day Rate?
A day rate (or daily rate) is what a contractor or freelancer charges for one full day of work โ typically 8 hours. It's the standard pricing unit for contract workers, consultants, and interim professionals. Unlike an annual salary which bundles compensation with benefits, a day rate is pure gross income โ no paid holidays, no sick leave, no employer pension, no payroll tax contribution from the client. Those missing benefits are why a contractor needs to charge significantly more than a salaried equivalent to end up with the same take-home pay.
The Conversion Formulas
Gross Needed = Target Salary รท (1 โ Overhead%)
Day Rate = Gross Needed รท Billable Days (typically 220)
Day Rate โ Salary Equivalent:
Annual = Day Rate ร Billable Days
Equiv Salary โ Annual ร (1 โ Overhead%)
The overhead percentage is the key variable. It covers income tax, self-employment or contractor tax, expenses (equipment, insurance, professional memberships), the value of lost paid holidays and sick leave (typically 28โ35 days), gaps between contracts, and a profit buffer. 25โ35% is a typical buffer; risk-averse contractors or those in volatile markets run higher.
How Many Billable Days Should I Assume?
- 260 working days in a year (5 days ร 52 weeks)
- Minus public holidays: roughly 8โ12 days depending on country
- Minus time off and gaps: 10โ20 days realistic for most contractors
- 220 days is a commonly used conservative estimate; 230โ240 for busy contractors
- Overestimating billable days means you underprice โ always use a realistic, conservative figure
How to Use This Calculator
Choose your direction: Salary โ Day Rate to find the minimum you should charge to match a salaried income, or Day Rate โ Salary to see what your current rate implies about annual earnings. The salary-to-rate mode grosses up your target income by the overhead buffer and divides by billable days, showing the minimum viable day rate clearly. The rate-to-salary mode estimates the salaried equivalent so you can compare contract and permanent offers apples-to-apples.
Worked Example
A professional wants to match a $100,000 salary as a contractor, with a 30% overhead buffer. Gross needed: $100,000 รท (1 โ 0.30) = $142,857. Day rate: $142,857 รท 220 = $650/day. Conversely, a contractor charging $650/day for 220 days grosses $143,000 โ roughly equivalent to $100,000 after tax and costs. If that same contractor billed 240 days, they'd gross $156,000, leaving more after the overhead buffer. Seeing both directions makes the trade-offs between contracting and employment concrete.
Day Rate vs Hourly Rate vs Project Rate
- Day rate โ common for on-site, consultancy, and interim roles; client pays per day worked
- Hourly rate โ more granular, better for variable-length tasks; day rate รท 8
- Project rate โ fixed fee for an outcome regardless of time; best when scope is clear and you're efficient
- Day rates shift billing-hour risk to you; project rates shift scope risk to you โ choose based on how well you can estimate time

For a bottom-up rate based on your income target rather than a salary benchmark, the freelance rate calculator walks through expenses and tax more granularly.
