How the Freelancer Rate Calculator Works
The Core Formula
Your minimum rate is the hourly amount you must charge to cover every cost and take home your income goal — with zero profit cushion. Your recommended rate adds a profit margin on top of that.
Self-Employment Tax (15.3%)
Unlike employees who split FICA taxes with their employer, freelancers pay both sides: 12.4% Social Security + 2.9% Medicare = 15.3% total. This applies to 92.35% of net self-employment income (after the half-SE-tax deduction). We calculate this automatically based on your income goal and add it to your total cost basis.
Billable Hours Calculation
We calculate effective billable hours as your stated annual billable hours minus your PTO days (converted to hours at 8 hrs/day). For example, if you enter 1,200 billable hours and 15 PTO days, your effective billable hours are 1,080. This is the denominator in your rate calculation.
Be realistic: if you work 40 hrs/week but only 60% are genuinely billable, your starting number should be 1,248, not 2,080.
Retirement Contribution
We calculate your annual retirement contribution as a percentage of your target income. A 10% contribution on a $100,000 income goal = $10,000/year that must be covered by your rate before you see the money. Solo 401(k) and SEP-IRA contributions are both pre-tax, reducing your overall tax burden.
Profit Margin
Your recommended rate multiplies your minimum rate by (1 + profit margin %). A 20% margin on a $75/hr minimum gives a $90/hr recommended rate. This cushion covers slow months, unexpected expenses, scope creep, and reinvestment in your business.
