Your day rate is not your salary divided by 220
The mistake almost every new freelancer makes is dividing the salary they want by the days they will work. A $100,000 take-home target divided by 220 billable days is $454.55 a day — and it is wrong, because it forgets two things: the overhead of running the business, and the tax. The day rate has to cover the take-home target PLUS overhead, grossed up for tax. The formula is: annual gross needed = take-home × (1 + overhead) / (1 − tax). On the defaults — $100,000 take-home, 15% overhead, 25% tax — that is $100,000 × 1.15 / 0.75 = $153,333.33 a year gross. The day rate is the gross divided by the billable days: $153,333.33 / 220 = $696.97 a day. The hourly rate is the day rate divided by the hours in a day: $696.97 / 8 = $87.12 an hour. The weekly rate is the day rate times five: $696.97 × 5 = $3,484.85. The monthly gross is the annual gross divided by 12: $153,333.33 / 12 = $12,777.78. The gross-up roughly doubles the naive answer: $454.55 a day leaves you short by more than half, because every dollar you keep has to survive both the overhead and the tax first.

At the defaults — target income $100,000, 220 billable days, overhead 15%, tax buffer 25%, 8 hours a day — the annual gross needed is $153,333.33, the day rate is $696.97, the hourly rate is $87.12, the weekly rate is $3,484.85, and the monthly gross is $12,777.78. Check the identities: gross = income × (1 + overhead) / (1 − tax); day = gross / days; hourly = day / hours; weekly = day × 5; monthly = gross / 12. Monthly figures are rounded to the cent, so monthly × 12 can differ from the annual gross by a few cents; totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum.
The worked example, line by line
Setup: target income $100,000, 220 billable days, overhead 15%, tax buffer 25%, 8 hours a day.
Line 1 — the annual gross needed. $100,000 × (1 + 0.15) / (1 − 0.25) = $100,000 × 1.15 / 0.75 = $153,333.33.
Line 2 — the day rate. $153,333.33 / 220 = $696.97.
Line 3 — the hourly rate. $696.97 / 8 = $87.12.
Line 4 — the weekly rate. $696.97 × 5 = $3,484.85.
Line 5 — the monthly gross. $153,333.33 / 12 = $12,777.78.
Line 6 — the naive answer, for comparison. $100,000 / 220 = $454.55 — the rate that forgets overhead and tax, and leaves you $242.42 a day short.
Reverse: the day rate for an $80,000 take-home target is $557.58 (exact 557.5758); at $557.58 the take-home is $80,000.61 ($0.61 over), at $557.57 it is $79,999.17 ($0.83 under) — $557.58 is the nearest. The billable days for a $120,000 take-home target at $800/day are 230 (exact); at 230 days the take-home is $120,000.00 exactly, at 229 days it is $119,478.26. The overhead for a $650/day rate is 7.25% (exact); at 7.25% the day rate is $650.00 exactly. The tax buffer for a $750/day rate is 30.30% (exact 30.3030%); at 30.30% the day rate is $749.97 ($0.03 under $750). At $900/day, 200 billable days, 20% overhead and 30% tax, the take-home is $105,000.00 on a gross of $180,000.00.
Every branch, checked
Target income $75,000: gross $115,000.00, day $522.73, hourly $65.34. A lower target drops the rate by almost $175 a day.
Target income $150,000: gross $230,000.00, day $1,045.45, hourly $130.68. Six figures of take-home needs a four-figure day rate.
180 billable days: gross $153,333.33, day $851.85, hourly $106.48. Fewer billable days means each one has to earn more — the gross does not change, only the rate.
250 billable days: gross $153,333.33, day $613.33, hourly $76.67. More billable days spread the same gross thinner.
Overhead 0%: gross $133,333.33, day $606.06, hourly $75.76. Even with no overhead at all, the rate is still $606.06 — a $600/day rate cannot fund a $100k take-home at 220 days and 25% tax.
Overhead 30%: gross $173,333.33, day $787.88, hourly $98.48. Heavy overhead adds almost $91 a day to the rate.
Tax buffer 20%: gross $143,750.00, day $653.41, hourly $81.68. A lower tax buffer is the cheapest way to lower the rate — if your real tax rate is 20%, charge for 20%, not 25%.
Tax buffer 30%: gross $164,285.71, day $746.75, hourly $93.34. Five points of tax adds almost $50 a day.
6 hours a day: day $696.97, hourly $116.16. The day rate does not change — only the hourly rate does, because the same day is split into fewer hours.
10 hours a day: day $696.97, hourly $69.70. Longer days make the hourly rate look cheaper, but the day rate is what the client pays.
Reverse — the other way round: the day rate for an $80,000 take-home target is $557.58 (exact 557.5758); the billable days for a $120,000 target at $800/day are 230 (exact); the overhead for a $650/day rate is 7.25% (exact); the tax buffer for a $750/day rate is 30.30% (exact 30.3030%); at $900/day, 200 days, 20% overhead and 30% tax, the take-home is $105,000.00.
What the defaults assume
The model assumes the overhead and the tax are percentages of the gross-up as stated: gross = income × (1 + overhead) / (1 − tax), and it assumes every billable day earns the same day rate, the overhead is a fixed percentage, and the tax buffer is a flat rate. It assumes 220 billable days a year — about 260 weekdays minus holidays, sick days, and unpaid admin — and 8 billable hours a day. It leaves out the unpaid time you spend finding clients, the gaps between contracts, retirement contributions, and health insurance beyond what sits in the overhead. With a target income of $0, everything is $0.00. With overhead of 100%, the day rate is $1,212.12 (gross $266,666.67, hourly $151.52). With a tax buffer of 0%, the day rate is $522.73 (gross $115,000.00, hourly $65.34). With 365 billable days, the day rate is $420.09 (hourly $52.51) — but nobody bills 365 days a year. With 0 billable days the calculator shows an error, not $0, because a day rate needs a day to divide by. Rounding convention: totals are computed from unrounded values, so rounded parts may differ by a cent from their rounded sum; the reverses are nearest-value solutions, and the exact unrounded figures (557.5758, 230, 7.25%, 30.3030%) are stated wherever the rounded figures appear.

Who uses this
- The freelancer quoting their first client: they learn a $100,000 take-home target means a $696.97 day rate, not $454.55 — so they know to quote $697 a day, and they check the $80,000 reverse ($557.58) before offering a discount.
- The contractor comparing a day rate with a salary: they learn the day rate of $696.97 is $87.12 an hour and $153,333.33 a year gross — so they know the contract has to beat the salary by the overhead and the tax, and they check the 180-day branch ($851.85) before assuming every weekday is billable.
- The consultant whose overhead just jumped: they learn 30% overhead pushes the day rate to $787.88 from $696.97 — so they know the new software and insurance cost $91 a day, and they check the 0% overhead branch ($606.06) before deciding what the business really costs to run.
- The freelancer offered $650 a day: they learn $650 a day funds a $100k take-home only if overhead is 7.25% — so they know the offer works only with lean overhead, and they check the $750 reverse (30.30% tax) before accepting a rate that leaves the tax short.
Accuracy & limitations
The math is exact for the numbers you enter: annual gross = income × (1 + overhead) / (1 − tax); day rate = gross / billable days; hourly rate = day rate / hours per day; weekly = day rate × 5; monthly = gross / 12. What the model cannot do is know your real tax rate: check it, because the tax buffer is a flat percentage and real tax is progressive — and check the overhead, because the business costs are the part most freelancers underestimate. It assumes every billable day earns the same day rate, the overhead is a fixed percentage of the take-home, and the tax buffer is a flat rate. It leaves out the unpaid time spent finding clients, the gaps between contracts, retirement contributions, and health insurance beyond what sits in the overhead. It is a rate calculator, not tax advice: for what lands in your bank account, see the take-home pay calculator; for what your hour is worth, see the freelance hourly rate calculator.

Method: annual gross needed = take-home income × (1 + overhead) / (1 − tax buffer); day rate = annual gross / billable days; hourly rate = day rate / hours per day; weekly rate = day rate × 5; monthly gross = annual gross / 12. The day rate must cover the take-home target PLUS overhead, grossed up for tax — a $100,000 take-home target is NOT $100,000 / 220 = $454.55 a day. Defaults: target income $100,000, billable days 220, overhead 15%, tax buffer 25%, hours per day 8 → annual gross $153,333.33, day rate $696.97, hourly rate $87.12, weekly rate $3,484.85, monthly gross $12,777.78.
