How the Salary to Hourly Calculator works

The formula

Step by step

1. Salary → hourly divides annual pay by (hours/week × weeks/year); the standard full-time year is 2,080 hours (40 × 52).
2. Hourly → salary multiplies the rate by weekly hours and weeks worked; overtime hours are paid at 1.5× the base rate (the FLSA floor for non-exempt work).
3. The effective hourly figure divides total annual pay by total hours (base + OT), showing how an overtime premium lifts the blended rate.
4. Identical conventions to the paycheck calculator's hourly mode, so both tools produce the same gross figures.
5. A worked example using the calculator's own defaults: $75,000 a year over 40 hours a week and 52 weeks is $36.06 an hour, $1,442.31 a week, $288.46 a day, $6,250 a month. Work 50 hours for the same salary and the rate falls to $28.85 — what the extra ten hours actually cost you.
6. Going the other way: $25 an hour, 40 hours, 52 weeks is $52,000. Add ten overtime hours a week at 1.5× and it is $71,500 — $19,500 of overtime on top of $52,000 of base — and the blended effective rate is $27.50, because the premium is spread across 50 hours rather than 40.
7. The effective hourly figure always divides total pay by total hours, base plus overtime. It is deliberately the number that falls when you work more for the same money and rises only when the extra hours are genuinely paid at a premium.

Assumptions & limitations

• Gross (pre-tax) pay only — the paycheck calculator handles taxes.
• A 5-day week for the daily figure; 1.5× overtime unless your state or contract is more generous.
• Salaried conversions divide by paid weeks — paid vacation is still paid time.
• The multiplier is applied to whatever you enter in the overtime box, with no check against the 40-hour threshold. Enter 30 base hours and 10 overtime hours and the tool returns $58,500 for a 40-hour week that would otherwise pay $52,000. Federal law only requires the premium for hours worked in EXCESS of forty in a workweek.
• Monthly and biweekly are calendar divisions — annual ÷ 12 and annual ÷ 26 — while weekly, daily and hourly are worked-time divisions using the weeks you entered. At 52 weeks these agree; at 48 weeks a $48,000 salary shows $1,000 a week but $1,846.15 biweekly, which is not two weeks' pay.
• Salary-to-hourly ignores the overtime field entirely, because a fixed salary does not grow with hours. That is correct for exempt work and wrong for a salaried non-exempt employee, who is owed overtime and should use the hourly-to-salary direction instead.
