Hourly to Salary Calculator: Annual, Monthly & Weekly Pay

How an hourly rate becomes a salary

On the defaults — $25.00 an hour, 40 hours a week, 52 weeks a year, no overtime — the annual salary is $52,000.00, the monthly pay is $4,333.33, the weekly pay is $1,000.00, the biweekly pay is $2,000.00, the daily pay is $200.00, and the effective hourly rate is $25.00. The whole calculation is three moves: multiply the rate by the hours in the year, divide the salary by the weeks for the pay periods, and add overtime at time-and-a-half on the extra hours.

Five things about the model are worth stating plainly. First, the hours in a year are 40 × 52 = 2,080. Second, the annual salary is $25.00 × 2,080 = $52,000.00. Third, the monthly pay is $52,000.00 ÷ 12 = $4,333.33, the weekly pay is $52,000.00 ÷ 52 = $1,000.00, the biweekly pay is 2 × $1,000.00 = $2,000.00, and the daily pay is $1,000.00 ÷ 5 = $200.00 (a five-day week). Fourth, overtime hours are EXTRA hours beyond the base week, paid at 1.5 × the hourly rate — at the defaults there are none, so the overtime pay is $0.00 and the effective hourly rate stays $25.00. And fifth, this is GROSS pay before tax, withholding, and deductions — take-home pay is lower; it assumes the same hours every week and no unpaid time off beyond the weeks you enter; daily pay assumes a five-day week; all listed in Accuracy & limitations.

The worked example, line by line

Setup: $25.00 an hour, 40 hours a week, 52 weeks a year, 0 overtime hours.

Line 1 — the hours in the year. The hours in the year are 40 × 52 = 2,080.

Line 2 — multiply the rate by the hours. The annual salary is $25.00 × 2,080 = $52,000.00.

Line 3 — divide the salary by the periods. The monthly pay is $52,000.00 ÷ 12 = $4,333.33, the weekly pay is $52,000.00 ÷ 52 = $1,000.00, the biweekly pay is 2 × $1,000.00 = $2,000.00, and the daily pay is $1,000.00 ÷ 5 = $200.00.

Line 4 — overtime and the effective rate. With 0 overtime hours the overtime pay is $0.00 and the effective hourly rate is $52,000.00 ÷ (40 × 52) = $25.00 — the same as the base rate, because no overtime lifts it.

• The worker on 5 overtime hours a week: they learn the overtime adds $9,750.00 and the annual pay is $61,750.00 — and they check the 9.23 h/wk reverse to see the overtime for a $70,000.00 salary.
• The worker taking 4 weeks off: they learn 48 weeks a year is $48,000.00 — and they check the 50.00 wk reverse to see the weeks for a $50,000.00 salary.
• The worker offered $15.00 an hour: they learn the salary is $31,200.00 a year — and they check the $48.08 reverse to see the rate for a $100,000.00 salary.

Accuracy & limitations

The math is first-principles: the annual salary is the hourly rate times hours per week times weeks per year, overtime is 1.5 times the hourly rate on extra hours beyond the base week, and each figure is rounded to cents half-up. What the model cannot do is tell you what YOU take home: this is GROSS pay — it does NOT model tax, withholding, or deductions; it does NOT model benefits, bonuses, or commission; it does NOT model hours that change week to week; it assumes the same hours every week and no unpaid time off beyond the weeks you enter; and daily pay assumes a five-day week. Use it to compare offers and check your rate — then check your pay stub for what actually lands.
