Overtime calculator guide
Overtime pay is your ordinary hourly rate scaled up by a multiplier for hours worked beyond the normal schedule. This calculator multiplies the hourly rate by the number of overtime hours and by the multiplier, then shows the resulting overtime rate per hour and the base rate for comparison. It is meant for checking a payslip line, estimating what a run of late shifts will add to a pay period, or deciding whether an extra shift at a given premium is worth taking. The multiplier is your choice because the rules differ: 1.5 is common for weekly hours above 40 in the United States under the Fair Labor Standards Act, while other countries, collective agreements, and individual contracts use 1.25, 1.5, 2.0, or a flat allowance, and some salaried roles receive no overtime premium at all. The result is gross pay before income tax, social security contributions, pension deductions, and any regular pay for the same period, which is not included here.
Overtime rate ($/hour) = hourly rate ($/hour) × multiplier. Overtime pay ($) = hourly rate × overtime hours × multiplier.
Worked example with the default inputs: a base rate of $25 per hour, 8 overtime hours, and a multiplier of 1.5. Overtime rate = $25 × 1.5 = $37.50 per hour. Overtime pay = $25 × 8 × 1.5 = $300.00. The calculator shows $300.00 as the estimated overtime pay, with the $37.50 overtime rate and the $25.00 base rate underneath. If those 8 hours were paid at double time instead, the multiplier would be 2.0 and the pay $25 × 8 × 2 = $400.00.
The hourly rate is currency per hour and the result is in the same currency; there is no currency conversion. Overtime hours can be fractional, so 7 hours 30 minutes is 7.5. The multiplier is a plain factor: enter 1.5 for time-and-a-half or 2 for double time, not 50 or 150. If your contract pays a fixed per-hour premium instead of a multiplier, add it to the base rate and use a multiplier of 1.
Treat this as a gross planning figure. Deductions, tax codes, benefit contributions, overtime rules, and local employment law all change what actually reaches your account, and they vary by jurisdiction and employer. Check the number against your payslip or contract before relying on it for a budget or a negotiation. On this page the figure rests entirely on hourly rate, overtime hours and overtime multiplier, so start there if the overtime calculator returns something you did not expect.
Good to know: the result covers only the overtime hours. Add regular pay for the standard hours separately if you want a period total. In jurisdictions where the overtime rate is based on a regular rate that includes shift differentials or non-discretionary bonuses, entering the bare hourly wage understates the premium. Hours above a daily threshold and hours above a weekly threshold can be counted differently, so do not double-count the same hours under both rules.
Use the result as a gross planning estimate. Confirm payroll, overtime, tax, benefits, and employment-rule assumptions with your employer or the relevant authority.
How it works
Estimate overtime pay from a base rate and extra hours. This tool explains the calculation so you can adjust the assumptions to match your situation.
Worked example
With Hourly rate = 25 $/hour · Overtime hours = 8 hours · Overtime multiplier = 1.5 × → $300.00 (estimated overtime pay). Change an input above and this example updates with your numbers.
Common questions
Multiply your hourly rate by the overtime multiplier to get the overtime rate, then multiply by the overtime hours. At $25 an hour with time-and-a-half, the overtime rate is $37.50 and 8 hours of overtime pay $300 before tax.
Time and a half means a multiplier of 1.5, so $25 × 1.5 = $37.50 per overtime hour. Eight such hours are worth $300, and a full 40-hour week at that rate would be $1,500, all before deductions.
It depends on the law and your contract. In the United States the federal minimum is 1.5 times the regular rate for hours over 40 in a week. Some countries and agreements pay 1.25 for the first hours and 1.5 or 2.0 for later ones, or 2.0 on public holidays. Enter the multiplier that applies to you.
No. The result is gross overtime pay. Income tax, social contributions, and pension deductions will reduce it, and because overtime lifts the period total it may be taxed at a higher marginal rate than usual, though the underlying rate is not changed by working extra hours.
Sometimes. Many salaried roles are exempt from overtime rules, but eligibility depends on duties and salary thresholds set by national or state law. If you are eligible, convert your salary to an hourly rate first with the salary-to-hourly calculator and use that as the base rate here.
