Overtime Calculator

Estimate gross overtime pay from an hourly rate, regular hours, and overtime hours — or total hours with a weekly OT threshold. Default multiplier is 1.5 (time and a half). Everything runs in the browser.

Stays on your device

An overtime calculator answers a simple payroll question: if you work past a regular-hour threshold, what is that week worth before taxes? Enter your hourly rate, choose Total hours (with a threshold, often 40) or Regular + OT hours, and set the multiplier (1.5 is the usual default).

Regular pay = hourly rate × regular hours. Overtime pay = hourly rate × multiplier × OT hours. Example: $20/hr, 40 regular hours, and 5 OT hours at 1.5× is $800 + $150 = $950. The same 45 hours in Total hours mode with a 40-hour threshold produces the same split.

Results are educational gross estimates, not legal or tax advice. Eligibility, daily overtime, and premiums can differ. Totals never leave the device, and there is no account.

Frequently asked questions

How does an overtime calculator work?

An overtime calculator multiplies regular hours by your hourly rate, then multiplies overtime hours by the same rate times an overtime multiplier (often 1.5). Regular pay + overtime pay equals total gross pay for the period. You can enter regular and OT hours separately, or enter total hours and a weekly threshold (commonly 40) so the page splits them for you.

What is time and a half overtime?

Time and a half means overtime hours are paid at 1.5 times the regular hourly rate. Example: $20/hr with 40 regular hours and 5 OT hours is $800 regular + $150 OT = $950. Change the multiplier to 2 for double time when that applies to your situation.

How do you calculate overtime after 40 hours a week?

Under a common weekly model, hours at or under the threshold (often 40) are paid at the regular rate, and hours above the threshold are paid at the overtime rate. In Total hours mode, enter 45 hours with a 40-hour threshold: 40 regular + 5 OT. Your employer or local rules may use a different threshold or daily overtime — adjust the inputs to match.

What is the difference between regular rate and overtime rate?

The regular (straight-time) rate is your base hourly pay. The overtime rate is that base times the overtime multiplier. At 1.5×, a $22 hourly rate becomes a $33 OT rate. This page shows both so you can check the math before payday.

How do weekly and biweekly overtime estimates differ?

This calculator estimates one week (or one entered period) of gross pay. The biweekly figure simply doubles that total, which is useful if two identical weeks make up a biweekly paycheck. Real biweekly totals can differ if hours change week to week, or if your plan uses a different overtime workweek.

Does this overtime calculator include taxes?

No. Every total is gross pay before federal, state, FICA, retirement, or other deductions. Pair it with a paycheck tool if you need a broader gross-pay picture — still not a tax engine.

Does this overtime calculator upload my pay data?

No. Hourly rate, hours, threshold, and multiplier are calculated in your browser. Nothing is sent to a server or stored on our side.

Is this overtime calculator legal advice?

No. Results are an educational gross-pay estimate from the numbers you enter. Overtime eligibility, daily vs weekly OT, exemptions, and premiums vary by employer and jurisdiction. Check your handbook, payroll, or a qualified advisor for your situation.
