How to read this calculator
Use total hours plus an overtime threshold when you want the calculator to split the week for you. Use split-hours mode when your payslip, rota, or payroll system already separates regular hours from overtime hours.
This is a gross-pay estimator, not a legal overtime-advisor. It does not determine exemption status, daily overtime rules, bonus-adjusted regular rate, or tax withholding.

Scenario comparison
Compare common overtime premium rates
This keeps the same hours and base rate, then compares time-and-a-quarter, time-and-a-half, double time, and your selected premium so you can see how much the premium rate changes overtime value.
An overtime calculator helps you answer more than one question at once: what your overtime rate is, how much overtime pay you earned this week, how much of that pay is the true overtime premium, and what the same schedule would mean across biweekly, monthly, and annual gross pay.
What an overtime calculator is really measuring
An overtime calculator measures the gross-pay effect of paying some hours at a premium rate instead of the base hourly wage. In the simplest model, regular hours are paid at the standard rate and overtime hours are paid at a higher rate such as 1.5x or 2x. The result is a clear split between regular pay, overtime pay, and total gross pay before tax or deductions.
That sounds basic, but the useful version of an overtime pay calculator goes further. Users usually want to know not only the overtime rate but also how much extra the premium really adds, whether the same week would materially change a biweekly or monthly paycheck, and how different premium rules compare. Those are practical decision questions, not just arithmetic questions.
This is why people search for several related terms at once: overtime calculator, overtime pay calculator, overtime rate calculator, how much overtime will I earn, and how to calculate overtime pay. The underlying intent is usually one of three things: check a paycheck estimate, compare whether extra shifts are worth it, or translate a recurring overtime pattern into a fuller earnings picture.
Competitor overtime tools often force a choice between simple weekly inputs and detailed payroll-rule workflows. This page keeps the simple workflow but removes a common friction point: if you know total hours worked and the hours before overtime starts, the calculator can derive the regular/overtime split automatically before it builds the pay table.
The most common quick-estimate workflow is total hours plus a threshold. For example, if you worked 48 total hours and overtime starts after 40, the calculator treats 40 hours as regular time and 8 hours as overtime. That mirrors the way many people think about a week before they have a payslip in front of them.
The split-hours workflow is still useful when your employer, timecard, or payroll report already separates regular hours from overtime hours. In that case, enter the split directly so the calculator does not infer anything from a threshold. Both modes feed the same gross-pay formulas, so the output remains comparable.
Threshold mode is intentionally simple. It does not apply daily overtime, seventh-day overtime, California-style double-time tiers, or weighted average regular-rate rules. If one of those rules applies, use the calculator as a transparent gross-pay planner and then reconcile the final legal calculation against official guidance or payroll policy.
Core overtime formulas and why premium-only pay matters
Most overtime calculator pages explain the overtime rate and total overtime pay, but many skip the premium-only view. That premium-only figure matters because it isolates the extra amount created by the overtime rule itself. If you worked the same overtime hours at your normal base rate, you would still have earned something for those hours. The premium-only amount shows what the overtime rule added on top.
For example, if your hourly rate is 25, overtime hours are 8, and the multiplier is 1.5, then overtime rate is 37.50 and overtime pay is 300. But only 100 of that is the overtime premium. The remaining 200 is the straight-time value of those eight hours. That distinction is helpful when you are checking a payroll estimate or asking whether a premium rate is generous enough to justify the extra time.
Regular pay = Hourly rate x Regular hours worked
This is the gross pay earned at the base rate before any overtime premium is added.
Overtime rate = Hourly rate x Overtime multiplier
A multiplier of 1.5 gives time-and-a-half and 2.0 gives double time.
Overtime pay = Overtime rate x Overtime hours worked
This is the full gross amount paid on overtime hours at the premium rate.
Overtime premium only = Hourly rate x Overtime hours worked x (Overtime multiplier - 1)
This isolates the extra pay created by the premium above straight-time pay for those same overtime hours.
Total gross pay = Regular pay + Overtime pay
The calculator combines base earnings and overtime earnings to show the full gross total for the work period.
Worked example: 25 per hour, 40 regular hours, and 8 overtime hours
Suppose your base hourly rate is 25, you worked 40 regular hours, and you added 8 overtime hours at time and a half. Regular pay is 25 x 40 = 1,000. The overtime rate is 25 x 1.5 = 37.50. Overtime pay is 37.50 x 8 = 300. Total gross pay for the week is therefore 1,300.
The overtime premium-only amount is 25 x 8 x 0.5 = 100. That means 100 of the week's pay came from the overtime premium itself, while the rest reflects either regular hours or the straight-time value of the overtime hours. If the same pattern repeated for 52 weeks, annual gross pay would be 67,600 and the premium-only portion would contribute 5,200 of that total.
That annualised view is one of the biggest practical gaps in weaker overtime calculators. A worker deciding whether recurring overtime is worth keeping does not just need a weekly number. They often need a quick estimate of biweekly gross pay, monthly pay, and annual earnings from the same pattern.
Where overtime calculator estimates go wrong
The biggest mistake is treating every overtime question as if it were only a time-and-a-half question. Some employers use double time for certain hours, holiday premiums, sector-specific rules, or union rules that sit on top of the normal overtime standard. That is why a broad overtime calculator should let you compare premium rates rather than assuming that 1.5x is always the whole story.
Another common mistake is confusing overtime pay with legal entitlement. In the United States, covered nonexempt employees generally must receive overtime pay for hours worked over 40 in a workweek under the Fair Labor Standards Act, but other jurisdictions and even some US states add different rules, such as daily overtime, different regular-rate calculations, or more protective local standards. In the UK, overtime entitlement often depends on the employment contract, though average pay still must not fall below the National Minimum Wage.
A third mistake is assuming gross overtime pay equals extra money in your pocket. Taxes, pension contributions, insurance, and other deductions can materially change take-home pay. That is why this page is intentionally framed as a gross-pay planning calculator, not a net-pay or legal-compliance engine.
Comparing time and a half, double time, and custom premiums
A strong overtime calculator should not force you to rerun the whole page just to understand how a different premium changes the result. That is why this page compares common setups using the same hours: time and a quarter, time and a half, double time, and the custom multiplier you entered.
This comparison matters because two schedules with identical hours can have meaningfully different values under different overtime rules. If your base rate is 25 and you work 8 overtime hours, moving from 1.5x to 2.0x raises the overtime rate from 37.50 to 50 and increases weekly gross pay by another 100. That kind of comparison helps when reading contracts, evaluating weekend premium offers, or checking whether a holiday shift has been paid at the promised rate.
The comparison table also makes the difference between full overtime pay and premium-only pay easier to see. Some payroll conversations use the 1.5x total overtime rate, while others focus on the extra 0.5x premium above straight time. Showing both helps prevent a common misunderstanding when people compare a calculator result with a payslip line item.
How to use overtime results for real decisions
The quickest practical use is paycheck estimation. If you already know how many regular and overtime hours were worked in a pay period, the calculator gives you a gross-pay split you can compare against a pay stub. The premium-only line is especially helpful because it shows what the overtime rule added above normal hourly pay.
If you only know total hours, use the total-hours threshold mode first. It avoids the manual step of subtracting the threshold from the total week, which is where small paycheck-estimate errors often begin.
The second use is recurring income planning. If the same overtime pattern is likely to repeat, the biweekly, monthly, and annual figures help you budget more realistically. This is useful for nurses, shift workers, warehouse employees, and hourly staff whose overtime is regular enough to affect debt planning, savings targets, or job comparisons.
The third use is schedule comparison. By keeping the same hours and changing the multiplier, you can see whether a different premium rate materially changes the value of an extra shift. That is a better decision tool than a calculator that only returns one weekly total with no context.
Use regular hours and overtime hours exactly as your pay period is already split when checking a pay estimate.
Use the annualised result only when the same weekly pattern is realistic enough to repeat.
Treat the premium-only amount as the extra value created by the overtime rule itself.
Keep taxes, unpaid breaks, bonuses, commissions, and shift differentials separate unless your payroll rule clearly rolls them into the regular rate.
This calculator does not determine whether a worker is exempt or nonexempt, whether daily overtime rules apply, how bonuses should change the regular rate, or how a specific employer handles holiday or weekend premiums. It also does not calculate take-home pay after deductions.
Those limits are deliberate. A broad overtime calculator is strongest when it stays transparent about what it does well: base pay plus premium pay on the hours you enter, with repeat-pattern projections across common pay periods. For legal interpretation or exact payroll reconciliation, you still need the relevant official wage guidance, contract terms, and payroll policy.

Frequently asked questions
How is overtime pay calculated?
Overtime pay multiplies your regular hourly rate by an overtime multiplier, most commonly 1.5x for time and a half or 2x for double time. Total gross pay is then regular hours at base rate plus overtime hours at the higher rate. A fuller overtime calculator can also separate the premium-only amount so you can see what the overtime rule added above straight-time pay.
How do you calculate overtime rate from hourly pay?
Multiply the hourly pay by the overtime multiplier. For example, 20 per hour at time and a half gives an overtime rate of 30 per hour, while double time gives 40 per hour. The overtime rate calculator part of the page shows that premium rate immediately.
What is the difference between overtime pay and overtime premium?
Overtime pay is the full amount paid on overtime hours at the premium rate. Overtime premium is only the extra amount created by the multiplier above straight-time pay. If your hourly rate is 25 and you work 8 overtime hours at 1.5x, overtime pay is 300 but the premium-only amount is 100.
Can I use this as a time and a half calculator?
Yes. Enter 1.5 as the overtime multiplier and the calculator works as a time and a half calculator. The dedicated time-and-a-half page is narrower, while this broader overtime calculator also helps compare 1.25x, 1.5x, 2.0x, and custom premiums.
Can I use a different overtime multiplier?
Yes. Many workers use 1.5x, but some contracts or holiday rules use double time or another premium. Enter the multiplier that matches the scenario you want to estimate and use the comparison table to see how the premium changes overtime value.
Can I enter total hours instead of pre-calculating overtime hours?
Yes. Use the total hours plus threshold mode when you know the full hours worked and the point where overtime starts. For example, 48 total hours with overtime after 40 becomes 40 regular hours and 8 overtime hours. Use split-hours mode instead when a payslip or rota already gives you regular and overtime hours separately.
Does this calculator include payroll taxes or take-home pay?
No. The result is gross pay before income tax, national insurance, social security, pension, or other deductions. Overtime can affect withholding, but the actual take-home result depends on your payroll setup and tax rules.
Is overtime always paid after 40 hours?
Not always. The 40-hour workweek is a common US rule for covered nonexempt employees, but some states, sectors, contracts, or countries use different thresholds or additional daily rules. This page estimates gross overtime from the hours and multiplier you enter, not the legal rule you should be using.
Why does the calculator show biweekly, monthly, and annual pay too?
Many people do not just want a one-week overtime answer. They want to know what recurring overtime means for a biweekly paycheck, monthly budget, or annual gross earnings. Those projections are useful when the same overtime pattern is regular enough to repeat.
Can overtime results differ from my actual payslip?
Yes. Real payroll can change the answer if your employer uses daily overtime, bonus-adjusted regular-rate rules, holiday premiums, unpaid breaks, shift differentials, union terms, or deductions. This calculator is strongest as a transparent gross-pay planning tool rather than a full payroll simulation.
