Overtime Pay Value Calculator

Overtime pay looks generous on paper: typically 1.5× your normal rate (time-and-a-half) or even 2× (double time). But the actual take-home value of overtime hours is often significantly less than people expect, once taxes and other deductions are accounted for.

How Overtime Pay Works

In most countries, standard overtime rules apply to non-exempt workers:

• US (FLSA): 1.5× base rate for hours worked over 40 per week
• UK: No statutory overtime rate, but typically 1.25×–1.5× by employer policy
• EU: Varies by country, typically 1.25×–2×
• Canada: 1.5× after 8 hours/day or 44 hours/week (varies by province)

The Tax Trap, and the myth attached to it

“Overtime gets taxed more, so it’s barely worth it” is the most repeated piece of wrong advice about extra hours. Overtime is not a separate tax category. It is ordinary income, and it is taxed at your marginal rate, meaning the rate that applies to your next dollar earned.

That marginal rate is genuinely higher than the average rate you pay across your whole salary, because the earlier dollars were sheltered by the standard deduction and the lower brackets. So overtime really does keep less of each gross dollar than your salary does. But the gap is a few percentage points, not the wholesale confiscation people describe. Time-and-a-half almost always nets well above your normal after-tax rate.

True Hourly Value Formula

Net overtime rate = Base Rate × Overtime Multiplier × (1 − Marginal Tax Rate) Net normal rate = Base Rate × (1 − Effective Tax Rate)

The two rates are different on purpose. Applying one rate to both sides is the mistake that makes overtime look tax-neutral when it is not, and it is why this calculator asks for each separately. Your effective rate is your total tax divided by your total income. Your marginal rate is what the next dollar loses, and it should include federal, state, and the 7.65% FICA that comes off the top.

Where overtime actually loses its shine is further down this page: the commute you make anyway, the meal you buy because you are still at work, and the hours past 50 a week where output starts falling.

Hidden Costs of Overtime

Beyond taxes, consider additional costs:

• Commuting extra hours (if driving)
• Childcare costs for additional work hours
• Meal costs at work
• Physical and mental health, since sustained overwork reduces output and eventually costs more than it earns

Is It Worth It?

Run the numbers rather than trusting the folk wisdom. A worker on $25/hour with a 22% effective rate and a 32% marginal rate takes home $19.50 for a normal hour and $25.50 for a time-and-a-half hour. That is 131% of the normal rate, not the “barely breaks even” the myth promises.

Then subtract the real costs. If those overtime hours mean an extra $12 dinner and $5 of parking spread over four hours, the $25.50 becomes $21.25, and the premium drops from 31% to under 10%. If they mean paid childcare, it can go negative. The tax was never the problem. The overhead is.

Whether it is worth it beyond that is not a maths question. It depends on what the hours are for, and whether there is an end date.
