One regular hour at your base rate set against your overtime hours at the premium rate, then the tax at your marginal rate and what you keep. Overtime is taxed as ordinary income — the same rate schedule as the rest of your pay — so the only difference in the rate column is the overtime multiplier, not the tax.

$375 gross, $292.50 net, at an overtime rate of $37.50
A $25 hourly rate at time-and-a-half is $37.50 an hour. Ten hours is $375 gross, and at a 22% marginal rate the tax is $82.50, leaving $292.50 — about $29.25 an hour after tax.
That after-tax hourly figure is the one to compare against. The decision is not whether $375 is worth having; it is whether $29.25 an hour is worth ten hours of your time, given what else those hours could be. Stated that way, the multiplier matters far less than people assume: time-and-a-half on a 22% rate nets barely more per hour than the gross regular rate.
It does not push your regular pay into a higher bracket
Overtime is ordinary income and sits on top of regular earnings, so it is taxed at whatever band that additional income falls into. The persistent belief that overtime is "taxed more" comes from two places: the marginal rate is genuinely higher than the effective rate people are used to, and payroll withholding on a large pay period can over-withhold temporarily.
Neither means overtime is penalised. The extra income is taxed at your marginal rate exactly as any other extra income would be, and if withholding overshot, the difference returns at filing. Declining overtime to avoid a higher bracket always leaves you with less money, never more.
Benefit tapers and allowance withdrawals, not tax bands
There are real cases where extra income is worth much less than the marginal rate suggests, and they are not tax bands. Income-tested benefits that taper, childcare support that cuts off at a threshold, and allowances that withdraw as income rises can all produce effective marginal rates far above any published band.
Someone near such a threshold should compute the combined effect before taking regular overtime, because the answer is occasionally that additional hours are worth close to nothing. Use the marginal rate field here to enter the true combined rate rather than the income tax band, and the net figure becomes meaningful.
Social contributions, and everything the multiplier depends on
Only income tax is applied. Payroll or social contributions apply to overtime as to any other pay and will reduce the net further, typically by several more points unless an annual ceiling has already been reached.
The multiplier itself is a legal and contractual question that varies widely: time-and-a-half above a weekly threshold in some jurisdictions, double time for certain days or hours in others, and no premium at all for salaried exempt roles. Enter the multiplier your own arrangement actually provides rather than assuming 1.5.
