Tax estimate

This estimates paycheck withholding, not your final tax bill.

Use this extra shift calculator to estimate how much a pickup shift may actually add to your paycheck after overtime, shift differentials, weekend pay, and estimated taxes. It is designed for nurses and hourly healthcare workers who want a quick take-home estimate before saying yes to extra work.

How it works

Start with your rate, regular hours, and the extra work you are considering. The calculator estimates the added gross pay, estimated taxes, and the paycheck difference.

Use advanced options for overtime threshold, differentials, deductions, and pay frequency when you want the estimate to look more like your real paycheck.

Good to know

  • Hours above your overtime threshold are paid at 1.5 times your base hourly rate.
  • Differentials are added per hour and are not multiplied by overtime in this estimate.
  • ZIP estimates are rough and may not match your actual paycheck withholding.

This calculator is an estimate only. It is not tax, legal, payroll, or financial advice. Your actual paycheck can vary based on your employer, benefits, withholding, state taxes, city or local taxes, and payroll rules.

FAQ

Does this include overtime?

Yes. Hours above the overtime threshold are paid at 1.5 times your base hourly rate.

Are differentials multiplied by overtime?

No. This estimate adds differentials per hour and does not multiply them by overtime.

What does the ZIP estimate include?

It estimates federal income tax, payroll tax, and state income tax from your ZIP code. It may not include city, county, or employer-specific withholding rules.

Do pretax deductions reduce the extra shift amount?

Pretax deductions are used to estimate your regular paycheck. The extra shift estimate applies tax directly to the added gross pay.

Will this match my paycheck exactly?

Probably not exactly. Payroll systems can include state rules, benefit changes, bonuses, garnishments, and other details.
