Overtime Calculator

Overtime estimate formula

For each separate week, this calculator uses regular pay = hourly base rate × regular hours and overtime pay = displayed overtime rate × overtime hours entered by you. The displayed overtime rate is the hourly base rate multiplied by your chosen multiplier and rounded half up to cents before the hours multiplication. Regular pay plus overtime pay gives that week's gross estimate.

At $20 per hour, 40 regular hours, 5 overtime hours, and 1.50×, the receipt shows $800 regular pay, a $30 overtime rate, $150 overtime pay, and $950 gross. Changing the same current calculation to 35 regular hours and 0 overtime hours produces $700 + $0 = $700; the old overtime subtotal is retired from the result, copy receipt, and CSV.

Two workweeks stay separate

The Department of Labor's general principles describe a workweek as a fixed, recurring 168-hour period and say each workweek stands alone under the FLSA; averaging hours over two or more workweeks is generally not permitted. That is why Week 1 and Week 2 have separate inputs and receipts here.

For example, Week 1 at $20 / 40 regular / 5 overtime / 1.50× is $950. Week 2 at $20 / 35 regular / 0 overtime / 1.50× is $700. The combined display is a simple sum: $1,500 regular + $150 overtime = $1,650 gross. It does not reinterpret the two weeks as one 80-hour period.

Why a pay stub can differ

This four-field model uses the hourly base rate you supply. The legal regular rate may include bonuses, commissions, lodging, or other remuneration, while some payments can be excluded. Coverage, exemptions, hours worked, special federal rules, collective bargaining terms, and more-protective state laws also require facts this page does not collect. Employer time and payroll rounding can use a different convention.

The Department of Labor's own Advisor calls its output a sample and warns that actual overtime pay may differ. Use that official Advisor, an applicable state labor agency, your complete pay records, or a qualified professional when you need an eligibility or legal-pay determination.

Overtime and the 2026 federal deduction

This calculator does not estimate withholding or the separate qualified-overtime deduction. IRS FS-2026-13 says the deduction is limited to qualifying compensation and taxpayers, and does not make overtime compensation excluded from gross income or generally exempt from income-tax withholding, Social Security, or federal unemployment taxes.

Private, browser-only calculation

Calculation and receipt creation happen on your device, and pay values are not sent to ToolNeko or analytics. Copy receipt writes the current receipt to your system clipboard; Download CSV saves a file through your browser. Your rates, hours, multiplier, totals, and exported rows are not placed in the URL, site storage, cookies, requests, analytics, or error reports. Once this page's static assets have loaded, new one- and two-week inputs continue to work offline.
