Direct answer
Calculate straight-time earnings for each rate, find the regular-rate method payroll uses, then apply the overtime premium to the overtime hours.
Some payroll systems use a weighted average for mixed-rate overtime; others use a policy-specific method. The straight-time total should be visible either way.
Use this when you are estimating overtime when the same week includes two different hourly rates. The strongest answer comes from the actual pay stub, timesheet, offer letter, payroll setting, benefits election, deduction notice, or bank deposit record, not from a remembered schedule or rough paycheck amount.
Open Overtime Pay CalculatorFormula and realistic example
Formula: Weighted regular rate = total straight-time earnings / total hours; overtime premium = overtime hours x weighted regular rate x 0.5 when straight time is already included.
Example: If 30 hours are paid at $18 and 15 hours at $24, straight-time earnings are $900. The weighted rate is $20.00. Five overtime hours add a $50 half-time premium when straight time is already paid.
Keep the example visible while replacing the numbers. That catches the mistakes people usually miss: the wrong start date, a duplicate lunch deduction, the wrong rate, or a skipped holiday.

Copy-ready result
Two-rate week: 30 x $18 + 15 x $24 = $900 straight time. Weighted rate: $20. Overtime premium for 5 hours at half-time: $50. Estimated gross: $950 before deductions.
If you paste this into a payroll note, PTO request, invoice follow-up, or manager message, keep the assumption sentence with it. A number without the rule behind it is hard to check later.

Open Overtime Pay CalculatorReal situations this covers
These are the kinds of everyday cases where a quick calculator answer is useful, but the notes still matter.
Key checks
- Employee works a lower-rate role early in the week and a higher-rate role on Saturday.
- Warehouse worker receives different rates for two departments.
- Training hours and production hours have different base rates.
Step-by-step method
Key checks
- Write down the hours, rate, pay frequency, overtime rule, shift premium, tips, deductions, retirement percentage, benefits, and tax estimate.
- Check the source record: pay stub, timesheet, offer letter, payroll setting, benefits election, deduction notice, or bank deposit record.
- Apply this rule: Weighted regular rate = total straight-time earnings / total hours; overtime premium = overtime hours x weighted regular rate x 0.5 when straight time is already included.
- Run one clean scenario first, then add special cases only when they actually apply.
- Save the final number with the assumption note before using it for a paycheck estimate, budget check, payroll question, raise comparison, or offer review.
What can change the answer
The answer can change when gross versus net pay, weekly overtime, pre-tax deductions, after-tax deductions, tip treatment, multiple rates, and one-time payments affect the inputs. That is why the exact rule matters more than the title of the calculator.
When the result feels off, do not start by changing the final number. Go back to the start date, paid-hour rule, deduction type, holiday calendar, or pay-rate line and find the input that moved.
Key checks
- Check whether your employer uses weighted average, rate-in-effect, or another approved method.
- If bonuses or differentials are included, they may change the regular-rate calculation.
- Use this as an estimate and compare it with detailed pay-stub lines.
Common mistakes
Key checks
- Do not apply the higher overtime rate to every hour without checking the rule.
- Do not average the two rates without weighting by hours.
- Do not forget that straight time for overtime hours may already be included.
