How do I calculate overtime pay correctly?
Overtime rules in the US can be simple—once you know which employees are eligible and what counts as “hours worked.” This guide explains the basics and how a payroll service can calculate it reliably; RunWise Pay is a free match, not a payroll provider.
First: what overtime usually means (and when it applies)
In most US workplaces, overtime means paying certain employees 1.5× their regular hourly rate for hours worked over 40 in a workweek. A “workweek” is a fixed 7-day period you choose (for example, Monday–Sunday), and it stays the same every week.
Not everyone gets overtime. Some roles are exempt (not paid overtime even if they work long hours) and some employees may be covered by special rules. If you’re unsure whether an employee is “exempt” or “non-exempt,” confirm that classification with a qualified payroll provider or an employment attorney/accountant.
This guide is general information only. Payroll rules, thresholds, and deadlines can vary by state and change over time, so use this as a starting point—not legal or tax advice.
- Typical baseline: 1.5× regular rate for hours over 40 in the same workweek
How to calculate overtime pay step-by-step (simple method)
Use this basic method for “non-exempt” employees covered under the federal overtime rule.
1. Figure out the employee’s regular hourly rate for the overtime calculation.
2. Count total “hours worked” in the workweek (from your time records).
3. Identify overtime hours: any hours over 40 in that workweek.
4. Calculate overtime pay: overtime hours × (regular hourly rate × 1.5).
5. Add it to regular pay for the same workweek.
Key watch-out: overtime is based on the workweek total, not on daily totals. Two 10-hour days do not automatically equal overtime unless the week total exceeds 40.
What can make overtime calculations tricky (and where mistakes happen)
Even when the overtime rule is “hours over 40,” the calculation can get complicated depending on how you pay people.
- Different pay types: Employees paid hourly, salaried, or partly on bonuses/commissions may have a different “regular rate” for overtime purposes.
- Premiums and allowances: Some payments are treated differently for overtime calculation than others.
- Time records: The definition of “hours worked” can include/exclude certain time (like breaks, travel, or on-call time) depending on the situation and state rules.
- State rules: Some states require overtime under additional conditions (for example, daily overtime or different thresholds).
If you want to reduce risk, use consistent timekeeping, confirm the employee’s overtime status, and keep a paper trail of how time was recorded and how pay was calculated.
- Overtime is usually based on weekly totals, but “regular rate” and “hours worked” can vary
What a payroll service should do for you (so you’re not guessing)
Because overtime can be nuanced, many owners outsource payroll calculations. A good payroll service should be able to:
- Run each pay period using your hours/time entries.
- Calculate overtime automatically using the correct overtime rules.
- Produce clear pay statements showing regular pay and overtime pay lines.
- Help with year-end forms (W-2 and 1099 where applicable).
- Keep you organized for compliance tasks like filings and reporting.
RunWise Pay is a FREE matching service—not a payroll provider. We connect you with payroll service providers that can handle payroll tasks like overtime calculations, tax filing, and payment by direct deposit. The real cost depends on team size, pay frequency, your state, and what’s included—so ranges are not quotes.
Typical provider pricing often looks like a base monthly fee plus a per-employee fee (for example, a few hundred dollars per month total for small teams can be common, and it can be higher or lower depending on services and state). Confirm the exact monthly cost and all fees in writing before you sign anything.
Payroll red flags to avoid (especially for overtime)
If you’re switching providers or setting up payroll for the first time, watch for these warning signs. They often lead to payroll errors, surprise costs, or stressful corrections later.
- Vague pricing: “Low starting cost” without a clear breakdown of per-employee fees, timekeeping fees, or add-on costs.
- Hidden charges: extra fees for tax forms, amendments, support, or integrations.
- No tax-filing or correction clarity: if they won’t say how they handle mistakes, you need to ask directly.
- Poor support: long delays when you have a payroll question, especially during the pay week.
- Pressure to sign fast: a rushed sales process can hide important details.
Before you hire anyone, confirm what’s included in writing—specifically overtime calculation support, how they handle time entries, what reporting you’ll receive, and what the total cost will be for your situation.
How RunWise Pay can help you get the right overtime support
If you want overtime calculated correctly without doing the math yourself, the next step is to match with a payroll service provider that fits your needs.
