Free salary with overtime calculator. Calculate total pay, net income, and effective hourly rate when combining regular hours and overtime at 1.5× or 2× rates.
The Salary with Overtime Calculator computes your total annual earnings, per-paycheck take-home, and effective hourly rate when you combine regular hours with overtime work. Enter your base hourly rate, regular and OT hours, and tax rates to see exactly how overtime affects your gross and net pay.
Overtime significantly boosts income — 8 hours of weekly OT at time-and-a-half on a $25/hr base adds $15,600 to annual gross pay. But after taxes, you keep less of OT pay than you might expect because it's taxed at your marginal rate. This calculator provides full transparency into OT economics, showing the tax impact on every additional overtime hour.
The overtime hours impact table is especially useful — it shows exactly how many OT hours you need to reach your income goals, and the paycheck line-item breakdown matches your real pay stub so you can verify each deduction. Check the example with realistic values before reporting.
Overtime can dramatically increase income but is often over-estimated because people forget tax impact. This calculator shows the real after-tax value of each OT hour and helps you plan income targets accurately. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain. Use this clarification to avoid ambiguous interpretation.
Regular Pay = Hourly Rate × Regular Hours × Weeks OT Pay = Hourly Rate × OT Multiplier × OT Hours × Weeks Annual Gross = Regular + OT Pay FICA = min(Gross, $168,600) × 6.2% + Gross × 1.45% Net Annual = Gross − Federal Tax − State Tax − FICA Effective Hourly = Gross ÷ Total Hours
Result: Annual gross: $67,600 | Net per biweekly: $1,907
Regular: $25 × 40 × 52 = $52,000. OT: $25 × 1.5 × 8 × 52 = $15,600. Total: $67,600. After 22% fed + 5% state + FICA: ~$49,580 net. Effective hourly: $27.08.
While OT pays 50% more per hour (at 1.5×), the after-tax value is lower than most expect. On $25/hr, OT pays $37.50/hr gross, but after ~30% total taxes, you net about $26.25 per OT hour. That's still better than the $17.50 net from regular hours, making OT financially worthwhile even after tax.
Diminishing returns kick in when: (1) OT pushes you into a significantly higher bracket (rare for most workers), (2) the time cost outweighs the pay — 60-hour weeks mean less family time and higher burnout risk, (3) if you could spend those hours building a side business or skill with potentially higher long-term return.
While federal law requires 1.5× after 40 hours/week, California mandates: 1.5× after 8 hours/day AND after 40 hours/week, plus 2× after 12 hours/day. This means a CA worker doing four 12-hour days earns: 8 hours regular + 4 hours at 1.5× × 4 days = 48 hours pay for 48 clock hours, vs 40 regular + 8 at 1.5× = 52 hours pay under federal rules (12 OT hours).
No — overtime is taxed at the same marginal rate as regular income. However, since OT adds to total income, it may push you into a higher bracket for the OT portion. The perception of "higher OT tax" often comes from payroll systems estimating higher annualized income from OT checks.
It's your total gross divided by total hours. With 40 regular + 8 OT hours at $25/hr (1.5×), effective hourly is $27.08 — higher than base rate because OT pays more per hour. Net effective hourly is after-tax.
At $25/hr: OT rate = $37.50/hr. 8 hours = $300/week = $15,600/year gross. After ~30% taxes, that's approximately $10,920 net — still a significant income boost.
Yes. OT pay is subject to Social Security tax (6.2%) up to the annual wage base ($168,600 in 2025) and Medicare tax (1.45%) with no cap.
It depends. Non-exempt salaried employees must receive OT pay. Exempt employees (typically earning above the salary threshold of $35,568/year and meeting duty requirements) generally do not qualify for OT.
Double-time pays 2× base rate vs 1.5×. On $25/hr with 8 OT hours: time-and-a-half = $300/week, double-time = $400/week — $5,200 more per year. Some states (CA) require double-time after 12 hours/day.
