Salary Calculator
Use this Salary Calculator to convert pay across common time periods (hourly, weekly, biweekly, semimonthly, monthly, and annual) and to understand how overtime, bonuses, and optional deductions can change the totals.
Pay schedules can be confusing because “biweekly” (26 periods) is not the same as “semimonthly” (24 periods). This tool helps you compare them using standard period counts, so you can plan budgets, compare offers, or sanity-check payroll math.
If you want a broader library of tools, you can browse All Calculators. Net pay estimates here are optional and are meant for planning only, because real withholding varies by individual situation.

How It Works
This Salary Calculator follows a consistent conversion pipeline: it safely parses your inputs, converts your pay into an annual gross using fixed period counts, then computes gross values for every common period. If you enable overtime, the tool treats overtime hours as additional weekly hours and applies your overtime multiplier to those hours.
For optional net pay, you can apply deductions as a percent of gross, a fixed amount per pay period, or a fixed amount per year. You can also add a simplified tax percentage for a planning estimate. If you want to explore more money tools, visit the Finance Calculators hub.
Key assumptions
- Period counts: 52 weeks/year, 26 biweekly periods/year, 24 semimonthly periods/year, 12 months/year.
- Hourly equivalent for non-hourly inputs: 2,080 hours/year (40 hours/week × 52).
- Overtime is modeled as additional hours beyond base hours per week.
- Estimates run locally in your browser; no input data is sent anywhere.
Canonical formulas (general)
Use Cases
- Compare job offers: Convert an hourly wage into an annual salary equivalent (and compare monthly totals for budgeting).
- Budget monthly bills: Translate weekly or biweekly pay into a stable monthly estimate, then plan recurring expenses.
- Plan overtime impact: Model extra overtime hours and see how much they add to weekly and annual gross.
- Choose a pay schedule: Compare biweekly vs semimonthly totals to understand why the paycheck amount can differ even with the same annual pay.
- Estimate take-home pay: Add a simple deductions model (and an optional tax estimate) to get a quick net pay planning range.
Common Mistakes
- Mixing gross and net amounts when comparing offers or budgets.
- Assuming biweekly and semimonthly are the same schedule (26 vs 24 pay periods).
- Ignoring overtime as additional hours and accidentally replacing base hours instead.
- Entering annual salary as a “monthly” amount (or vice versa), which multiplies incorrectly.
- Using an unrealistic hours-per-week number for hourly conversions, which inflates annual totals.
Quick Tips
- If you’re hourly, set hours per week to your real average (not just your scheduled hours).
- Use overtime only for hours that are truly paid at the overtime multiplier.
- For bonuses, pick the correct timing so annualization matches how you’re paid.
- If you enable net pay, treat tax as a planning percentage, not a precise paycheck prediction.
- When negotiating, compare annual gross first, then compare monthly net estimates for lifestyle impact.
If you’re specifically modeling how a pay increase changes your totals, the salary raise calculator can help you compare before-and-after pay.
Examples
Example 1: Hourly with overtime
Inputs: Hourly rate $28.00, hours per week 40, overtime enabled with 6 overtime hours at 1.5×. The tool treats overtime as additional hours and computes weekly gross first, then annualizes it using 52 weeks.
| Output | Value (approx.) | Why |
|---|---|---|
| Weekly gross | $1,330.00 | $28×40 + $28×6×1.5 |
| Annual gross | $69,160.00 | Weekly × 52 |
| Monthly gross | $5,763.33 | Annual ÷ 12 |
Example 2: Annual salary with bonus
Inputs: Annual pay $90,000 with an annual bonus of $7,500. The calculator adds the bonus to annual gross, then shows the implied monthly and per-paycheck amounts.
| Output | Value (approx.) | Why |
|---|---|---|
| Annual gross (with bonus) | $97,500.00 | $90,000 + $7,500 |
| Biweekly gross | $3,750.00 | Annual ÷ 26 |
| Semimonthly gross | $4,062.50 | Annual ÷ 24 |
Example 3: Biweekly vs semimonthly comparison
Suppose you see a gross paycheck of $2,800. If that’s biweekly, annual gross is $2,800×26 = $72,800. If it’s semimonthly, annual gross is $2,800×24 = $67,200. Same paycheck size, different schedule.
| Schedule | Pay periods | Annual gross (approx.) |
|---|---|---|
| Biweekly | 26 | $72,800.00 |
| Semimonthly | 24 | $67,200.00 |

FAQ
What is a Salary Calculator used for?
A Salary Calculator converts pay between common time periods so you can compare offers, budget, or sanity-check payroll math. You can start with an hourly wage, a weekly paycheck, a biweekly amount, a semimonthly amount, a monthly salary, or an annual salary. The tool converts that input into an annual gross using standard period counts, then shows the gross pay for every other period. Optional features like overtime, bonuses, and deductions help you model realistic scenarios when you want a planning view beyond a simple conversion.
What’s the difference between biweekly and semimonthly pay?
Biweekly pay happens every two weeks, which creates 26 pay periods per year. Semimonthly pay happens twice per month, which creates 24 pay periods per year. That difference matters because the same annual salary will produce a smaller biweekly paycheck than a semimonthly paycheck, since the money is spread across more paychecks. Conversely, a fixed paycheck amount produces a higher annual total if it is biweekly rather than semimonthly. This calculator uses standard counts (26 vs 24) to keep comparisons consistent.
How does the calculator handle overtime?
Overtime is modeled as additional hours beyond your base hours per week. For hourly pay, the calculator computes a regular weekly gross (hourly rate × base hours) and an overtime weekly gross (hourly rate × overtime hours × overtime multiplier). It then adds them to form a total weekly gross and annualizes it using 52 weeks. If your overtime is paid differently (for example, blended rates or varied schedules), you can still use the overtime controls to approximate impact, but treat the result as an estimate based on the inputs you provide.
How are bonuses or extra pay treated?
You can include a bonus as either an annual amount or a per-pay-period amount. An annual bonus is added directly to annual gross. A per-pay-period bonus is multiplied by the number of pay periods for your selected pay basis to convert it into an annual bonus. For example, a $200 per biweekly period bonus is annualized as $200 × 26. If your selected pay basis is hourly, the per-period bonus is treated as weekly for annualization. After the bonus is annualized, the tool recomputes every period’s gross from the updated annual total.
How accurate is the net pay estimate?
The net pay estimate is a planning tool, not a paycheck guarantee. Real take-home pay depends on factors this calculator does not model, such as tax brackets, credits, pre-tax benefits, local rules, and payroll-specific withholding methods. The calculator lets you apply optional deductions (percent of gross or fixed amounts) and an optional simplified tax percentage to create an estimated net. Use it to understand ranges and tradeoffs, like how changing a deduction rate affects monthly take-home pay. If you need exact results, compare against a real pay stub or payroll provider calculation.
What do “deductions” mean in this calculator?
Deductions in this calculator represent any withholdings you want to model, such as benefits, retirement contributions, or other recurring subtractions from gross pay. You can set deductions as a percent of gross (for proportional planning), a fixed amount per pay period (for predictable recurring deductions), or a fixed amount per year (for annualized costs). The calculator annualizes your chosen deduction method, combines it with an optional simple tax estimate, and then computes net pay by period. If your deductions are pre-tax or vary by period, treat the result as a simplified estimate.
How do I convert hourly pay to an annual salary?
For hourly inputs, the calculator uses hours per week and 52 weeks per year to estimate annual gross. The basic conversion is hourly rate × hours per week × 52. If overtime is enabled, overtime hours are treated as additional weekly hours and are multiplied by the overtime multiplier before annualization. This method provides a consistent annual estimate for planning and offer comparisons. If your work schedule is seasonal, includes unpaid time off, or has variable hours, you can adjust the hours per week to reflect a realistic average so the annual estimate better matches your typical year.
How does rounding work for currency values?
The calculator displays currency values rounded to 2 decimals to match common payroll and budgeting conventions. Internally, it keeps intermediate calculations at higher precision (up to 6 decimals) to reduce drift when converting between periods. For example, annual totals are computed first, then each period amount is derived from the annual figure using standard period counts. This approach helps keep the breakdown consistent, even if some period conversions create repeating decimals. If you need to reconcile with a payroll system, minor differences can occur because employers may round at different stages of their calculation pipeline.
What assumptions does the Salary Calculator use?
This calculator uses standard pay period assumptions to keep conversions consistent: 52 weeks per year, 26 biweekly periods, 24 semimonthly periods, and 12 months per year. For non-hourly inputs, an hourly “equivalent” is shown using 2,080 hours per year (40 hours per week × 52) as a reference point. Overtime is modeled as additional hours beyond base hours, paid at the entered overtime multiplier. Net pay is optional and uses simplified deductions and an optional simple tax percentage for planning only. All calculations run locally in your browser.
