Salary Calculator

by

Convert your pay between hourly, weekly, biweekly, semimonthly, monthly, and annual amounts using your own work schedule. You can also include overtime and get a simple take-home pay estimate using an effective tax rate and per-paycheck deductions.

Pick the number you already have (for example, an hourly wage or an annual salary). The calculator converts it to the other pay periods.
Enter your pay before taxes and deductions for the pay type you selected.
Typical hours you work in a week. This is used to convert hourly pay to salary, and to compute an hourly equivalent for salary.
How many weeks you get paid in a year. Use 52 if you are paid all year, or a smaller number if you have unpaid weeks.
Used to show daily pay and working days per year. If you do not have a steady schedule, use a reasonable average (for example, 8).
Advanced options
Overtime and unpaid time
Choose Yes if you regularly work overtime and want it included in the totals.
Average overtime hours per week. Count only the hours paid at the overtime rate.
Enter the total overtime rate multiplier. Use 1.5 for time-and-a-half and 2.0 for double-time. If your payroll describes only a 0.5 premium, enter 1.5 here.
If you take unpaid time off (or your job is seasonal), enter how many weeks you are not paid. The calculator will use paid weeks = weeks per year minus unpaid weeks.
Net (take-home) estimate
Choose Yes to estimate net pay using a simple effective tax rate plus optional deductions. This is an estimate, not a tax filing result.
A simple estimate of total taxes as a percent of gross pay (for example, 20%). Leave net mode off if you are unsure.
Deductions taken out before taxes, per paycheck in the pay period shown (for example, 401(k) contributions if treated pre-tax). For a simple approach, keep this at 0.
Deductions taken out after taxes, per paycheck (for example, wage garnishments or some insurance payments).
Display
Controls how money values are rounded for display only. Calculations use full precision internally.
Enhancements
When net mode is enabled, choose your real paycheck frequency. This controls how per-paycheck deductions are annualized and how take-home per paycheck is shown. For annual or hourly pay basis, this selection is required.
Many sites assume 2,080 hours per year (40 hours/week x 52 weeks). Turn this on to see what your gross pay would be under that standard assumption, for easier comparison.
Full keeps full precision for all intermediate calculations (recommended). Rounding intermediate values can make the outputs match some payroll systems but may introduce small differences.
Annual gross pay
Your total pay before taxes and deductions for the year, based on your inputs and assumptions.
Monthly gross pay (12 per year)
Annual gross divided by 12. This is a budgeting view, not necessarily your paycheck amount.
Semi-monthly gross pay (24 per year)
Annual gross divided by 24 (two paychecks per month).
Biweekly gross pay (26 per year)
Annual gross divided by 26 (every 2 weeks).
Weekly gross pay (52 per year)
Annual gross divided by 52.
Daily gross pay
Paid-week gross divided by working days per week, based on hours per day and hours per week.
Hourly equivalent (gross)
Annual gross divided by (paid weeks per year x hours per week).
Paid hours per year
Paid weeks per year x hours per week.
Paychecks per year (by pay period)
Shows the convention used: weekly=52, biweekly=26, semimonthly=24, monthly=12.
Annual overtime pay (if enabled)
Overtime pay added on top of regular pay, based on overtime hours per week and overtime multiplier.
Annual take-home pay estimate (if enabled)
Estimated net pay using your effective tax rate and deductions settings.
Take-home pay per paycheck estimate (if enabled)
Estimated net per paycheck in the selected pay period view.

How to use our Salary Calculator

  1. Choose I know my pay as (hourly, weekly, biweekly, semimonthly, monthly, or annual salary).
  2. Enter the Gross pay amount (USD) for that pay type (gross means before taxes and deductions).
  3. Enter Hours worked per week and Paid weeks per year to match your real schedule (for example, 40 and 52).
  4. Enter Hours worked per day to estimate daily pay and working days per week (for example, 8).
  5. Open Advanced options if you want to include overtime, unpaid weeks, or take-home pay.
  6. If using overtime, set Include overtime? to Yes, then enter overtime hours per week and the overtime multiplier (often 1.5).
  7. If you have unpaid time off, enter Unpaid weeks per year so the calculator uses paid weeks = weeks per year minus unpaid weeks.
  8. If estimating take-home pay, set Estimate take-home pay? to Yes, then enter your Effective tax rate and any pre-tax or post-tax deductions per paycheck.
  9. Pick a Rounding for display option if you want (this changes only how results are shown).
  10. Click Calculate to see gross pay by each pay period, hourly equivalent, paid hours per year, and optional net estimates.

Definitions

Gross pay: Your pay before any taxes or deductions are taken out.

Net pay (take-home pay): What you keep after taxes and deductions.

Pay period: How often you get paid. Common conventions are weekly (52 per year), biweekly (26), semimonthly (24), and monthly (12) [1].

Biweekly vs semimonthly: Biweekly means every 2 weeks (26 checks/year). Semimonthly means twice per month (24 checks/year) [1].

Hours worked per week: Your typical weekly hours, used to convert between hourly and annual pay.

Paid weeks per year: Weeks you are paid during the year. If you have unpaid weeks, paid weeks = weeks per year minus unpaid weeks.

Hourly equivalent: The hourly rate that would produce the same annual gross pay, based on your hours per week and paid weeks per year.

Overtime multiplier: How much more overtime hours pay compared to regular hours (for example, 1.5 means time-and-a-half).

Effective tax rate: A single percent you choose to approximate total taxes as a share of gross pay (used only when take-home mode is on).

Methodology

Pay period conventions

This calculator uses standard counts per year:

weekly = 52, biweekly = 26, semimonthly = 24, monthly = 12 [1].

Step 1: Compute paid weeks

paid_weeks = weeks_per_year - unpaid_weeks_per_year

If paid weeks is 0 or less, the calculator shows an error because annual totals would not make sense.

Step 2: Convert your input to base annual gross

If you enter hourly pay, the amount is treated as an hourly rate.

annual_base = hourly_rate * hours_per_week * paid_weeks

If you enter an annual salary, it is already annual.

annual_base = annual_salary

If you enter a weekly, biweekly, semimonthly, or monthly amount, it is multiplied by the pay periods per year for that frequency [1].

annual_base = period_amount * periods_per_year

Step 3: Optional overtime (estimate)

When overtime is enabled, overtime pay is estimated using an hourly rate. If you started with salary, the hourly rate is computed from your base annual amount and schedule.

hourly_equiv = annual_base / (hours_per_week * paid_weeks)

annual_overtime = hourly_equiv * ot_multiplier * ot_hours_per_week * paid_weeks

annual_gross = annual_base + annual_overtime

Step 4: Convert annual gross to each pay period

period_gross = annual_gross / periods_per_year

The calculator reports monthly (12), semimonthly (24), biweekly (26), and weekly (52) views even if your employer pays differently.

Step 5: Hourly, daily, and time totals

hourly_equiv_gross = annual_gross / (hours_per_week * paid_weeks)

paid_hours_per_year = hours_per_week * paid_weeks

days_per_week = hours_per_week / hours_per_day

daily_gross = weekly_gross / days_per_week

If hours per day is not greater than 0, daily values are shown as N/A because days per week cannot be computed safely.

Step 6: Optional take-home (net) estimate

Net mode uses a simple effective-rate model. This is meant for quick budgeting, not exact payroll withholding.

tax_rate = effective_tax_rate_percent / 100

annual_pretax_ded = pretax_deductions_per_paycheck * periods_per_year

annual_posttax_ded = posttax_deductions_per_paycheck * periods_per_year

annual_net = annual_gross - (annual_gross * tax_rate) - annual_pretax_ded - annual_posttax_ded

net_per_paycheck = annual_net / periods_per_year

If the net estimate is negative, the calculator still shows it and also warns you that your tax rate and deductions add up to more than your gross pay.

Rounding and display

Rounding affects display only. Internally, calculations use full precision and money outputs are formatted with commas.
