Content updated: 2026-10-21

The core formula

At 25 per hour, 40 hours per week and 48 working weeks, gross annual pay is 48,000. Assuming 52 paid weeks instead would overstate income if unpaid leave is included.

Annual from Hourly = Hourly Rate × Hours/Week × Weeks/Year

Worked example

$30 × 40 × 52 = $62,400 annual gross income.

How to annualize pay

  1. Choose the pay frequency you actually receive: hourly, daily, weekly, biweekly or monthly.
  2. For hourly pay, multiply the hourly rate by paid hours per week and paid working weeks per year.
  3. For weekly or biweekly pay, multiply by the number of pay periods in the year.
  4. For monthly pay, multiply regular monthly pay by 12 and add recurring bonuses only if you intend to include them.

Gross annual income vs take-home income

Annualized income is usually a gross figure before income tax, pension deductions, insurance and other payroll deductions. It is useful for comparing pay structures, but it is not the same as cash received in your bank account.

Irregular overtime, unpaid leave, commissions and bonuses can make a simple annualization too high or too low. Use expected paid hours and realistic pay periods when income changes during the year.

Common mistakes

  • Using 52 paid weeks when some weeks are unpaid.
  • Mixing net take-home pay with gross salary figures.
  • Treating a one-time bonus as recurring annual compensation.

How do I annualize hourly pay?

Multiply hourly rate by paid hours per week and paid working weeks per year.

What should I verify about gross pay does not equal take-home pay?
