Convert Hourly Wage to Monthly Salary — The Basics

This guide explains how to turn an hourly wage into an approximate monthly salary. The calculation is based on gross pay (before taxes and deductions) so that it remains region-neutral. Actual take-home pay will vary depending on working days, overtime, allowances, and local rules.

Common Calculation Methods

The key to converting an hourly rate is deciding how many hours per month to assume. Two widely used approaches are:

  1. Weekly-based method
    Monthly salary = Hourly wage × Weekly hours × 52 ÷ 12
    Uses the average of about 4.33 weeks per month for a balanced annual conversion.
  2. Day-based method
    Monthly salary = Hourly wage × Daily hours × Working days per month
    Better if you want to account for the exact number of workdays each month.

Assumptions That Improve Accuracy

  • Weekly hours: for example, 20, 30, or 40 hours
  • Overtime or premiums: add separately if applicable
  • Holidays or unpaid leave: weekly-based averages smooth this out, but major breaks need adjustment
  • Allowances: fixed monthly allowances should be added on top
  • Deductions: these examples show gross pay, not net (take-home)

Worked Examples

Example 1 — Full-time

Hourly wage = 20, weekly hours = 40, weekly-based method

Monthly salary = 20 × 40 × 52 ÷ 12
               ≈ 20 × 173.33
               ≈ 3,466.67

Example 2 — Part-time

Hourly wage = 15, weekly hours = 24

Monthly salary = 15 × 24 × 52 ÷ 12
               ≈ 15 × 104.00
               ≈ 1,560.00

Example 3 — Day-based

Hourly wage = 18, daily hours = 6, working days = 22

Monthly salary = 18 × 6 × 22
               = 2,376

Quick Reference Table (Weekly-based)

Assuming an average of 4.33 weeks per month:

Hourly wage 20 hours/week 30 hours/week 40 hours/week
10 ≈ 867 ≈ 1,300 ≈ 1,733
15 ≈ 1,300 ≈ 1,950 ≈ 2,600
20 ≈ 1,733 ≈ 2,600 ≈ 3,467
25 ≈ 2,167 ≈ 3,251 ≈ 4,335

Overtime and Premiums

If overtime applies, add it to the base calculation:

Base monthly = Hourly × Base hours (weekly × 52 ÷ 12)
Overtime     = Hourly × Premium rate × Overtime hours
Total        = Base monthly + Overtime

Annual Salary Perspective

A simple way to estimate annual salary is monthly × 12. To include bonuses or other irregular income, add them separately. Another way is hourly × total annual hours.

Tips for Input

  • Use actual worked hours (exclude breaks)
  • If hours vary, average over the last 3–6 months
  • Add fixed monthly allowances separately
  • For net pay, subtract taxes and deductions afterward

Frequently Asked Questions

Why use 4.33 weeks per month?

Because there are 52 weeks in a year and 12 months, which averages to about 4.33 weeks per month.

How can I estimate take-home pay?

Start with the gross monthly amount, then subtract taxes, insurance, and other deductions based on local rules.

What if my weekly hours change often?

Use an average of several months, or calculate separately for each month and then average them.

Where do fixed allowances fit?

Add them to the converted monthly salary after the base calculation. For variable allowances, use a past average.
