Everything routes through the annual figure
To get a monthly number from any pay period, first turn it into an annual total, then divide by 12. That one step avoids the errors that come from treating a month as exactly four weeks or two paychecks.
| You're paid | Monthly income |
|---|---|
| Per year | annual ÷ 12 |
| Per hour | hourly × hours × 52 ÷ 12 |
| Per week | weekly × 52 ÷ 12 |
| Every two weeks | biweekly × 26 ÷ 12 |
| Twice a month | semi-monthly × 2 |
Salary to monthly
| Annual | Monthly gross | Monthly net* |
|---|---|---|
| $30,000 | $2,500 | ~$2,100 |
| $40,000 | $3,333 | ~$2,750 |
| $50,000 | $4,167 | ~$3,400 |
| $60,000 | $5,000 | ~$4,000 |
| $75,000 | $6,250 | ~$4,900 |
| $100,000 | $8,333 | ~$6,400 |

Hourly to monthly (40 hours a week)
| Hourly | Monthly gross |
|---|---|
| $10 | $1,733 |
| $15 | $2,600 |
| $20 | $3,467 |
| $25 | $4,333 |
| $30 | $5,200 |
| $50 | $8,667 |
The 173.33 comes from 40 × 52 ÷ 12. Multiplying by 160 (four weeks) undercounts, because most months run slightly over four weeks.
The mistakes that skew the number
- Biweekly is not twice a month. 26 paychecks a year, not 24, so use ×26 ÷12.
- Hourly is not ×160. Use ×173.33; the four-week shortcut loses roughly a week of pay a year.
- Lenders want gross. Mortgage and rent affordability (the debt-to-income ratio) is figured on gross monthly income, not take-home.
- Irregular pay averages out, months don't. Bonuses, commission and overtime raise the yearly average without landing evenly each month.
Common questions
How do I work out my monthly income from an annual salary?
Divide the annual figure by 12. A $60,000 salary is $5,000 per month gross.
How do I convert an hourly wage to monthly income?
Multiply the hourly rate by hours per week, then by 52, then divide by 12. At 40 hours a week that is the same as multiplying by 173.33. So $20 per hour is about $3,467 per month.
Why does multiplying biweekly pay by 2 give the wrong answer?
A biweekly cycle pays 26 times a year, not 24, so two paychecks do not equal a month. Multiply biweekly pay by 26 and divide by 12 instead.
What is the difference between gross and net monthly income?
Gross is before deductions. Net is what lands in your account after federal tax, any state tax, Social Security (6.2%) and Medicare (1.45%). Net is usually 65 to 80% of gross.
