How to use the monthly income calculator
- Add each income source and how often it's paid: per hour, weekly, every two weeks, twice a month, monthly, quarterly or yearly.
- For hourly pay, enter your hours a week.
- Set an estimated tax and deduction rate to see take-home income. Use 0 for income that's already after tax.
How to convert any pay to monthly income
| You're paid | Monthly income = |
|---|---|
| Hourly | rate × hours a week × 52 ÷ 12 |
| Weekly | pay × 52 ÷ 12 (× 4.33) |
| Every two weeks | pay × 26 ÷ 12 (× 2.17) |
| Twice a month | pay × 2 |
| Monthly | pay |
| Quarterly | pay ÷ 3 |
| Yearly | pay ÷ 12 |
A common mistake is multiplying weekly pay by 4. A month has about 4.33 weeks, so a $1,000 weekly paycheck is $4,333 a month, not $4,000. Over a year that's $4,000 of income you didn't plan for.
The same income in every period
For the example above, $4,933 a month gross:
| Period | Gross |
|---|---|
| Yearly | $59,200 |
| Monthly | $4,933 |
| Twice a month | $2,467 |
| Every two weeks | $2,277 |
| Weekly | $1,138 |
| Per working day | $228 |
| Per hour (40 h a week) | $28.46 |
Gross vs net monthly income
Gross income is before tax and deductions; net is what reaches your bank. Lenders use gross income: the 28/36 rule keeps housing at 28% and all debt payments at 36% of gross income, and many landlords want gross income of three times the rent. Check yours with the debt-to-income ratio calculator and the rent affordability calculator.
For your own budget, always start from net income. Taxes, Social Security, Medicare, health insurance and 401(k) contributions usually take 20–30% of gross pay. The take-home pay calculator works out the exact figure for a paycheck.
Three-paycheck months
If you're paid every two weeks, two months a year have three paychecks. Budget on two paychecks a month and use the third ones for savings, debt or sinking funds. It's an easy way to save two extra paychecks a year without feeling it.
Irregular and side income
Freelance, gig and side-hustle income changes from month to month. Average the last 12 months, but build your monthly budget on a low month. Put the extra from good months into a buffer, then into your emergency fund. If you're self-employed, set aside tax from every payment; the 1099 tax calculator shows how much.
Turn your monthly income into a plan
Once you know your monthly take-home, give every dollar a job with the monthly budget calculator, and see your hourly value with the salary to hourly calculator.
Budget around real paydays
Flow is a budget planner that plans each paycheck as it arrives, including three-paycheck months and irregular income, and shows what's safe to spend. Vault keeps income, bills, savings and debt on one dashboard. Both have a free demo with sample data.
