Annual Income Calculator

Add up every income source — a salary, a side job, freelance work, rent — into one annual and monthly figure.

Add an amount to any income source to see your total for the year.

Exact calculation. Given your inputs, this is the answer — no estimation involved.

How this calculator works

Each source is annualized on its own terms and then summed. An hourly side job is multiplied by its hours and weeks; a monthly rent payment by twelve; a one-off bonus is added once.

Recurring pay uses calendar counts, not approximations: 26 biweekly paychecks a year, 24 semi-monthly, 12 monthly, 4 quarterly. This matters because 26 biweekly paychecks is not the same as 24 semi-monthly ones, even at the same annual salary.

The result is gross income — the figure a lender, a landlord or a benefits application asks for. It is before tax.

The formula

Exactly what happens to your numbers, step by step.

Hourly sources

annual = rate × hours per week × weeks per year

Recurring sources

weekly    × weeks worked
biweekly  × 26
semi-monthly × 24
monthly   × 12
quarterly × 4

Total

total annual = sum of every annualized source
monthly = total ÷ 12

A worked example

A $60,000 salary, a weekend job at $20 an hour for 10 hours a week, and $500 a month from a rental.

What you enter

Main job: $60,000 a year
Second job: $20/hour, 10 h/week, 52 weeks
Rental income: $500 a month

Step by step

Main job: $60,000
Second job: 20 × 10 × 52 = $10,400
Rental: 500 × 12 = $6,000
Total: $76,400

Total annual income: $76,400 — about $6,367 a month

The side income adds 27% on top of the salary. If you are applying for a mortgage, lenders usually want two years of history before counting income from a second job or a rental.

Assumptions

Every result here rests on these. Change your inputs and the result changes with them.

All figures are gross, before tax and deductions.
Income is assumed steady across the year. Seasonal or variable work should be entered as an annual total instead.
One-time amounts are counted once, in this year only.

What this cannot tell you

It does not distinguish income a lender will count from income they will not. Most lenders want two years of history for self-employment, bonuses and rental income.
Self-employment income here is gross revenue, not net profit after business expenses.

Questions people ask

Should I use gross or net income?

Enter gross — the amount before tax. Almost everything that asks for your annual income, including loan applications and rental applications, means gross. Use the Paycheck Calculator to see the take-home equivalent.

How do I handle irregular freelance income?

Total what you actually earned over the last twelve months and enter it as a single annual amount. Annualizing a good month overstates the year.

Does this include my spouse’s income?

Only if you add it. For a joint mortgage application, add each person’s income as a separate source so the total reflects the household.

How do I work out my gross annual income from a paycheck?

Take the pay before any taxes or deductions come out, which is the gross figure on your pay stub, and multiply it by the number of paychecks in a year: 52 if weekly, 26 if every two weeks, 24 if twice a month, 12 if monthly. $2,000 every two weeks is $52,000 a year. Bonuses, overtime and side income are not in a regular paycheck, so add them as separate sources.
