About the Required Income Calculator
This required income calculator answers a simple but important question: how much do I need to earn? Enter what you spend each month on housing, utilities, food, transport, insurance, debt payments and everything else, add the amount you want to save, then enter your effective tax rate and any pre-tax retirement contribution. The calculator works backwards from the take-home pay you need to the gross salary that produces it, and converts that into a monthly and hourly figure.
It is useful when you are negotiating a job offer, deciding whether you can afford to move to a more expensive city, planning a career change, or setting a target before going freelance. Because it starts from your real costs rather than a rule of thumb, it shows the salary that actually funds your life — including the savings that many quick estimates leave out.
Taxes are modelled with a single effective rate applied to gross pay. Use your all-in rate (federal or national income tax, state or local tax, and payroll or social-security taxes combined) — you can find it by dividing last year’s total tax by your gross income. Pre-tax retirement contributions such as a 401(k) are taken from gross pay before your take-home amount.
With the default inputs, the gross annual income needed is $82,192. Change any value above to recalculate instantly.
How to use the required income calculator
- 1Enter your monthly costs for each spending category — use bank statements for accuracy.
- 2Add how much you want to save each month after tax.
- 3Enter your effective tax rate (total tax ÷ gross income from last year’s return).
- 4Add any pre-tax retirement contribution percentage and your weekly hours.
- 5Read the gross salary and hourly wage you need, then check the breakdown chart.
Formula and method
The calculator first adds your monthly expenses (E) and after-tax savings goal (S) to get the take-home pay you need. Gross pay must cover that amount plus taxes and any pre-tax retirement contribution, and both of those are a percentage of gross pay. So the yearly take-home amount is divided by the share of gross pay you keep, 1 − t − r.
For example, with a 22% effective tax rate and a 5% 401(k) contribution you keep 73% of each gross dollar, so every $1 of take-home pay requires about $1.37 of salary. The hourly figure assumes 52 paid weeks a year; if you take unpaid time off, divide by fewer weeks. A single effective tax rate is a simplification — progressive brackets mean your marginal rate on a raise is higher than your average rate.
- E
- Total monthly living expenses, including debt payments
- S
- Monthly after-tax savings goal
- t
- Effective (average) tax rate on gross income
- r
- Pre-tax retirement contribution rate
Worked examples
$5,000 a month take-home with 22% tax and 5% to a 401(k)
Expenses of $4,200 plus $800 savings means you need $5,000 a month, or $60,000 a year, in take-home pay. You keep 73% of gross after 22% tax and a 5% 401(k), so $60,000 ÷ 0.73 = $82,192 a year, about $39.52 an hour over 2,080 hours. Taxes come to about $18,082.
Single renter in a cheaper city, no retirement contribution
Monthly costs of $2,680 plus $400 savings total $3,080 take-home, or $36,960 a year. Dividing by 0.82 (keeping 82% after an 18% tax rate) gives about $45,073 a year, or $21.67 an hour, with $8,113 going to tax.
Family budget, 28% tax, 10% retirement, 45-hour weeks
This household needs $9,000 a month take-home ($108,000 a year). With 28% tax and 10% retirement it keeps 62% of gross, so it needs $108,000 ÷ 0.62 ≈ $174,194 a year, of which $17,419 goes to retirement. At 45 hours a week for 52 weeks that is about $74.44 an hour.
Frequently asked questions
How much do I need to earn to live comfortably?+
It depends entirely on your costs. A practical definition of “comfortable” is a salary that covers all expenses and still lets you save 15–20% of income. Enter your real spending plus a savings goal here and the calculator returns the gross pay that achieves it.
What is an effective tax rate and how do I find mine?+
Your effective rate is total tax paid divided by gross income — your average rate, not your top bracket. Add income tax, state or local tax and payroll taxes from last year’s return and pay stubs, then divide by gross pay. US employees should include FICA: 6.2% Social Security (on wages up to $184,500 in 2026) plus 1.45% Medicare, or 7.65% in total for most workers.
Should I include retirement savings as an expense or a percentage?+
Put pre-tax workplace contributions such as a 401(k) or pension in the retirement percentage, because they come out before tax. Put after-tax saving — a Roth IRA, emergency fund or brokerage account — in the monthly savings goal.
How do I convert the annual salary to an hourly wage?+
Divide the yearly figure by hours per week times 52. At 40 hours a week that is 2,080 hours, so a $62,400 salary equals $30 an hour. If you expect unpaid weeks off, freelancers should divide by fewer weeks and add a margin for unbilled time.
Why is the required salary so much higher than my expenses?+
Every dollar you spend has to be earned before tax. If you keep 73 cents of each gross dollar, you need about $1.37 of salary for each dollar of spending or saving, so taxes and retirement contributions add roughly a third on top of your take-home needs.
