Pay Calculator: Tips & How-Tos

Best Practices

Confirm whether your rate is pre-tax or post-tax. Hourly rates quoted by employers are almost always gross (pre-tax). Confirm this before entering into the calculator — entering a net rate will produce an inaccurate annual gross.
Annual salary ÷ 2,080 = hourly rate for a 40-hour week. A standard full-time work year is 52 weeks × 40 hours = 2,080 hours. Use this to cross-check the calculator's output or to quickly estimate hourly rates from salary offers.
Biweekly paychecks total 26 per year, not 24. Biweekly pay (every two weeks) produces 26 paychecks per year. Semi-monthly pay (twice a month) produces 24. The annual totals are the same, but the individual paycheck amounts differ.
Overtime typically starts after 40 hours in the US. Federal law requires 1.5× pay for hours worked beyond 40 in a single workweek. Some states (California, for example) also require daily overtime after 8 hours. Check your state's rules.
Self-employed workers pay both halves of FICA. Employees pay 7.65% in FICA (Social Security + Medicare); employers match this. Self-employed workers pay the full 15.3% as self-employment tax before income tax.

The calculator gives a rough estimate, not an exact tax. Actual withholding depends on your W-4 elections, filing status, deductions, and other income. The estimate is a useful planning figure, not a substitute for professional tax advice.
Federal income tax uses brackets, not a flat rate. Each dollar of income is taxed only at the rate for its bracket. Earning $1 more does not tax all your income at the higher rate — only that extra dollar crosses into the new bracket.
State income tax ranges from 0% to over 13%. Nine US states have no income tax; California's top rate exceeds 13%. The calculator's tax estimate uses federal rates; add your state rate separately for a full picture.
Pre-tax benefits reduce your taxable income. 401(k) contributions, health insurance premiums, and HSA contributions reduce your taxable gross income. The take-home estimate improves further if you contribute to these pre-tax accounts.

Compare annual salary, not hourly rate alone. A job with a lower hourly rate but guaranteed 45 hours per week may pay more annually than a higher-rate job with only 35 hours. Always convert to annual totals before comparing offers.
Include employer benefits in total compensation. Health insurance, 401(k) matching, PTO, remote work savings, and bonuses are all compensation. A $60K job with full benefits can easily outvalue a $70K job with none.
Account for cost-of-living differences. A $90K salary in San Francisco buys significantly less than $90K in a mid-sized city. Use a cost-of-living index to normalise salaries when comparing offers in different locations.
Remote work saves $5,000–$15,000 per year on average. Commuting costs, work clothing, and lunches can total several thousand dollars annually. A remote position at the same nominal salary is effectively worth more in take-home value.

Converting an hourly rate to an annual figure for budgeting or job comparison.

Putting salary-based and hourly offers on the same footing.

For the hourly offer: enter the rate and expected hours per week in the calculator to get an annual gross figure.
For the salaried offer: divide the annual salary by 2,080 to get an equivalent hourly rate.
Compare both annual figures side by side.
Factor in overtime eligibility (hourly workers often get overtime; salaried exempt workers often do not).
Add the estimated value of each offer's benefits package before making a final decision.

Getting a rough net pay figure for budgeting.

Enter your hourly rate and hours.
Add your estimated overtime hours if applicable.
Enter your estimated federal tax rate in the tax field (a rough guide: 12% for income $11K–$44K, 22% for $44K–$95K, 24% for $95K–$201K for single filers in 2024).
The calculator shows an estimated take-home after federal tax.
Add your state tax rate separately for a more complete picture.

Finding your gross pay for a week that includes overtime hours.

Seeing the real-dollar impact of a percentage or flat raise.

Understanding what a monthly retainer means on a per-hour basis.

Estimate the number of hours per month the engagement requires.
Divide the monthly fee by the number of hours: $3,500 ÷ 40 hours = $87.50/hr.
Enter that hourly rate in the Pay Calculator to see equivalent annual figures.
Compare to a salaried alternative to assess whether the consulting rate is competitive.

Budgeting accurately when you are paid every two weeks rather than twice a month.

Note your biweekly net pay.
Multiply by 26 (paychecks per year) to get annual net pay.
Divide by 12 to get an average monthly net pay.
Note that two months per year will have three paychecks — plan for these windfalls in your budget.

Checking how much of a raise actually reaches your bank account.

Enter your current hourly equivalent and note the annual gross.
Enter the new hourly equivalent and note the new annual gross.
Calculate the gross increase.
Apply your marginal tax rate to the increase (the raise is taxed at your highest bracket, not your average rate).
Example: a $5,000 raise with a 22% marginal rate adds $3,900 per year or about $150 per biweekly paycheck after federal tax.
