Finance Calculator App

Your paycheck shows one number. Your bank account shows another. Federal tax, state tax, Social Security, Medicare — it all adds up fast and most people never see the full breakdown.

Finance Calculator shows exactly where every dollar goes. Salary to hourly conversion, take-home pay after all US taxes, bonus tax comparison, real impact of your raise, investment growth, retirement planning, net worth tracking, and loan comparison — 8 calculators in one app. No account required. No subscription. Works offline.

Salary Calculator
Convert between annual, monthly, weekly, daily, and hourly salary. Enter your income and adjust hours per week and weeks per year to match your schedule. Works for salaried, hourly, and part-time workers.

Paycheck Calculator — All 50 US States
Enter your annual salary, state, pay frequency, and filing status. See your exact take-home pay after federal income tax, state income tax, Social Security, and Medicare. Covers all 50 states with 2026 tax rates. Add 401k and health insurance as pre-tax deductions. Supports weekly, bi-weekly, semi-monthly, and monthly schedules.

Bonus Tax Calculator
Most bonus calculators only show a gross amount based on percentage. This one shows actual take-home after all deductions. Enter your bonus, annual salary, filing status, and state. Results show the flat 22 percent withholding method versus the aggregate method side by side — federal tax, state tax, Social Security, and Medicare under each, with your real take-home for both.

Raise Calculator
Enter your current salary, raise as a percentage or fixed amount, and state. See your new annual salary, extra take-home per paycheck after all taxes, and effective tax rate on the raise. Supports all pay frequencies.

Investment Calculator
Enter initial investment, monthly contribution, return rate, and time horizon. See projected value at your own rate plus automatic conservative and aggressive scenario comparisons. Includes a year-by-year growth chart showing compound interest over time.

Retirement Calculator
Enter your age, retirement age, current savings, monthly contribution, expected return, and target monthly income. Uses the 4 percent withdrawal rule to compare required nest egg versus projected savings. Shows whether you are on track and the gap amount if you are behind.

Net Worth Calculator
Unlike basic tools that only show one number, this one compares your result to a real benchmark. Add assets — cash and savings, investments, retirement accounts including 401k and IRA, home value, vehicles. Add liabilities — mortgage, auto loans, student loans, credit card debt. Net worth calculated instantly, then compared to the US median for your age group using Federal Reserve data.

Loan Comparison
Enter amount, rate, and term for two loan offers. See monthly payment, total interest, and total cost side by side. Shows which loan costs less over the full repayment period.
