Calculators for United States

Mortgage, 401(k), Roth IRA, federal tax, and retirement in $ (USD). Free tools for mortgages, tax, retirement, loans, and budgeting—then track spending in Atlantic on iPhone and iPad.

US planning often mixes gross pay, pre-tax retirement contributions, mortgage PITI, student loans, and state-level quirks. These calculators use USD and common US assumptions—401(k) or Roth IRA growth, federal tax brackets, mortgage payment breakdowns, and loan amortization—so you can sanity-check a decision before talking to a lender or CPA.

Pick a tool by goal: housing payment, retirement projection, take-home pay, or debt payoff. Rates and limits change; always confirm with official IRS guidance, your HR benefits booklet, or your loan estimate. Results are educational only.

Atlantic Finance helps you track day-to-day spending and budgets on iPhone and iPad when you are ready to move from a one-time calculation to a weekly money habit.
