Free Financial Calculators
Run the numbers on your own debt, savings and retirement questions. Every calculator is free and works without an account.
Pay Down Debt
How long will it take to pay off my credit card, and how much interest will I pay?
Enter your balance, APR and minimum payment to see your payoff date and total interest, then see how paying more shortens it.
Should I pay off my smallest debt or my highest-rate debt first?
Run both payoff methods on your real balances and rates, and see the total interest and payoff date for each.
Will a 0% balance transfer actually save me money after the fee?
See how much a balance transfer saves, transfer fee included, and what happens if a balance is left when the promo ends.
What will my student loan payment be, and when will it be paid off?
Compare the Standard 10-year plan with Income-Based Repayment, and see what a small extra payment does to your timeline and interest.
Save and Plan
How much do I need to save each month to reach my goal on time?
Enter a goal and a date to get the monthly amount, then see how saving more moves the date up.
How much am I leaving on the table by not getting my full 401(k) match?
Project your balance at retirement with your current contribution and with the full employer match.
One question at a time, or your whole picture
These calculators answer one question with the numbers you type in. aiSmartBudget runs the same kind of math on your real accounts and bills, and shows you the days ahead when your balance runs thin.
