Debt Payoff Calculator
See exactly how long to pay off your debt and how much interest you’ll save. Compare the debt snowball (smallest balance first) vs. debt avalanche (highest interest first) vs. minimum payments — side by side with your real numbers. Add up to 6 debts and see how extra payments accelerate your payoff.
Credit Card Interest Calculator
Find out what your credit card balance is really costing you. Enter your balance, APR, and monthly payment to see your total interest cost, payoff timeline, and how much you save by paying more than the minimum. Most people don’t realize that minimum payments on a $5,000 balance cost over $7,000 in interest.
Emergency Fund Calculator
Calculate your ideal emergency fund based on your actual monthly expenses. Input your rent, utilities, groceries, transportation, and other essentials. The calculator shows three targets — a $1,000 starter fund, 3-month fund, and 6-month fund — plus exactly how many months it takes to reach each one.
50/30/20 Budget Calculator
Instantly see how to split your income between needs, wants, and savings. Enter your monthly take-home pay and get exact dollar amounts for the 50/30/20 rule — the simplest budgeting framework that actually works. See how your savings rate builds an emergency fund over time.
Mortgage Refinance Calculator
See if refinancing your mortgage actually saves you money — or costs you more. Compare your current mortgage terms against a new rate. The calculator shows your monthly savings, total lifetime savings, and the critical break-even point — how many months until closing costs are recouped. Includes a clear “Worth It” or “Not Worth It” verdict so you know before talking to a lender.
Student Loan Payoff Calculator
Compare repayment strategies and see how extra payments save thousands on student loans. Add up to 5 loans with different rates and balances. The calculator compares minimum payments only vs. extra payments using the avalanche method (targeting the highest-rate loan first) — showing total interest saved and years cut from your timeline.
Net Worth Calculator
Track your total financial picture — assets minus liabilities — in one clear snapshot. Enter your checking accounts, savings, investments, retirement, home value, and vehicles on the asset side. Then enter your mortgage, student loans, car loan, credit card debt, and other liabilities. The calculator shows your total net worth with a visual breakdown of your largest assets and debts.
Credit Score Simulator
See how different financial actions would impact your credit score — before you take them. Enter your current score and credit profile, then select from 8 common actions: pay off a card, lower utilization, open a new account, get a limit increase, miss a payment, become an authorized user, close a card, or pay off a collection. The simulator estimates the point impact based on FICO scoring principles with a color-coded gauge from Poor to Exceptional.
