How to use these money calculators
1. Know your real payment
Use the Loan Calculator before you borrow. The amortization table shows how much of each year goes to interest — and the extra-payment field shows how a small monthly bump can cut years off the loan.
2. Attack debt with a plan
The Debt Payoff Calculator compares snowball and avalanche with your actual balances, so you can pick a strategy knowing exactly what it costs in dollars and months.
3. Give savings a deadline
A goal without a date is a wish. The Savings Goal Planner turns "someday" into a month and year — and tells you the exact deposit needed to hit a deadline.
4. Let compounding do the heavy lifting
Run the Compound Interest Calculator with 10, 20, and 30 years and watch the growth bar take over the chart. Time in the market is the variable that changes everything.
Frequently asked questions
How is a monthly loan payment calculated?
Monthly payments use the standard amortization formula: M = P × r ÷ (1 − (1 + r)−n), where P is the amount borrowed, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. Early payments are mostly interest; later payments are mostly principal — the amortization table on this page shows that shift year by year.
What is the difference between APR and APY?
APR (annual percentage rate) is the yearly rate before compounding is taken into account and is what lenders quote on loans. APY (annual percentage yield) includes the effect of compounding and is what banks quote on savings. At the same stated rate, APY is always slightly higher than APR because interest earns interest.
Debt snowball vs debt avalanche — which is better?
The avalanche method (pay extra toward the highest interest rate first) is mathematically cheapest — it always minimizes total interest. The snowball method (pay extra toward the smallest balance first) often wins psychologically, because early wins keep people going. The debt payoff calculator on this page runs both side by side so you can see exactly what the difference costs in dollars and months.
Does compounding frequency really matter?
It matters, but less than most people expect. Moving from annual to monthly compounding adds a modest boost; moving from monthly to daily adds very little. The factors that dominate long-term growth are your contribution amount, your rate of return, and — above everything else — how many years you stay invested.
Are these calculators free and private?
Yes. Every calculator is completely free with no signup and no limits, and all math runs locally in your browser. Loan amounts, balances, and goals are never uploaded to a server. The only thing saved on your device is your light/dark theme preference.
Is this financial advice?
No. These calculators are educational tools that show you the math behind loans, savings, and debt payoff. Results are estimates based on the numbers you enter and do not account for fees, taxes, or rate changes. For decisions about your specific situation, consult a licensed financial professional.
