40 free calculators

Smart financial decisions start with accurate numbers. Our collection of 40 free finance calculators covers every milestone of your financial life — from paying off your first credit card to planning a comfortable retirement. No spreadsheets required, no sign-up, and no paywalls.

Borrowing and Debt

Whether you're shopping for a home, a car, or a personal loan, our Mortgage Calculator and Loan Calculator instantly show your monthly payment, total interest cost, and full amortization schedule. The Amortization Calculator lets you model extra payments to see exactly how much interest you'll save by paying down principal faster. Already carrying high-interest debt? The Credit Card Payoff Calculator shows your payoff date and total interest cost under different monthly payment scenarios.

Saving and Investing

The most powerful force in personal finance is compound interest. The Compound Interest Calculator visualises how your savings grow over time with regular contributions — a compelling argument for starting early. The Investment Calculator and Retirement Calculator let you model different return rates and savings rates to build a realistic long-term plan. For US savers, the 401(k) Calculator factors in employer matching to show your true contribution rate.

Income and Tax

Understanding your take-home pay is the first step to budgeting. The Paycheck Calculator estimates your net pay after federal and state taxes, Social Security, and Medicare. The Salary Calculator converts between hourly, weekly, monthly, and annual compensation so you can compare job offers on an equal footing. For quick purchasing decisions, the Discount Calculator and Sales Tax Calculator give you the real price in seconds.

For business owners, the Profit Margin Calculator, Markup Calculator, and Break-Even Calculator are essential tools for pricing strategy and financial planning.
