Calculators for common borrowing decisions
LoanMathWorks organizes its tools into four main categories so you can quickly find the calculator that fits the question you're trying to answer.
Mortgage Calculators
Estimate payments, affordability, amortization, payoff timing, refinancing costs and more.
Auto Loan Calculators
Compare financing costs, payment options, affordability and early payoff scenarios.
Personal Loan Calculators
Estimate loan payments, compare payoff strategies and understand debt-to-income ratios.
Debt & Interest Calculators
Explore APR, simple interest, compound interest and side-by-side borrowing comparisons.
Make the numbers easier to understand.
Loans can involve interest rates, payment schedules, fees, amortization and other numbers that are difficult to evaluate at a glance.
LoanMathWorks is designed to help break those numbers down into understandable estimates so you can explore different scenarios before making a financial decision.
The goal is not to tell you what decision to make. It is to give you useful tools that help you better understand the numbers behind that decision.
Start with your numbers
Enter the loan amount, rate, term, payment or other assumptions relevant to the calculator.
See the estimated result
Review payments, interest, payoff timing and other useful estimates based on your inputs.
Compare different scenarios
Adjust rates, terms, payments or other variables to see how changing the assumptions affects the result.
Educational tools, not financial products.
LoanMathWorks is an independent informational website. Our calculators are designed to provide estimates and educational context, not personalized financial recommendations or lending decisions.
How our calculators work
We believe financial calculators are more useful when you can understand the assumptions behind them. Our methodology page explains the formulas, rounding practices and common assumptions used throughout LoanMathWorks.
