What does a loan calculator do?

A loan calculator estimates monthly payments, total interest, and the full amortization schedule based on principal, interest rate, and term. It helps you compare loan options and plan your budget.

What is PITI?

PITI stands for Principal, Interest, Taxes, and Insurance. For mortgages, it is the full monthly housing cost. The mortgage tab includes optional property tax and insurance for a realistic estimate.

What is an amortization schedule?

The amortization schedule shows how each payment is split between principal and interest over time. Early payments are mostly interest; later payments are mostly principal. Use it to see payoff progress.

What interest rate should I use?

Rates vary by lender, credit score, and market. Use this calculator to compare scenarios (e.g. 15 vs 30 years) and see how rate changes affect your payment and total cost.

Is my data private?

Yes. All calculations run in your browser. Your numbers are never sent to a server, so your financial data stays private.

Does it support both mortgage and personal loans?

Yes. The calculator supports mortgage mode (with optional taxes and insurance) and personal loan mode. Switch tabs to choose. Results include monthly payment, total interest, total cost, and full amortization table.

How do I calculate a mortgage?

Enter home price and down payment (as amount or percentage). The loan amount is calculated automatically. Then add interest rate, term, and optionally annual property tax and insurance for PITI.

What if I make extra payments?

Extra payments reduce principal faster and shorten the loan term, saving interest. This calculator shows the standard schedule; for extra-payment scenarios, run a new calculation with a lower principal or shorter term.

Are the results accurate?

Results are estimates. Actual offers depend on your credit, lender, and fees (e.g. closing costs, PMI). Use this tool to compare options and budget; get exact numbers from your lender.

Can I use this for car or other loans?

Yes. Use the personal loan tab for auto loans, student loans, or any fixed-term loan with a fixed interest rate. Enter the loan amount, rate, and term to see payments and amortization.
