Loan Calculators
A loan calculator shows the payment, total interest and true cost of a loan - car, personal, student, gold or a plain amortized loan - before you sign.
A loan calculator is a free tool that shows the monthly payment, total interest and total cost of a loan before you sign. Every loan shares one structure. You borrow a principal, repay it over a set term, and the interest rate sets the extra you pay. The details change by loan type. A car loan adds sales tax and a trade-in. A gold loan depends on purity and a loan-to-value limit. A student loan adds payoff strategies, a tax deduction and forgiveness rules.
This hub gathers every loan calculator in one place. Pick the tool that matches your loan. The loan payment calculator gives you the monthly figure, while the true-cost and payoff tools show what a loan costs over its full life. For a home loan, use the mortgage and property calculators.

What Are the Main Types of Loans?
Loans split into four types on this page: general and personal, auto, gold, and student. Each type sets its own inputs and rules.
General and Personal Loans
Fixed-rate, unsecured loans repaid in equal monthly installments. Borrowers use them for consolidation, big purchases and emergencies.
Auto Loans
Secured by the vehicle. The financed amount depends on price, sales tax, trade-in and down payment.
Gold Loans
Secured against gold jewelry or coins. The loan depends on weight, karat purity, the gold rate and a loan-to-value limit.
Student Loans
Long-term education loans with three extras: payoff strategies, an interest tax deduction, and forgiveness programs such as PSLF.
How Are Loan Payments Calculated?
A loan payment is calculated from three inputs: the principal, the monthly interest rate and the number of payments. Change any one input and the payment changes.
Nearly all loans on this page are amortized, so you pay the same fixed amount each month while the split between interest and principal shifts over the term. Early payments are mostly interest and later payments are mostly principal. A longer term lowers the monthly payment but raises the total interest, and these tools let you test that trade-off.
What Do the Key Loan Terms Mean?
Seven terms decide what a loan costs. Each definition below states the term in one line.
- Principal
- Principal is the amount you borrow before any interest is added.
- Interest Rate vs APR
- The interest rate is the cost of borrowing the principal. The APR adds the fees, so it is the true yearly cost. Compare loans by APR.
- Term
- The term is how long you take to repay. A longer term lowers the monthly payment but raises the total interest.
- Amortization
- Amortization is the schedule that splits each fixed payment between interest and principal, with interest front-loaded.
- Secured vs Unsecured
- A secured loan is backed by collateral such as a car or gold, while an unsecured loan has none and so carries a higher rate.
- Down Payment
- A down payment is money paid up front. It reduces the amount you finance, and car loans use it most.
- Origination Fee
- An origination fee is a one-off charge to set up the loan, which a lender often adds to the balance.
Frequently Asked Questions
What Is the Difference Between the Loan Calculator and the Loan Payment Calculator?
The Loan Payment Calculator shows one number: the fixed monthly payment. The Loan Calculator shows that payment plus the total interest and the total repaid. Use the Loan Calculator to compare the full cost of two loans.
Which Calculator Should I Use for a Car Loan?
Use the Auto Loan and Car Payment Calculator. It adds sales tax, a trade-in value and a down payment, and those three inputs change the amount you finance.
How Much Can I Borrow?
Lenders size a loan mainly from your income, existing debts and credit score, usually keeping your total debt payments under about 36 to 43 percent of gross income. Enter a payment you can afford into the loan calculator to work back to a realistic amount.
How Are the Student Loan Tools Different From a Personal Loan Calculator?
Student loans have three features other loans lack: multiple balances paid by strategy, an interest tax deduction, and forgiveness programs such as PSLF. The student and teacher tools model those, while the personal loan calculator gives a straight payment and cost estimate.
Do These Calculators Include Fees and Insurance?
The core tools use the amount, rate and term. Origination fees and insurance vary by lender, so add them to the loan amount or check the specific tool for a fee input.
Is a Lower Monthly Payment Always Cheaper?
No. A lower payment usually comes from a longer term, which spreads the interest over more months and raises the total cost. Compare the total interest before you choose a term.
Is Anything I Enter Stored?
No. Every calculator runs in your browser, and nothing you type leaves your device unless you save a result, which stays on your device.
