Loan Calculator

A financing quote becomes easier to judge when the monthly payment and the lifetime cost are visible together. Enter the principal, rate and term to estimate the fixed installment, total repayment and remaining balance after every payment. The result is a planning estimate, not a lender approval or a binding disclosure.

USD, EUR, GBP and TRY change the number format and currency symbol. This English version does not add country-specific taxes, insurance or origination charges. If those costs are financed, add them to the principal; if they are paid upfront, compare them beside the result.

Use the rate shown for the payment schedule

Select Monthly when the agreement states a monthly interest rate. Select Yearly for a nominal annual rate; the calculator divides that figure by 12. A nominal 6% yearly rate therefore becomes 0.5% per month. This is not a compound-interest conversion, so a compound interest calculator may show a different monthly equivalent.

The note matters because an interest rate and APR do not describe exactly the same thing. The rate drives the principal-and-interest payment. APR may include certain lender fees and other required credit costs, depending on the disclosure rules in the market. A loan APR calculator needs those fees and their timing; this page only uses the rate you enter.

The Calculate Interest tab works in reverse from total repayment, term and a known rate to estimate the principal those payments support. It does not solve for an unknown rate. In other words, it is a loan amount estimator, not a loan interest rate calculator.

What is included in the monthly payment?

For a fixed-rate installment loan, the equal-payment formula is shown below. P is principal, r is the monthly rate, n is the number of payments and M is the monthly payment. A regular loan EMI calculator uses the same annuity relationship.

M = P × r(1+r)ⁿ ÷ ((1+r)ⁿ − 1)

Each payment contains interest on the opening balance and a principal reduction. The amount stays level, but the split changes: early payments contain more interest, while later payments close more principal. At a zero rate, principal is simply divided by the number of months.

An interest-free loan can be tested by entering 0%. The payment then equals principal divided by term. “Zero interest” does not always mean zero borrowing cost: a setup fee, mandatory purchase or lost cash discount can still increase the effective price.

Term and total cost answer different questions

With no added fees, a 100,000 loan at 3% per month for 12 months produces a payment of 10,046.21 and a total repayment of 120,554.50. Extending the term usually lowers the monthly loan payment, but interest applies for more months. Shortening it does the opposite. Compare the payment and total cost at the same time rather than choosing the smallest installment.

The loan amortization schedule lists principal, interest and remaining loan balance for every month. It doubles as a loan payment schedule calculator when you need the due sequence, and it gives the balance needed for a payoff request on a chosen date. A lender's actual loan payoff figure can also include daily interest, a permitted fee or a timing adjustment, so the table is not a settlement statement.

Affordability is personal. A loan affordability calculator would also need income, existing obligations, living costs and a safety margin; this page does not infer those values. Test a payment against the amount that remains after essential expenses, not only against gross income or a lender's maximum offer.

A mortgage payment is not the whole housing budget

A mortgage calculator or home loan calculator on this page covers principal and interest. In many markets, the payment collected by a servicer may also include property taxes and insurance through escrow. A down payment reduces the amount borrowed, while appraisal, title, legal and closing costs may require separate cash. Use the Loan Estimate or equivalent local disclosure to reconcile those items before signing.

A house loan calculator also assumes that the entered rate remains unchanged. For an adjustable-rate mortgage, the schedule is only a scenario based on today's rate. Run additional cases at higher rates to see whether the future payment still fits the budget.

The same formula supports different borrowing decisions

For a personal loan calculator or consumer loan calculator, enter the cash you will actually receive if fees are withheld upfront, then compare it with the amount you must repay. This makes a bank loan calculator useful without pretending that every lender has the same charge structure.

For a car loan calculator, subtract the down payment and trade-in allowance from the agreed vehicle price, then add only the costs being financed. The same setup works as a vehicle loan calculator or auto loan calculator for new and used cars. Dealer extras that are not part of principal should stay outside the field.

A business loan calculator is most useful when its payment dates are placed next to expected cash receipts. Seasonal revenue may make a level monthly installment unsuitable even when the annual profit looks sufficient. If the lender uses a balloon payment, interest-only period or changing installments, model those terms separately because this tool assumes equal payments.

How the deferral scenario is built

For an initial grace period, the calculator adds accrued interest to the balance during months with no payment and keeps the original total term. Fewer paying months remain, so the later installment rises. A mid-term deferral follows the same principle: interest continues during skipped months and the payment is recalculated from the remaining balance.

On the 100,000 example at 3% per month over 12 months, a three-month initial deferral raises the balance to 109,272.70. The first of the remaining nine payments becomes 14,034.31, and total repayment rises from 120,554.50 to 126,308.83. If the lender extends the maturity instead of keeping it fixed, or charges a separate deferral fee, its schedule will differ.

Use the displayed rows to see when interest was capitalized. This is more informative than treating a skipped installment as free time: the cash-flow relief occurs now, while the extra cost is carried into later payments.

Compare offers on the same basis

• Use the same principal, payment frequency and loan term for every lender. Compare interest rate, APR, upfront cash and total repayment in separate columns.
• Check whether the quote is a fixed-rate loan for the full term. A promotional period followed by a variable rate cannot be represented by one constant input.
• Ask how extra principal payments are applied and whether a prepayment charge exists. The loan repayment schedule here assumes only the stated monthly installment.
• Confirm which fees are financed and which are paid at closing. Currency selection changes display only; it does not supply exchange-rate risk or local lending rules.

A good loan cost calculation explains where the number came from. Keep the lender's written disclosure beside the result, match the rate type, and account for costs the formula does not know. That produces a more useful decision than relying on the advertised payment alone.
