Loan Payment Calculator with Extra Payments
Whether it is a car loan, a personal loan or any fixed rate instalment loan, this loan payment calculator with extra payments does the sums lenders do not always volunteer: type in the amount, the annual rate and the term, and you get the fixed monthly payment plus the two numbers that really matter, monthly loan interest and total repaid over the life of the loan. Think of it as a personal loan interest calculator with extra payments built in, showing exactly how much interest each extra payment wipes out. It works in any currency, because it only crunches the numbers you type.

Your result
Assumes a fixed rate and equal monthly payments. Fees, insurance and any balloon payment are not included.
The formula
Monthly payment = P × r × (1 + r)^n ÷ [(1 + r)^n − 1], where P is the loan amount, r is the monthly interest rate and n is the number of monthly paymentsTotal repaid = monthly payment × n, and total interest = total repaid − P
A worked example
A $20,000.00 loan at 7% APR over 5 years (60 months) comes to a monthly payment of $396.02, total repayments of $23,761.20 and total interest of $3,761.20.
More about the Loan Calculator
Compare loans by total cost, not just the monthly payment
Lenders advertise the monthly payment and bury the total cost, so run every offer through the calculator above and read the total interest line, because that is the true price of borrowing. A longer term always lowers the payment and always raises the total: on a $20,000 loan at 7%, stretching from 3 years to 5 drops the payment from about $618 to $396 a month but adds roughly $1,500 in interest. Decide whether the breathing room is worth the price before you sign, and compare offers using APR rather than the headline rate. APR folds most fees in, so it is the more honest number.
Small habits that shrink the interest bill
If your loan allows extra payments without a penalty, even modest ones change the maths: interest is charged on the outstanding balance each month, so every extra dollar of principal you clear early stops earning interest for the lender from that month onward. Rounding a $396 payment up to $450, or making one extra payment a year, shaves months off the term and hundreds off the total, the effect is biggest in the early years, when the balance is highest. If rates have fallen or your credit has improved, refinance the same way: compare total interest on the old and new loan, not just the new payment.
Why your EMI is fixed (and what moves it)
Work it through once with real numbers. A $500,000 loan at 9% annual interest over 5 years (60 months): the EMI comes to $10,379.18 a month, total payments of $622,750.66, total interest $122,750.66. Now stretch the same loan to 20 years: the EMI drops to about $4,498.70, less than half, but total interest balloons to roughly $579,690. Same borrowing, nearly five times the interest. That single comparison is the most valuable thing this page can teach you.
Most people use an EMI calculator at three moments: before signing (sanity checking the lender's quote), when choosing between terms (the comparison above), and when considering a prepayment or refinance (re run with the new numbers). A fourth use is quieter but important: checking affordability honestly. Lenders approve EMIs up to 40 to 50% of income; that does not mean you should take it. Leave margin for the months when life happens.
Prepayments and reading your amortization
Three tips from people who have been burned. First, always look at total interest before falling in love with a low EMI, the monthly figure is marketing, the total is the price. Second, ask about every fee the EMI quote excludes: processing fees, insurance bundled into the loan, prepayment penalties. Third, if your income is irregular, model the EMI against your worst quarter, not your best month. A loan is a promise you make to your future self on a bad day.
What this calculator does not do: it assumes a fixed rate, equal monthly payments, no fees, no taxes and no missed payments. Real loans have all of those. Treat the result as the clean mathematical core of your loan, accurate to the formula, and layer your lender's fees and terms on top when you compare real offers. The formula is the standard amortisation one every bank uses, so the EMI itself will match any honest quote.
One loan at three tenures, compared honestly
Suppose you borrow 300,000 at a fixed 7 percent. Over 20 years the calculator returns an EMI of 2,325.90 a month, and paying it 240 times totals about 558,215, meaning roughly 258,215 of that is interest. Shorten the term to 15 years and the EMI rises to 2,696.48, but the total falls to about 485,367, so interest drops to roughly 185,367. The shorter loan costs 370.58 more each month and saves about 72,848 overall.
Stretch the same loan to 30 years and the pattern reverses hard: the EMI falls only to 1,995.91, a saving of about 330 a month against the 20 year figure, while total interest balloons to roughly 418,527. That asymmetry is the real lesson of the calculator. Extending a tenure buys a surprisingly small monthly relief at a very large lifetime price, because in the early years the extra payments are almost entirely interest on a balance that barely moves.
Comparing two offers that hide different costs
Lenders compete on the EMI figure because it is the number buyers remember, so two quotes with identical EMIs can still be different loans. Line them up on the four inputs the calculator actually uses, amount, rate, tenure and any fee added to the loan, and then compare the total paid, not the monthly figure. An offer with a slightly lower rate but a processing fee folded into the principal can quietly cost more than the plainer offer beside it.
Watch especially for the quote built on a longer tenure than you asked for, and for teaser structures where the EMI steps up later. Run each offer at the same tenure first, so the rate difference stands alone, then run your preferred tenure for the winner. If a salesperson resists giving you the rate and tenure in writing, that resistance is itself information: the calculator can only protect you when the inputs are the real ones.

EMI questions
Why is my first year of EMIs almost entirely interest?
It comes down to amortisation, the way each EMI is split. Every payment covers the interest on your remaining balance first, with whatever is left chipping away at the principal. Early on, the balance is at its biggest, so interest swallows most of each payment and the principal barely moves for years. That is how the math works, not a trick, but it is exactly why an extra payment in year two saves far more than one in year twenty.
How do I actually compare a 20 year loan against a 25 year one?
Look past the monthly figure and compare the total interest instead. That is where the real price hides. Run both terms through the calculator and check the total interest line; the longer term's smaller EMI almost always costs dramatically more over the life of the loan. Pick the shortest term whose payment you can make comfortably every month, with room to spare for the rough months.
Does this handle floating or variable interest rates?
Not really, the calculator assumes your rate stays fixed for the whole term. On a floating rate loan the lender recalculates when rates move, either changing your EMI or stretching the tenure. Use it with your current rate to see where you stand today, then run it again whenever the rate changes.
Why does my bank's EMI differ slightly from this calculator?
Usually it is one of three things: fees and charges the bank folds into the loan, small differences in how the monthly rate is rounded, or the disbursal date, interest starts accruing from day one, not from your first EMI. A gap of a few units of currency is normal; a big gap means fees are hiding somewhere, so ask.
What happens if I prepay part of the loan midway?
A prepayment lands straight on the principal, which shrinks every interest charge that follows. That is why even one extra payment a year can knock years off a loan. This calculator models the fixed schedule, so to see the effect, run it again with the reduced balance and the remaining term after you prepay.
What is the difference between a flat interest rate and a reducing balance loan?
A flat rate charges interest on the original loan amount for the whole term, so you keep paying interest on money you have already repaid. It costs far more than it sounds. A reducing balance loan charges interest only on what you still owe, so every payment lowers the interest on the next one. This calculator uses the reducing balance method, which is the standard arithmetic behind real bank loans.
Does a bigger down payment really lower my EMI?
Yes. Your EMI is calculated on the amount you actually borrow, so every unit you pay upfront shrinks both the monthly payment and the total interest you will owe. A bigger down payment can also help you qualify for a shorter, cheaper term. Try it above: enter the loan amount after subtracting your down payment and watch both numbers fall.
Is a longer or shorter EMI tenure better?
Shorter tenures save significant total interest but raise monthly payments. Longer tenures lower payments but can add years of extra interest cost. Choose the shortest tenure whose monthly payment still leaves room for savings and emergencies.
How is EMI calculated?
EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the principal, r is the monthly interest rate, and n is the number of months. For a ₹10,00,000 loan at 9% annual for 5 years (r = 0.0075, n = 60), the EMI is about ₹20,758. Reducing the rate or tenure changes the EMI, compare both before signing.
Frequently asked questions
What is APR and how is it different from the interest rate?
APR (annual percentage rate) is meant to include most lender fees alongside the interest rate, so it is usually the more honest number to compare between offers. If your loan offer states a separate interest rate and APR, use the APR here for the more realistic payment.
Does this work as an EMI calculator?
Yes, EMI (equated monthly instalment) is the same fixed payment concept under a different name, common in Indian and Gulf lending. Enter the principal, annual rate and term in months or years and the result is your EMI.
Does paying extra each month save money?
Yes. Every extra dollar, pound or euro you pay above the scheduled payment comes off the principal directly, which shortens the loan and cuts the total interest, since interest is charged on the remaining balance. This calculator shows the standard schedule; check with your lender that extra payments are accepted without a penalty.
What is a loan amortization schedule?
An amortization schedule is a table of every loan payment, split between interest and principal. Early payments are mostly interest; later payments clear principal faster. This loan calculator gives the fixed monthly payment that such a schedule is built on.
What fees should I watch for on a personal loan?
In the US, origination fees of 1 to 8% are often deducted from the amount you actually receive, a $10,000 loan with a 5% fee puts only $9,500 in your pocket. In the UK, check for early repayment charges (lenders can charge up to 58 days' interest), and everywhere, watch for late payment and PPI style add ons.
How much can I borrow with a $500 a month payment?
It depends on the rate and the term, which is why a payment first question needs the calculator above: a longer term borrows more money for the same monthly payment but piles on total interest. Enter $500 as your target and adjust the term and rate to see the loan size each combination supports. Shorter terms shrink what you can borrow, and the interest bill.
Why does my loan balance barely move in the first year?
Because most of your early payments go to interest, not the balance. On a fixed payment loan, interest is charged on the full outstanding balance each month, so when the balance is highest, interest eats the largest share. As the balance falls, more of each payment attacks principal and the balance starts dropping faster. The amortization view in the calculator above shows this front loaded pattern month by month.
How do I calculate loan interest payments?
Use the amortization formula M = P × r(1+r)^n ÷ ((1+r)^n − 1) with your principal, monthly rate, and term to get the payment; total interest equals (payment × n) − principal. Early payments are mostly interest, with principal growing each month. Making extra principal payments shortens the term and cuts total interest.
How much will my monthly loan payment be?
It depends on the loan amount, interest rate, and term, a ten thousand dollar loan at eight percent for five years costs about two hundred two dollars a month. Our loan calculator gives you the exact payment instantly.
How much interest will I pay on a personal loan?
It depends on the amount, rate, and term, for example, a $10,000 loan at 10% APR over 3 years costs about $1,616 in total interest. Shortening the term or lowering the rate cuts the total interest sharply.
