About this loan calculator
This is a general-purpose amortizing loan calculator — it works for personal loans, debt consolidation loans, student loans, or any other fixed-rate installment loan where you borrow a lump sum and repay it in equal monthly payments over a set term. Rather than modeling one specific loan type's quirks, it uses the same core amortization math that underlies almost every fixed-rate consumer loan: a level monthly payment sized so the balance reaches exactly zero on the final payment.
The calculation converts your annual interest rate to a monthly rate, then solves for the payment amount using your loan amount and total number of monthly payments (your term in years times 12). Every payment you make is the same size, but the mix inside it changes over time — early payments are weighted toward interest, and later payments are weighted toward principal, because interest is charged on whatever balance remains.
Term length has an outsized effect on total cost. Stretching a loan from 3 years to 7 years lowers the monthly payment, which can make it easier to qualify or fit a budget, but it also means paying interest for more months — so the total interest paid over the life of the loan is usually significantly higher on a longer term, even at the same interest rate. Shorter terms cost more per month but less overall.
Interest rates on personal loans vary enormously based on credit score, income, existing debt, and the lender — from single digits for borrowers with excellent credit to well over 30% APR for subprime borrowers, especially with online or short-term lenders. Because of that spread, the rate you're quoted matters just as much as the loan amount itself when estimating your real monthly payment.
This tool is an estimate for informational purposes only. It calculates principal and interest based on the numbers you enter, but real loans can include origination fees, prepayment penalties, variable rates, or other charges that aren't reflected here. Actual approval, rate, and terms depend on your lender and credit profile — use this calculator to compare scenarios and budget, then confirm exact figures with your lender's official loan estimate.
Loan calculator questions
How loan payments and amortization work.
How is a loan payment calculated?
This calculator uses the standard amortization formula: it spreads your loan amount across equal monthly payments over your chosen term, using your annual interest rate converted to a monthly rate, so the balance reaches zero on the final payment.
What loan types can I use this calculator for?
Any fixed-rate installment loan repaid in equal monthly payments — personal loans, debt consolidation loans, student loans, or similar. It is not designed for revolving credit like credit cards, which don't amortize the same way.
Why does a longer loan term lower my payment but cost more overall?
A longer term spreads the same loan amount across more monthly payments, which lowers each payment. But because interest keeps accruing on the remaining balance for more months, the total interest paid over the full term is usually higher than with a shorter term at the same rate.
What interest rate should I use if I don't know mine yet?
Personal loan rates commonly range from around 6% for borrowers with excellent credit to 30%+ for subprime borrowers. Try a few realistic rates in the calculator to see how much your estimated payment could vary before you apply.
Does this calculator include fees?
No. It calculates principal and interest only. Many lenders also charge an origination fee (often 1-8% of the loan amount) deducted from your loan proceeds, which isn't reflected in this payment estimate.
What happens if I enter a 0% interest rate?
The calculator simply divides the loan amount evenly across the number of monthly payments, since the standard amortization formula can't divide by a zero rate. This is useful for modeling interest-free loans from family or promotional financing.
Can I pay off the loan faster than the term I enter?
This calculator shows the standard payment schedule for the full term you enter. Making extra payments toward principal will shorten the actual payoff time and reduce total interest, but check your loan agreement first — some loans include prepayment penalties.
