Personal Loan Calculator

Every monthly payment is determined by a standard amortization formula that factors in three variables: the loan principal, the annual interest rate (converted to a monthly rate), and the total number of payments. The formula produces a fixed payment where each installment covers that month's accrued interest first, then reduces the principal. Because you owe more early in the loan, a larger share of each early payment goes toward interest; that share shrinks over time as the balance decreases. This is why paying a little extra each month — and asking that it be applied to the principal — can meaningfully reduce the total interest you pay.

A good personal loan rate in 2026 is typically below 12% APR. Borrowers with excellent credit (FICO 740+) often qualify for rates between 6% and 12% through banks and credit unions. Those with good credit (670–739) can expect rates from 13% to 20%, while fair-credit borrowers (580–669) may see offers of 20–30% or higher. Federal Reserve rate movements also influence lender benchmarks, so prevailing rates can shift year to year. The best way to know your rate is to get pre-qualified with multiple lenders — it uses a soft credit pull that won't affect your score.

The right choice depends on how much you need, how fast you can repay, and what rates you qualify for. Personal loans give you a fixed rate, fixed monthly payment, and a defined payoff date — advantages for large expenses spread over 2–7 years. Credit cards offer flexibility and can be interest-free if you pay the full balance each month, making them better for smaller, short-term expenses. However, credit card APRs average over 20% and compound quickly if you carry a balance. If you're consolidating existing card debt, a personal loan at a lower fixed rate almost always wins on total cost.

Stretching a loan over a longer term lowers your monthly payment but significantly increases the total interest you pay. Consider a $15,000 loan at 10% APR: over 3 years the monthly payment is about $484 and total interest is roughly $2,400; stretch the same loan to 6 years and the payment drops to $278, but total interest climbs to approximately $5,000 — more than double. Shorter terms keep total costs down but require a higher monthly commitment. Use this calculator to find the term that balances an affordable payment with a reasonable total interest cost.

Getting the best rate starts with your credit score — the single biggest factor lenders weigh. If time allows, spending a few months paying down revolving balances to lower your credit utilization and correcting any errors on your credit report can meaningfully improve your offer. Beyond credit, compare quotes from at least three sources: your primary bank, a credit union, and one or two online lenders. Pre-qualification typically uses a soft pull and won't hurt your score. Also consider a secured loan, co-signer, or autopay discount if available. Even a 1% rate improvement on a $20,000 loan saves roughly $500–$1,000 over a 5-year term.
