Personal Loan Calculator
Monthly payment, total interest, origination fees, and the cash you'll actually receive — so you can compare lenders on true cost, not just the advertised rate.
- Loan amount$15,000.00
- Origination fee (0.00%)−$0.00
- Cash deposited to you$15,000.00
- Total of 36 payments$17,935.73
- Total cost (payments + fee)$17,935.73
The origination fee is the fine print that changes the deal: a “low” rate with a 6% fee can cost more than a slightly higher rate with no fee. Always compare the total cost and check your bank or credit union — they often beat online lenders on both rate and fees.
How the math works
A personal loan is a fixed-rate installment loan: you receive a lump sum up front and repay it in equal monthly payments over a set term, typically one to seven years. Each payment is split between interest and principal by the amortization formula: monthly payment = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the loan amount, r is the monthly rate (APR ÷ 12), and n is the number of months. Early payments are mostly interest; later payments are mostly principal.
Two costs matter beyond the APR. The origination fee — typically 1–8% — is deducted from the cash you receive, yet you repay the full loan amount plus interest. A $15,000 loan with a 5% fee deposits only $14,250 into your account, so the effective cost is higher than the stated APR suggests. Late fees and optional add-ons like credit insurance can push the cost higher still.
The figure to compare across lenders is total cost: (monthly payment × number of payments) − cash actually received. Two loans with the same APR can have very different total costs once fees differ — which is why this calculator shows the cash you will actually receive alongside the payment. A slightly higher APR with no fee often beats a lower APR with a steep fee.
Worked example
Borrow $15,000 at 14.9% APR for 36 months with a 5% origination fee. The monthly payment is $519.25 and total interest is $3,693 — but only $14,250 lands in your account, since the lender keeps $750 as the fee. Your true cost above the cash received is $4,443. Now consider a competing offer at 16.9% with no fee: the payment is $534.04, total interest is $4,226, and you receive the full $15,000 — making it $217 cheaper overall despite the higher rate. The advertised rate never tells the whole story.
What to watch for
- Compare total cost, never APR alone. An origination fee can make a lower-rate loan more expensive than a higher-rate loan with no fee — add the fee to total interest before choosing.
- Check banks and credit unions, not just online lenders. Credit unions in particular often offer lower rates and smaller fees to members, and membership is usually easy to obtain.
- Borrow only what you need. Because the payment is fixed, borrowing an extra $2,000 "just in case" raises every monthly payment and the total interest — keep a small cash buffer in savings instead.
- Confirm there is no prepayment penalty, in writing, before you sign. Most personal loans allow early payoff, but only a written confirmation guarantees extra payments will actually shorten the loan.
- Rate-shop inside a short window. Multiple personal-loan inquiries within a 14–45 day period generally count as a single hard inquiry for credit scoring, so compare at least three lenders without fear.
Frequently asked questions
How do personal loan payments work?
Personal loans are fixed-rate installment loans: you receive a lump sum and repay it in equal monthly payments over 1–7 years. The payment covers principal plus interest, amortized so the balance hits zero on the last payment.
What is an origination fee?
A one-time fee many lenders charge for processing the loan, typically 1–8% of the amount, deducted from the cash you're sent. A $15,000 loan with a 5% fee deposits only $14,250 into your account — but you still repay the full $15,000 plus interest.
What APR should I expect on a personal loan?
It depends heavily on credit: strong-credit borrowers may see 7–12%, average borrowers 13–20%, and weaker credit 25–36%. Banks and credit unions often beat online-only lenders, so compare at least three offers.
Is a personal loan better than a credit card for debt?
Often yes for large balances: personal loan APRs are usually far lower than credit card APRs, and the fixed payoff date forces the debt to actually end instead of revolving indefinitely. But it only helps if you stop adding new card debt.
How does taking out a personal loan affect my credit score?
Applying causes a small, temporary dip from the hard inquiry. Once open, on-time payments build positive history and the loan adds to your credit mix — but the new account lowers your average account age, and a high remaining balance can weigh on scores in the early months.
Can I pay off a personal loan early?
Usually yes, and most personal loans carry no prepayment penalty — but confirm it in your loan agreement before counting on it. Paying early wipes out all remaining interest, making it one of the best uses of a windfall such as a bonus or tax refund.
What is the difference between the interest rate and the APR?
The interest rate is the pure cost of borrowing; the APR folds in certain fees — like origination fees — expressed as a yearly rate, which makes it the better comparison tool. When fees differ between offers, compare APRs, or better yet, total cost.
What should I watch out for in 'no credit check' loan offers?
Legitimate lenders always check credit. 'No credit check' or 'guaranteed approval' offers usually mean triple-digit APRs, heavy hidden fees, or outright scams. If your credit is weak, a local credit union or a secured loan is a far safer path than a predatory online lender.
