Personal Loan Calculator

How to use this calculator

Enter the loan amount you're considering, the interest rate (use the APR if you have it — more on that below), and the loan term in months. The result is the fixed monthly payment and the total interest you'll pay over the life of the loan. Run it a few times with different term lengths to see how extending or shortening the repayment period changes both the monthly obligation and total cost.

If you've received a loan offer, use the APR from the offer document rather than the stated interest rate. The APR includes fees rolled into the effective rate, making it a more accurate basis for comparison across lenders. A loan advertised at 10% interest with a 3% origination fee has a higher effective APR than 10%.

What your result means

Personal loans are fixed-rate, fixed-term installment loans — the monthly payment doesn't change, the loan has a defined end date, and you know exactly how much you'll pay in total interest from the start. That predictability is one of their main advantages over revolving credit like credit cards or HELOCs.

The total interest figure puts the full cost of the loan in plain view. A $10,000 personal loan at 12% over 36 months costs about $1,957 in interest. The same loan over 60 months costs about $3,333 in interest — 70% more — even though the monthly payment is lower. Shorter terms are cheaper; longer terms are more affordable month-to-month. That tradeoff is what this calculator makes visible.

What the math leaves out

This calculator doesn't include origination fees, which most personal loan lenders charge — typically 1–8% of the loan amount deducted upfront. If you borrow $10,000 with a 5% origination fee, you receive $9,500 but repay $10,000 plus interest. Always ask about origination fees and factor them into your comparison. Some lenders advertise low rates but high fees; others do the reverse.

Prepayment penalties are another variable this calculator doesn't capture. Most personal lenders allow early payoff without penalty, but some charge a fee. If you might pay the loan off early, confirm there's no penalty before signing.

When a personal loan makes sense

Personal loans work best for defined, one-time expenses where you want a predictable payoff timeline: consolidating high-rate credit card debt, funding a home improvement project without tapping equity, covering a large medical bill, or financing a major purchase. They work less well for ongoing expenses (a revolving credit line fits better) or for purchases where secured financing (auto loans, mortgages, HELOCs) would offer significantly lower rates.

Frequently asked questions

What credit score do I need for a personal loan?
Most lenders have a minimum of around 600–640 for approval, but rates at those scores are high (18–30%). To qualify for competitive rates (7–12%), you generally need a score of 700 or above. Some credit unions and community banks are more flexible on scores for members, often with rates lower than online lenders at the same score tier.

How fast can I get a personal loan?
Online lenders often fund within 1–3 business days after approval. Traditional banks typically take 5–10 business days. Credit unions can vary widely. If you need funds urgently, online lenders or your existing bank (which already has your account information) are the fastest paths.

Is a personal loan better than a credit card for a big purchase?
Usually yes, if the purchase is large enough to take more than a few months to pay off. Personal loan rates (even at 15%) are almost always lower than credit card APRs (18–30%), and the fixed payment structure means you'll actually pay it down rather than making minimum payments indefinitely. For purchases you can pay in full within a billing cycle, a credit card with rewards is better.
