Personal Loan Calculator

Calculate personal loan payments, total interest, and total cost. Compare terms from 12–84 months with optional origination fee impact on true cost.

About the Personal Loan Calculator

A personal loan is an unsecured, fixed-rate loan that you repay in equal monthly installments over a set term. Banks, credit unions, and online lenders offer personal loans for debt consolidation, home improvements, medical expenses, and virtually any other purpose.

Because personal loans are unsecured — no collateral required — interest rates are typically higher than secured loans like mortgages or auto loans. Rates range from about 6% for excellent credit to 36% for subprime borrowers. The term, usually 12 to 84 months, also affects your monthly payment and total interest.

This Personal Loan Calculator shows your monthly payment, total interest, and total cost for any amount, rate, and term. It also includes an optional origination fee toggle that reveals the true cost of borrowing after upfront fees are deducted from your loan proceeds. By adjusting the term length and comparing different rate offers, you can find the repayment plan that balances affordable monthly payments with the lowest possible total interest cost.

Why Use This Personal Loan Calculator?

Comparing personal loan offers requires more than looking at interest rates. Origination fees (typically 1–8% of the loan), term length, and total cost all affect the real price of borrowing. This calculator exposes the full picture so you can choose the loan that truly costs the least. Even a small rate difference can translate into hundreds of dollars over a multi-year term.

How to Use This Calculator

  1. Enter the loan amount you need to borrow.
  2. Set the annual interest rate from your lender quote.
  3. Choose a repayment term in months (12–84).
  4. Optionally enter an origination fee percentage to see its impact.
  5. Review your monthly payment, total interest, and total cost.
  6. Adjust the term to see how shorter or longer periods change the payment and total cost.

Formula

Monthly Payment M = P × r(1+r)^n / ((1+r)^n − 1), where P = loan amount, r = monthly rate, n = months. Total Interest = (M × n) − P. With origination fee: Net Proceeds = P × (1 − fee%). Effective rate is higher because you repay the full amount but receive less.

Example Calculation

Result: $383.98/month — $3,431 total interest — $450 origination fee

A $15,000 loan at 10.5% for 48 months produces a $383.98 monthly payment. Total payments are $18,431, so total interest is $3,431. The 3% origination fee ($450) is deducted from proceeds — you receive $14,550 but repay $18,431, making the true cost $3,881.

Tips & Best Practices

How Personal Loans Work

You apply for a specific amount, receive a rate quote based on your creditworthiness, and choose a term. Once approved, the lender deposits funds (minus any origination fee) into your account. You make fixed monthly payments until the loan is fully repaid.

The Impact of Origination Fees

An origination fee reduces your actual proceeds while keeping your repayment amount the same. This effectively raises the annual percentage rate (APR) above the stated interest rate. When comparing offers, always look at the APR — it includes the fee impact — rather than the interest rate alone.

When to Use a Personal Loan

Personal loans work best for debt consolidation (replacing high-rate credit cards), large planned expenses (home renovation, medical procedure), or bridging a temporary cash need. They are less ideal for recurring expenses or when you could save up instead.

Frequently Asked Questions

What is a personal loan?

A personal loan is an unsecured loan with a fixed interest rate and fixed monthly payments over a set term. Unlike mortgages or auto loans, no collateral is required. You can use the funds for almost any purpose — debt consolidation, home improvements, medical bills, or major purchases.

What is a good personal loan interest rate?

Rates depend heavily on your credit score. Excellent credit (750+) may qualify for 6–10%. Good credit (700–749) typically sees 10–15%. Fair credit (650–699) may get 15–24%. Below 650, rates can reach 25–36%. Always compare multiple lender offers to find the best available rate.

What is an origination fee?

An origination fee is an upfront charge (typically 1–8% of the loan amount) deducted from your loan proceeds. If you borrow $10,000 with a 3% fee, you receive $9,700 but repay the full $10,000 plus interest. This increases your effective borrowing cost significantly.

How long should my loan term be?

Choose the shortest term you can comfortably afford. A 36-month term costs much less in total interest than a 60-month term. However, the monthly payment will be higher. Balance affordability with total cost — ideally keeping the payment under 10% of your monthly income.

Can I pay off a personal loan early?

Most personal loans allow early payoff, but some charge a prepayment penalty. Check your loan agreement before signing. Paying early saves interest and frees up your monthly budget sooner. Even small extra payments can reduce total interest significantly.

Is a personal loan better than a credit card?

For large, planned expenses, personal loans are usually better — they have lower rates, fixed payments, and a clear payoff date. Credit cards are better for smaller purchases you can pay off monthly. For existing credit card debt, a personal loan for consolidation often saves money.
