Personal loans are usually unsecured with fixed rates from about 7% to 36% depending on credit. Many lenders deduct an origination fee of 1–10% from the loan, so you receive less than you borrow – the real APR shows the full cost.

How to use the Personal Loan Calculator

  1. Loan amount
  2. Interest rate (APR)
  3. Loan term
  4. Origination fee (% of loan)

Results update as you type, and every field accepts the units shown in its menu.

How it works

Enter the loan amount, interest rate and term and the origination fee.

Tips

  • Compare loans by APR and total cost, not just the monthly payment.
  • Extra payments go straight to principal and can save a lot of interest.
  • Pay off the highest-rate debt first if you want to save the most money.
  • Check for prepayment penalties before paying a loan off early.

Common mistakes to avoid

  • Stretching a loan term to lower the payment without seeing the extra interest.
  • Paying only the minimum on credit cards.
  • Forgetting fees that are rolled into the loan.

Inputs explained

Loan amount Amount in your currency
Interest rate (APR) In %
Loan term Units: years, months
Origination fee (% of loan) In %

What each result means

  • Monthly payment = pmt([Interest rate (APR)]÷1200, [Loan term], [Loan amount])
  • Total interest = [Monthly payment]×[Loan term] – [Loan amount]
  • Total of all payments = [Monthly payment]×[Loan term]
  • Origination fee = [Loan amount]×[Origination fee (% of loan)]÷100
  • Money you receive = [Loan amount] – [Origination fee]
  • Real APR including the fee = rate([Loan term], 0 – [Monthly payment], [Loan amount] – [Origination fee])×1200

Example values

How the main result changes when Loan amount changes and everything else stays at the example values above:

Loan amount Monthly payment
7,500 193.84
11,250 290.76
15,000 387.68
18,750 484.6
22,500 581.52
30,000 775.37

Formula

Monthly payment = L × i ÷ (1 − (1 + i)^−n), i = APR ÷ 12, n = monthsTotal interest = payment × n − LAPR with fees: the rate at which (L − fee) equals the present value of the payments

Worked example

Inputs — Loan amount: $15,000; Interest rate (APR): 11 %; Loan term: 4 years; Origination fee (% of loan): 4 %.
Results — Monthly payment = $387.68; Total interest = $3,608.78; Total of all payments = $18,608.78; Origination fee = $600.00; Money you receive = $14,400.00; Real APR including the fee = 13.191 %.
