How it works

Formula and steps

The formula shows how the personal loan calculator turns your inputs into the result. Use it to check the calculation, then follow the example steps to see each part of the math.

Formula & steps

Net funds formula

N = P - F

Use this when the loan includes an origination fee.

N= Estimated amount received after origination fee
P= Loan principal, or amount borrowed
F= Origination fee amount

Personal loan payment formula

M = Pr (1+r) n (1+r) n 1

Use this fixed-rate formula to estimate the monthly repayment.

M= Monthly payment
P= Loan principal, or amount repaid
r= Monthly APR as a decimal
n= Total number of monthly payments
  1. 1Enter the loan amount, APR, repayment term in months, and optional origination fee.
  2. 2Convert APR to a monthly rate by dividing by 12.
  3. 3Use the fixed-rate loan formula to calculate the monthly payment.
  4. 4Estimate the origination fee from the loan amount and fee percentage.
  5. 5Subtract the origination fee from the loan amount to estimate net funds received.

Worked examples

A $15,000 personal loan over 36 months at 12% APR has an estimated monthly payment based on the fixed-rate repayment formula.

If a lender charges a 5% origination fee, a $15,000 loan may provide about $14,250 before any other lender-specific deductions.

Common uses

  • Personal loan calculator
  • Personal loan payment calculator
  • Personal loan EMI calculator
  • Origination fee estimate
  • Unsecured loan estimate

Common mistakes

  • Comparing only the monthly payment without checking total interest and total repayment.
  • Confusing APR with a guaranteed lender quote.
  • Forgetting that origination fees can reduce the cash received even when repayment is based on the full loan amount.

Personal loan guide

How personal loan payments are calculated

A personal loan payment is usually based on the amount borrowed, APR, and repayment term. This calculator estimates the fixed monthly payment, total interest, total repayment, payoff date, and amortization schedule.

It can be used as a personal loan calculator, personal loan payment calculator, or personal loan EMI calculator for fixed-rate repayment estimates. The result is not a lender quote and does not guarantee approval, APR, fees, or final loan terms.

APR and monthly payment

APR is entered as an annual rate and converted into a monthly rate for the fixed-payment formula. A higher APR or longer term can increase total interest, even if the monthly payment looks easier to manage.

Origination fee impact

Some personal loans charge an origination fee. This calculator estimates the fee as a percent of the loan amount and shows estimated net funds after the fee. Repayment is still estimated from the full loan amount because many lenders calculate payments that way.

Unsecured loan estimates

Many personal loans are unsecured, meaning the rate and approval terms can depend heavily on credit profile, income, debt-to-income ratio, requested amount, term, state rules, and lender underwriting. Use the calculator to compare scenarios, not as a promise of available terms.
