How to Use This Calculator

1

Apply & Get Approved

Lenders evaluate your credit score, income, debt-to-income ratio, and employment history to determine your rate and loan amount.

2

Receive Funds (Minus Fees)

After approval, the lender disburses your loan amount minus any origination fee. A $10,000 loan with a 3% fee means you receive $9,700.

3

Make Fixed Monthly Payments

You repay the full loan amount plus interest in equal monthly installments over the agreed term, typically 12 to 60 months.

4

Pay Off Early (Optional)

Most personal loans allow early payoff without penalty. Extra payments reduce your principal faster, saving interest and shortening your term.

Formula & Methodology

Key Formulas

Monthly Payment
M = P × r(1+r)n / [(1+r)n − 1]
P = principal, r = monthly rate, n = number of payments
Total Interest
Total Interest = (M × n) − P
Sum of all payments minus the original loan amount
Origination Fee
Fee = P × Fee%
Deducted from proceeds; you receive P − Fee
Effective APR
APR accounts for fees over loan term
Higher than stated rate when origination fee is charged

Glossary

APRAnnual Percentage Rate. The yearly interest rate charged on borrowed money, not including compounding.
Origination FeeA one-time fee (1-8%) charged by the lender for processing your loan, deducted from your loan proceeds.
AmortizationThe process of paying off a loan in equal installments, where each payment covers interest and principal.
PrincipalThe original amount borrowed, excluding interest and fees.
Effective APRThe true annual cost of borrowing when origination fees are factored in, always higher than the stated APR.
Unsecured LoanA loan not backed by collateral. Personal loans are typically unsecured, resulting in higher rates than secured loans.

Personal Loan is a fundamental concept that this calculator helps you understand and apply. Whether you're a beginner or experienced professional, having precise calculations at your fingertips saves time and reduces errors.

  • Compare scenarios — try different input combinations to understand how each variable affects the outcome.
  • Save your work — use the Share button to bookmark specific calculations for future reference.
  • Consult professionals — for critical decisions, use calculator results as a starting point and verify with a qualified expert.

Frequently Asked Questions

Basics How is my personal loan monthly payment calculated?
Your monthly payment is calculated using the standard amortization formula: M = P × [r(1+r)n] / [(1+r)n − 1]. P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments. Each payment is split between interest (on the remaining balance) and principal reduction.
Basics What is an origination fee and how does it affect my loan?
An origination fee is a one-time charge (typically 1-8% of the loan amount) that the lender deducts from your proceeds before disbursement. For example, a $10,000 loan with a 3% origination fee means you receive $9,700 but still repay the full $10,000 plus interest. This increases your effective APR above the stated interest rate.
Basics What is a good interest rate for a personal loan?
Personal loan rates typically range from 6-36% APR depending on your credit score. Excellent credit (750+) may qualify for 6-10%, good credit (700-749) for 10-15%, fair credit (640-699) for 15-23%, and poor credit may see rates of 24% or higher. Always compare offers from multiple lenders.
Strategy How do extra payments reduce my personal loan cost?
Extra payments go directly toward reducing your principal balance. With a lower balance, less interest accrues each month, which means more of each subsequent payment goes to principal. This creates a compounding effect that shortens your payoff time and can save you hundreds or thousands in total interest.
