Personal Loan Calculator: Estimate Your Monthly Payment

Calculator and loan documents

Wondering how much your monthly payment will be on a personal loan? Our simple calculator takes your loan amount, term, and interest rate to give you an instant estimate—so you can budget with confidence.

Table of Contents

1. How the Calculator Works

The calculator uses the standard amortization formula to determine your fixed monthly payment based on:

  • Loan principal (amount borrowed)
  • Annual Percentage Rate (APR)
  • Loan term in months

2. Required Inputs

  • Loan Amount: Total amount you plan to borrow.
  • APR: The annual interest rate.
  • Term: Length of the loan in months or years.

3. Step-by-Step Example

For a $10,000 loan at 8% APR over 3 years (36 months):

  1. Convert APR to monthly rate: 0.08 / 12 = 0.006667
  2. Apply the formula: Payment = P × r / (1 − (1 + r)−n) where P = 10,000; r = 0.006667; n = 36
  3. Monthly payment ≈ $313.36

4. Tips for Accurate Estimates

  • Include any origination fees, which reduce your net proceeds.
  • Round your APR to two decimal places for the most precise result.
  • Double-check your loan term—shorter terms raise payments but reduce total interest.
