The Short Version

A personal loan is a lump sum borrowed from a bank, credit union, or online lender, repaid in fixed monthly installments over a set term, usually at a fixed interest rate. Unlike a mortgage or auto loan, it's typically 'unsecured,' meaning it isn't backed by a specific asset the lender can repossess — which usually means higher interest rates than secured loans, since the lender is taking on more risk.

Explain It Like I'm 10

Imagine borrowing $1,000 from a relative to buy a used laptop, and agreeing to pay them back $100 a month for just under a year, with a little extra added on top as a thank-you for the loan. That's a personal loan: a fixed amount borrowed, repaid on a fixed schedule, with the 'thank-you extra' being the interest — except a bank, not a relative, is the one lending it, and they don't take your laptop back if you miss a payment (though they can still pursue you for the debt).

Step-by-Step Example

  1. 1 You borrow a $6,000 personal loan at 10% annual interest, to be repaid over 3 years.
  2. 2 The lender calculates a fixed monthly payment (roughly $194/month) that covers both principal and interest over the term.
  3. 3 Each month, part of your payment reduces the amount owed (principal) and part covers interest on the remaining balance.
  4. 4 Over the full 3 years, you'll pay back the original $6,000 plus roughly $980 in total interest — the exact cost of borrowing.
  5. 5 Because the rate and term are fixed, you know the total cost upfront, unlike a credit card balance where the cost keeps changing based on how much and how fast you pay it down.

Quick Recap

  • ✓ Unsecured: not backed by collateral, unlike a mortgage (backed by the house) or auto loan (backed by the car).
  • ✓ Fixed monthly payments over a fixed term make budgeting predictable, unlike credit card debt with variable minimum payments.
  • ✓ Often used to consolidate higher-interest debt (like several credit cards) into one loan at a single, often lower, rate.
  • ✓ Interest rates depend heavily on credit score — the same loan amount can cost very different amounts to different borrowers.
