What Is a Loan? Quick Definition and How Loans Work (Detailed Guide)
A loan is borrowed money from a lender (bank, credit union, online platform) that you repay over time, plus interest--the cost of borrowing. Loans help fund big purchases like homes, education, or business growth, but mismanagement leads to debt traps.
Core Mechanics for Beginners
Loans work via principal (amount borrowed), interest (fee based on principal and time), and repayment schedule. Most use amortized interest, where payments cover interest first, then principal, reducing the balance over time. Simple interest (common in student loans) is easier: Interest = Principal × Rate × Time.
- Formula for Amortized Payment (from Colorado State University Extension):
B = (i × A) / [1 – (1 + i)^(-N)]
Where:- B = periodic payment
- i = periodic interest rate (annual rate / periods per year)
- A = loan amount (principal)
- N = total periods
2026 Example (Bankrate): A $340,000 30-year mortgage at 7% interest yields monthly payments with $474,330 total interest--nearly 140% of principal. Use Bankrate's calculator for your scenario.
Repayment builds equity but front-loads interest. Early payments are mostly interest; later ones shift to principal.
