What is the difference between interest rate and APR?

The interest rate reflects the cost of borrowing the principal. APR typically includes fees and other costs, making it a better number for comparing loan offers.

How do I compare two loans correctly?

Compare monthly payment, total interest paid, and total cost. If fees differ, compare APR as well so you are comparing the true cost of borrowing.

Does a longer term always mean a cheaper loan?

A longer term usually lowers the monthly payment, but it often increases the total interest paid. Shorter terms cost more per month but can reduce total cost significantly.

Can I save money by making extra payments?

Yes. Extra payments reduce principal faster, which reduces future interest. The impact is larger early in the loan when the balance is highest.

Formula

M = P × [ i(1 + i)^n ] / [ (1 + i)^n − 1 ]

Where:

M = monthly payment
P = principal (loan amount)
i = monthly interest rate (annual / 12)
n = number of monthly payments

Total Interest ≈ (M × n) − P.
