Why is there so much interest on home loans?
Interest rates are always given annually, to make them comparable. If you prefer to calculate the rate or the total interest for the complete time, like 10 years or 15 years or 30 years, it is simple math, and it tells you the total you will pay, but it is not helpful for picking the better or even the right offer for your situation. Compare it to your car's gas mileage- what sense does it make to provide the information that a car will use 5000 gallons of gas over its lifetime? Is that better than a car that uses 6000 gallons (but may live 2 years longer?)
