A fixed-rate mortgage payment may stay the same from month to month, but the way that payment is divided between interest and principal changes over time. That changing split is the basic idea behind mortgage amortization.
Read guide →Business & InvestingReturn on investment, or ROI, compares the gain from an investment with the amount invested. It is popular because the formula is simple and can be applied to many business, marketing and personal-finance decisions.
Read guide →Start with the decision you need to make. For a loan, compare the monthly payment against your budget rather than judging only the interest rate. For example, a $12,000 balance at 6% annual simple interest would accrue $720 in interest over one year; a fully amortizing loan uses a different payment calculation. For savings, distinguish a quoted annual percentage rate from APY, which accounts for compounding. Mortgage payment estimates generally exclude property taxes and insurance unless those amounts are specifically entered.
