Examples

• Suppose that you want a $250,000 loan to buy a house. The interest rate is 6.5 percent and you can afford to pay $3,000 per month. How long a mortgage would you need?

  NPer(0.075/12, -3000, 250000) - Returns 118.08 (rounded to 2 decimals) months.

• Rather than seeking a loan, suppose that you want to save $500,000 and then buy the house. You can get a 6.5 percent interest rate compounded monthly from your savings plan, and you want to save $3,000 per month. How long would you need to save before you had the required amount of money?

  NPer(0.065/12, -3000, 0, 250000) - Returns 68.96 (rounded to 2 decimals) months.
