  • Most loans (mortgage and other) in the United States compound interest monthly.
  • Mortgage loans in Canada compound interest semi-annually.
  • 30 years=360 months
  • 25 years=300 months
  • 20 years=240 months
  • 15 years=180 months
  • 10 years=120 months
  •   5 years=  60 months
  •   3 years=  36 months

  1. If you want to calculate how much a mortgage payment would be on a $200,000 mortgage at 5% interest for 360 months (30 years), you would enter:
    • 200000 (or 200,000) for the Loan Amount
    • 360 for Months
    • 5 for Interest Rate (Compounded Monthly)
    • Press the Payment button, and you'll see that your payment would be $1,073.64.
    • Note: If you look down the amortization schedule, you'll see the final payment is $1,076.47.  Some lenders don't like the final payment to be greater than the regular payment so they'll add a penny to the regular payment.  You can do that on this calculator simply by adding a penny to the payment and solving for "Months".  The # of months won't change much, if at all.  Now you can view the schedule again to see the difference it makes.  In this case, you'll make 359 full payments of $1,073.65 and a final payment of $1,068.30.
  1. Using the example above, let's say you can make a higher monthly payment.  You would like to round your payment up to $1,200/month.  How long will it take to pay off your mortgage?
    • Leave everything the same, just enter 1200 for Payment and press Months.
    • It will take only 286 months to pay off your mortgage! (285 full payments of $1,200 and a final partial payment of $170.76)
    • So paying that extra $126.36/month will save you a little more than 6 years of payments, and about $44,342 interest!
  1. Suppose you want to buy a car, but you don't want to spend more than $250/month for payments.  You can get a 4 year car loan at 3.9%.  How much of a car can you buy?  You would enter:
    • 48 for Months
    • 3.9 for Interest Rate (compounded Monthly)
    • 250 for Monthly Payment
    • Press the Principal button, and you will see that you could buy a $11,094.18 car with no down payment -or put more money down on a more expensive car.
