Equation for mortgage payments

M = P[r(1+r)^n/((1+r)^n)-1)]

  • M – Your total monthly payment
  • P – This represents the principal amount on your mortgage.
  • r – This is your monthly interest rate. Most mortgage lenders offer an annual rate. Divide this rate by 12 to get your monthly interest rate.
  • n – This represents the number of payments you’ll make over the duration of your loan. Your loan term will be given in years (i.e. a 15 or 30 year loan), however, you’ll be making monthly payments. Multiply your loan term by 12 to find out the number of payments you will make. For example, a 30 year loan term, divided by 12 payments per year, equals 360 total payments.


Glossary of terms

Home Price

The sum for which a home is bought or sold. This does not include the extra payments made to third parties or the other costs of buying and owning a property.

Down Payment

A down payment covers a certain percentage of the purchase price of a house that you pay upfront. If you buy a home, a down payment can range from 5% to 25% of the home’s total value, and a bank or other lender covers the rest of the cost. A higher down payment decreases the amount of interest paid when you pay the regular installments on your loan.

Mortgage Rate

The amount of interest paid on a mortgage. Mortgage interest rates can stay fixed or can fluctuate. If the purchaser has a high credit score, the lender lowers the rate because they risk less by loaning the money. The risk and rate correlate: the higher the risk of loaning the money, the higher the mortgage interest rate.

Loan Term

Loan term refers to the amount of time the borrower follows the mortgage agreement, including the interest rate, regular payments, and other specific conditions upon which the mortgage was granted.

Principal and Interest

Principal and interest make up the bulk of your mortgage payment. Principal is the part of your mortgage that gets applied to the value of your home, and interest is a fee paid to the bank for financing your loan.

Homeowners Insurance

Homeowners insurance is commonly rolled into escrow. Although not required by law, acquiring homeowners insurance is common practice in the home buying process and is highly recommended to cover any unforeseen damage or loss.

Property Taxes

Charged on immovable property, including land and structures that are permanently attached to the ground, such as a house or building. When you buy a home, you must pay real estate taxes, also known as property taxes, directly to your local tax assessor or indirectly as part of your monthly mortgage payment.


Stands for private mortgage insurance, which is a type of mortgage insurance you could be required to pay for if you have a conventional loan. PMI is typically required when you obtain a conventional mortgage and make a down payment of less than 20 percent of a home’s purchase price.

HOA Fees

Required by some condominiums and neighborhoods as part of a homeowners’ association (HOA). Dues are typically paid directly to the homeowners’ association (HOA) and are not included in the payment you make to your mortgage servicer.
