Key Elements Needed to Calculate Mortgage Payments

Loan amount or principal

The loan principal, often denoted as P in the mortgage formula, is the loan amount itself. This amount is the original loan amount, not including any interest. For example, if you purchase a $350,000 home and put down $50,000 in cash, you’re borrowing $300,000 of principal from the lender, which you’ll need to pay back over the length of the loan.

The annual interest rate on the loan, denoted as r in the mortgage formula, is the monthly amount that the lender charges you on top of the principal. It’s crucial to remember that this is not necessarily the Annual Percentage Rate (APR) because the mortgage is paid monthly, not annually, which creates a slight difference between the APR and the interest rate.

The loan’s term (number of years to repay) The term, symbolized as t in the mortgage formula, refers to the number of years you must repay the loan. For instance, most home loans are either 15-year or 30-year terms.

Number of payments per year Usually denoted as n in the mortgage formula, this is the number of payments per year. For most mortgages, this would be 12 for monthly payments

Explanation of the Formula

1. P represents the principal or loan amount. As stated before, P represents the original amount of the loan or the principal that you have borrowed from the lender.
2. r represents the annual interest rate as a decimal. This is the yearly interest rate charged by the lender, divided by the number of payments made in a year to get the monthly interest rate. It’s represented as a decimal in the formula, meaning an annual interest rate of 4% would be input as 0.04.
3. n represents the number of payments per year. For a typical mortgage where payments are made monthly, n equals 12. However, this could change if the payments are made on a different schedule.
4. t represents the loan’s term in years. This is the term or duration of the loan in years. For example, a standard 30-year mortgage would have a t value 30.

The mortgage payment formula is: Payment = P * (r / n) * (1 + r / n)^(nt)] / (1 + r / n)^(nt) – 1
This formula calculates your monthly payment by multiplying the principal amount with the monthly interest rate and the ratio of the compounded interest over the loan term to the subtraction of one from the compounded interest.

Monthly Interest and Principal Components

Explanation of how payments are divided between interest and principal. Each mortgage payment comprises two main components: principal and interest. The principal component is the portion of the payment that reduces the original loan amount. On the other hand, the interest component is the fee charged by the lender for borrowing the money. The exact amounts going towards principal and interest change with each payment in a process known as amortization. In the early years of the loan, the majority of the payment goes toward interest. As time progresses, a more significant portion of the payments goes toward reducing the principal.

Amortization

Introduction to the concept of amortization is the process of paying off debt, like a mortgage, over time through regular payments. A portion of each payment is for interest, and the remaining amount is applied toward the principal balance. The exact amount applied to principal versus interest varies throughout the term of the loan, with more of your payment going to interest in the early stages of your loan repayment schedule and gradually shifting towards more principal repayment later in the loan term.

Additional Costs

Mention of other costs often included in monthly payments. It’s essential to note that your total monthly mortgage payment usually has more than just the principal and interest. Other costs are often incorporated, such as property taxes and homeowners’ insurance, typically held in an escrow account. Additionally, if your down payment is less than 20% of the home’s purchase price, you’ll likely have to pay mortgage insurance, either private mortgage insurance (PMI) or a mortgage insurance premium (MIP) for FHA loans.
