Calculating the Price of a Home with a Fixed Mortgage

Understanding the Problem

You have just been approved for a 30-year, 5.5% fixed home mortgage with a monthly payment of $532.10. The goal is to determine the price of a home that can be purchased using this mortgage. To solve this problem, we need to use the formula for calculating the monthly payment on a fixed-rate mortgage.

Formula for Monthly Payment

The formula for calculating the monthly payment on a fixed-rate mortgage is:

M = P[r(1+r)^n]/[(1+r)n – 1]

Where:

M = monthly payment
P = principal loan amount (the price of the home)
r = monthly interest rate (annual interest rate divided by 12)
n = number of payments (30 years * 12 months/year = 360 months)

Given Values

Monthly payment (M) = $532.10
Annual interest rate (r) = 5.5% = 0.055
Number of payments (n) = 360 months

Calculating the Monthly Interest Rate

To use the formula, we need to calculate the monthly interest rate (r). This is done by dividing the annual interest rate by 12:

r = 0.055 / 12 = 0.004583

Rearranging the Formula to Solve for P

To solve for the principal loan amount (P), we need to rearrange the formula:

P = M[(1+r)^n – 1]/[r(1+r)^n]

Plugging in the Values

Now we can plug in the given values into the rearranged formula:

P = 532.10[(1+0.004583)^360 – 1]/[0.004583(1+0.004583)^360]

Calculating the Price of the Home

Using a calculator to evaluate the expression, we get:

P ≈ $194,919.19

Rounding the Answer

Rounding the answer to the nearest dollar, we get:

P ≈ $194,919

Conclusion

Based on the given monthly payment of $532.10 and a 30-year, 5.5% fixed home mortgage, the price of a home that can be purchased is approximately $194,919.

Table of Values

Mortgage Term	Annual Interest Rate	Monthly Payment	Price of Home
30 years	5.5%	$532.10	$194,919

Example Use Case

This calculation can be used to determine the price of a home that can be purchased with a fixed-rate mortgage. For example, if you are considering purchasing a home and have been approved for a 30-year, 5.5% fixed mortgage with a monthly payment of $532.10, you can use this calculation to determine the price of the home.

Tips and Variations

This calculation assumes a fixed interest rate and a 30-year mortgage term. If the interest rate or mortgage term is different, the calculation will be different.
This calculation does not take into account other costs associated with purchasing a home, such as closing costs and property taxes.

Q&A

Q: What is the formula for calculating the monthly payment on a fixed-rate mortgage?

A: The formula for calculating the monthly payment on a fixed-rate mortgage is:

M = P[r(1+r)^n]/[(1+r)n – 1]

Where:

M = monthly payment
P = principal loan amount (the price of the home)
r = monthly interest rate (annual interest rate divided by 12)
n = number of payments (30 years * 12 months/year = 360 months)

Q: What is the monthly interest rate (r)?

A: The monthly interest rate (r) is calculated by dividing the annual interest rate by 12. In this case, the annual interest rate is 5.5%, so the monthly interest rate is:

r = 0.055 / 12 = 0.004583

Q: How do I calculate the price of the home (P)?

A: To calculate the price of the home (P), we need to rearrange the formula:

P = M[(1+r)^n – 1]/[r(1+r)^n]

Then, we can plug in the given values into the rearranged formula:

P = 532.10[(1+0.004583)^360 – 1]/[0.004583(1+0.004583)^360]

Q: What is the price of the home (P)?

A: Using a calculator to evaluate the expression, we get:

P ≈ $194,919.19

Rounding the answer to the nearest dollar, we get:

P ≈ $194,919

Q: What are some other costs associated with purchasing a home that I should consider?

A: In addition to the price of the home, you should also consider other costs associated with purchasing a home, such as:

Closing costs: These are fees associated with the home buying process, such as title insurance, appraisal fees, and attorney fees.
Property taxes: These are taxes levied on the value of the home.
Homeowners insurance: This is insurance that protects the home and its contents from damage or loss.
Maintenance and repairs: These are costs associated with maintaining and repairing the home.

Q: How do I determine the price of a home that I can afford?

A: To determine the price of a home that you can afford, you should consider the following factors:

Your income: How much money do you have available each month to put towards a mortgage payment?
Your debt: Do you have any other debts, such as credit card debt or student loans, that you need to consider?
Your credit score: A good credit score can help you qualify for a lower interest rate on your mortgage.
Your down payment: The amount of money you put down on the home can affect the price of the home you can afford.

Conclusion

Calculating the price of a home with a fixed mortgage can be a complex process, but by using the formula and considering other costs associated with purchasing a home, you can determine the price of a home that you can afford. Remember to also consider other factors, such as your income, debt, credit score, and down payment, to ensure that you are making an informed decision.
