Formula Used
The Money Guy House Calculator uses the following formulas to calculate the various components of your home investment:
Monthly Mortgage Payment
M = P [i(1 + i)^n] / [(1 + i)^n - 1]
Where:
- M = Monthly mortgage payment
- P = Principal loan amount (Purchase Price - Down Payment)
- i = Monthly interest rate (Annual Interest Rate / 12 / 100)
- n = Number of payments (Loan Term in years × 12)
Total Interest Paid
Total Interest = (Monthly Mortgage Payment × Number of Payments) - Principal Loan Amount
Total Property Tax
Total Property Tax = (Purchase Price × Property Tax Rate) / 100
Total Insurance
Total Insurance = Insurance Cost × Loan Term
Total Maintenance
Total Maintenance = Maintenance Cost × Loan Term
Total Investment
Total Investment = Down Payment + Total Interest + Total Property Tax + Total Insurance + Total Maintenance
Worked Example
Let's walk through an example to see how the Money Guy House Calculator works. Suppose you want to buy a house with the following details:
- Purchase Price: $300,000
- Down Payment: 20% ($60,000)
- Interest Rate: 4.5%
- Loan Term: 30 years
- Property Tax Rate: 2.5%
- Insurance: $1,200 per year
- Maintenance: $3,000 per year
Using the calculator with these inputs, you would get the following results:
| Metric | Value |
|---|---|
| Monthly Mortgage Payment | $1,425.36 |
| Total Interest Paid | $204,207.00 |
| Total Property Tax | $18,000.00 |
| Total Insurance | $36,000.00 |
| Total Maintenance | $90,000.00 |
| Total Investment | $390,207.00 |
This example shows that buying this house would require a total investment of $390,207 over 30 years, including the down payment, interest, property taxes, insurance, and maintenance costs.
