Formula Used

The calculator uses the following formulas to determine your monthly housing costs:

Monthly Mortgage Payment = P * (r(1+r)^n) / ((1+r)^n - 1)

Where:

P = Principal loan amount (Home Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12 / 100)
n = Number of payments (Loan Term in Years * 12)

The total monthly housing cost is calculated by adding:

Monthly mortgage payment
Monthly property taxes (Annual Property Taxes / 12)
Monthly homeowners insurance (Annual Insurance / 12)
Monthly maintenance expenses

Worked Example

Let's calculate the monthly housing costs for a $300,000 home with these assumptions:

Down payment: 20% ($60,000)
Loan term: 30 years
Interest rate: 4.5%
Annual property taxes: $3,600
Annual homeowners insurance: $1,200
Maintenance expenses: $1,000/month

Step 1: Calculate the principal loan amount

$300,000 - $60,000 = $240,000

Step 2: Calculate the monthly mortgage payment

Monthly interest rate = 4.5% / 12 = 0.00375

Number of payments = 30 * 12 = 360

Monthly payment = $240,000 * (0.00375(1+0.00375)^360) / ((1+0.00375)^360 - 1)

Monthly payment ≈ $1,424.32

Step 3: Calculate other monthly costs

Property taxes: $3,600 / 12 = $300/month
Homeowners insurance: $1,200 / 12 = $100/month
Maintenance: $1,000/month

Step 4: Calculate total monthly housing cost

$1,424.32 (mortgage) + $300 (taxes) + $100 (insurance) + $1,000 (maintenance) = $2,824.32/month

Your total monthly housing cost would be approximately $2,824.32 based on these assumptions.
