Frequently Asked Questions
What inputs does the calculator need?
The required inputs are home price, down payment percentage, annual interest rate, and loan term in years. Monthly property tax, homeowners insurance, and HOA fee are optional fields that add to the all-in monthly payment total without affecting the amortization calculation.
How does the loan term affect my payment and total cost?
A 30-year term produces a lower monthly payment but results in significantly more total interest paid over the life of the loan. A 15-year term roughly doubles the monthly payment on the same loan amount but typically cuts total interest by 50% or more because the principal is paid down twice as fast.
Does the calculator include property taxes and insurance?
Yes. Enter your estimated monthly property tax, homeowners insurance, and HOA fee in the optional fields. The calculator adds these to the principal and interest payment and shows both the base P+I and the total all-in monthly cost.
What is an amortization schedule?
An amortization schedule is a month-by-month table showing how each payment is divided between principal reduction and interest cost, and what the remaining loan balance will be after that payment. In the early years, most of each payment is interest; this ratio gradually shifts toward principal as the balance decreases.
What does the refinance breakeven tell me?
The breakeven point is the number of months you need to stay in the home after refinancing before the accumulated monthly savings exceed the one-time closing costs. If you plan to sell or move before that point, refinancing likely costs more than it saves. A breakeven under 24 months is generally considered favorable.
What is PMI and when is it required?
Private Mortgage Insurance (PMI) is required by most lenders when your down payment is less than 20% of the home price, meaning the loan-to-value ratio exceeds 80%. PMI typically costs 0.5% to 1.5% of the loan amount per year. You can model its cost by adding the monthly PMI amount to the insurance field.
Can I compare a 15-year vs. 30-year mortgage?
Yes. Run the calculator twice with the same inputs but different term values. The Insights tab shows total interest paid and the full loan summary for each scenario, making it straightforward to compare lifetime cost against the difference in monthly payment.
