Frequently Asked Questions

How is the monthly payment calculated?

Using the standard amortization formula M = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan principal, r is the monthly interest rate (annual ÷ 12), and n is the total months. Each payment covers interest accrued plus a portion of principal.

What is PMI and when do I need it?

Private Mortgage Insurance (PMI) is typically required when your down payment is less than 20% of the home price. It protects the lender if you default. Costs run roughly 0.5–1.5% of the loan annually. Once you reach 20% equity you can request removal.

15-year vs 30-year mortgage — which is better?

A 15-year loan has higher monthly payments but significantly less total interest and faster equity growth. A 30-year loan offers lower monthly payments and better cash flow flexibility. Toggle between them above to compare.

What does the amortization schedule show?

It breaks down every year of the loan into principal paid, interest paid, and remaining balance. Early payments are mostly interest; over time more goes to principal as the balance shrinks.
