FAQ

Does this include taxes and insurance?+

No. This is principal and interest only. Property taxes, homeowners insurance, and PMI are real costs but vary by location and lender. Add them separately.

Why is so much of the early payment interest?+

Mortgages are amortized so each payment is the same. Early on, the loan balance is high so most of the payment is interest. Late in the loan, the balance is low so most of the payment is principal.
