Frequently Asked Questions
What is PMI and when do I stop paying it?▾
PMI (private mortgage insurance) protects the lender when your down payment is under 20% of the home price. It is typically cancelled automatically once your equity reaches 20%, so this calculator charges it only when the loan-to-value ratio exceeds 80%.
Why is my total payment higher than the interest rate suggests?▾
The mortgage interest rate only covers the borrowed amount. Property tax, home insurance and PMI are added on top and are usually collected monthly with your payment, making the true monthly cost noticeably higher.
How do extra mortgage payments help?▾
Extra principal payments — a monthly top-up or a one-time lump sum — immediately reduce the balance that accrues interest. This shortens the mortgage term and can save a substantial amount of interest over the life of the loan.
