Purchase Calculator — full PITI with PMI and early-payoff scenarios
Estimate your monthly mortgage payment with principal, interest, taxes, insurance, HOA, and PMI. Model extra payments and lump-sum payoff.
What will my monthly mortgage payment be?
The Purchase Calculator estimates your full monthly mortgage payment — principal, interest, taxes, insurance, HOA, and PMI when down payment is below 20% — and models how extra monthly payments or a one-time lump sum shorten your payoff. Use it to size a Conventional purchase loan and stress-test early-payoff strategies.
Frequently asked questions
When is PMI required?+
Private mortgage insurance is required on Conventional loans whenever the down payment is less than 20%. The calculator auto-applies a typical PMI rate so your monthly estimate reflects reality.
How much can extra payments save?+
Adding even $100–$200/month to principal on a 30-year loan can shave years off the term and tens of thousands in interest. Use the extra-payment input to see the exact impact on your loan.
What's included in PITI?+
PITI is Principal, Interest, Taxes, and Insurance — the four components of a standard mortgage payment. Many lenders also include HOA dues and PMI in the monthly figure, which this calculator does.
