This guide is for general education only. PMI rules, lender pricing, taxes, insurance, and loan programs vary. Confirm final costs with lender disclosures and qualified professionals.
PMI is a monthly cost, not just a checkbox
Many buyers compare 5%, 10%, and 20% down payments only by cash needed upfront. A better comparison includes PMI, monthly payment pressure, emergency reserves, closing costs, and how quickly the loan balance may fall below the PMI removal threshold.
Down payment size
A smaller down payment can preserve cash, but it usually increases the loan amount and may add PMI.
Monthly PMI
PMI is often paid monthly, so it should be included with principal, interest, taxes, insurance, and HOA.
Cash reserves
Putting every dollar into the down payment may reduce PMI but leave too little cash after closing.
Removal timing
Understand when PMI may be canceled or removed based on loan balance, home value, payment history, and lender rules.
A practical PMI comparison
1. Compare several down payments
Run at least 5%, 10%, and 20% down scenarios so you can see loan amount, monthly payment, and cash needed.
2. Add estimated PMI
Use a lender quote or conservative estimate, then include PMI in the full monthly housing payment.
3. Keep closing cash separate
Do not use the down payment as the only cash number. Include closing costs, prepaid items, moving costs, and reserves.
4. Check the exit plan
Ask when PMI can be removed and whether extra payments, appreciation, or refinancing might change the timeline.
Estimate the full payment with PMI
Use the mortgage calculator to compare down payment scenarios, monthly PMI, taxes, insurance, HOA, and total housing cost.

What is PMI?
PMI stands for private mortgage insurance. It is usually required on many conventional mortgages when the down payment is below 20%.
Is 20% down always better?
Not always. A larger down payment may reduce monthly cost and PMI, but it can also reduce cash reserves. Compare both monthly affordability and cash after closing.
Can PMI be removed later?
Often, yes, but the rules depend on the loan, balance, home value, and lender requirements. Review your loan documents and ask the lender for the exact process.
