PMI Explained: When It Drops Off and How to Avoid It
Private mortgage insurance (PMI) is one of the more confusing line items on a mortgage statement, mostly because it's insurance that protects your lender, not you — yet you're the one paying for it.
Why it exists
PMI is typically required on conventional loans when your down payment is less than 20% of the home's price. Statistically, loans with smaller down payments default more often, so lenders require PMI as protection against that added risk. It has nothing to do with protecting your health, your income, or your ability to make payments — it exists purely to protect the lender if you default.
How much it typically costs
PMI usually runs somewhere between 0.3% and 1.5% of the original loan amount per year, split into your monthly payment. The exact rate depends on your credit score, loan-to-value ratio, and loan type — a lower credit score or a smaller down payment generally means a higher PMI rate.
When it automatically goes away
Under federal law (the Homeowners Protection Act), your lender must automatically cancel PMI once your loan balance reaches 78% of the home's original value, as long as you're current on payments. You can also request cancellation earlier — once you hit 80% loan-to-value — though this usually requires a request in writing and sometimes a new appraisal to confirm the value.

If you're close to that threshold, paying a lump sum toward principal can get you there sooner — but whether it's actually worth it depends on the numbers. Our PMI removal calculator runs the real math on your specific loan, including the cases where waiting is the smarter financial move.
How to avoid PMI in the first place
- Put down 20% or more. The most direct way — no PMI is charged at all if your down payment clears the 20% threshold.
- Piggyback loans. Some buyers use a second loan to cover part of the down payment, avoiding PMI on the primary loan — though this comes with its own costs and risks worth comparing carefully.
- Lender-paid PMI. Some lenders offer to cover PMI in exchange for a slightly higher interest rate for the life of the loan. This can be cheaper short-term but often costs more over a long hold, since the rate increase never goes away the way standard PMI does.
Is paying PMI ever the right call?
Yes — if waiting to save a full 20% down payment means waiting years while home prices and rates rise, paying PMI temporarily to buy sooner can still work out ahead financially, especially since it's a temporary cost that disappears once you cross the equity threshold. The key is knowing your PMI removal date and requesting cancellation as soon as you're eligible, rather than assuming your lender will proactively flag it early.
