Private mortgage insurance protects your lender, not you — yet you pay for it every month when your down payment is under 20%. The good news: PMI is temporary, and you can often kill it years before the lender is legally required to remove it. This calculator shows all three exit routes and exactly how much each one saves.
PMI Removal Calculator
When does private mortgage insurance fall off — and how much sooner can extra payments or rising home value get rid of it?
Conventional-loan PMI rules under the Homeowners Protection Act: automatic termination at 78% LTV of the original value, borrower-requested cancellation at 80% (with good payment history), and a lender-discretion reappraisal route once current-value equity reaches ~20–25%. FHA mortgage insurance follows different rules. Estimates only — confirm cancellation requirements with your servicer. Not financial advice.
How to use this calculator
Enter the purchase price, your down payment, rate, term and the monthly PMI amount from your loan estimate. Optionally add extra monthly principal and an annual home-appreciation rate. The calculator returns the date PMI auto-terminates, the earlier date you can request cancellation, the appreciation/reappraisal route, and the dollars saved by acting early instead of waiting.
The three ways PMI ends on a conventional loan
The federal Homeowners Protection Act sets the rules for borrower-paid PMI on conventional loans:
- Automatic termination at 78% LTV. Once your loan balance reaches 78% of the original value, the servicer must cancel PMI automatically — provided you are current on payments. This is the legal backstop. It happens on its own, but it is the latest of the three routes.
- Borrower-requested cancellation at 80% LTV. When the balance hits 80% of original value (on the amortization schedule), you can request cancellation in writing, with a good payment history. The lender is generally required to honor it. This is months to years earlier than 78% — but only if you ask.
- The reappraisal / appreciation route. If your home's current market value has risen enough that your equity is roughly 20–25%, many lenders let you cancel PMI early with a new appraisal you pay for. In hot markets this is often the fastest route of all.
Why "request" is the key word
Routes 1 is automatic. Routes 2 and 3 are not — the lender will happily keep collecting PMI until 78% if you never act. Most borrowers leave money on the table simply because nobody told them they could request cancellation at 80%, or get an appraisal once their home appreciated. On a $400,000 home with $150/month PMI, the gap between "requested early" and "waited for automatic" is frequently $3,000–$6,000.
How extra principal accelerates removal
Every extra dollar of principal moves you toward the 80% and 78% thresholds faster. Because PMI is a fixed monthly cost, shaving even a year off the timeline is pure savings — and unlike interest savings, it is immediate and certain. The calculator shows the exact months and dollars your extra payment removes.
Appreciation can beat payments entirely
In a market rising 4–5% a year, your equity can hit 20% of current value long before your loan balance reaches 80% of the original price. That is why the reappraisal route is powerful: you are not waiting to pay the loan down — the market is doing it for you. The cost is one appraisal (typically $400–$600); the payoff is canceling PMI months or years sooner.
Frequently asked questions
Is PMI the same as FHA mortgage insurance? No. This calculator covers conventional-loan PMI under the Homeowners Protection Act. FHA loans carry MIP, which often lasts the life of the loan and follows entirely different cancellation rules.
Does PMI really cancel automatically? Yes, at 78% LTV of the original value, if you are current on payments. But that is the latest exit. Requesting at 80% or via appreciation is usually earlier and is on you to initiate.
What is the difference between 80% and 78%? 80% is when you can request cancellation (you must ask, with good payment history). 78% is when the lender must cancel automatically. The 78% point comes later on the schedule.
Can home appreciation remove PMI? Often yes. If a new appraisal shows your equity is about 20–25% of current value, many lenders allow cancellation. Requirements vary — newer loans sometimes need 25% equity; ask your servicer for its exact threshold and seasoning period.
Do extra payments really speed this up? Significantly. Extra principal reaches both the 80% and 78% thresholds sooner, removing fixed PMI payments earlier. The calculator quantifies the months and dollars.
Who pays for the appraisal? You do, typically $400–$600. It is almost always worth it if it cancels even six months of PMI early — the calculator shows your specific PMI savings to compare.
Will refinancing remove PMI? It can, if the new loan's LTV is at or below 80% of current value. But refinancing has its own closing costs and resets the term — usually only worth it if the rate also improves. Compare with a refinance break-even calculation first.
What if I am not current on payments? Automatic termination can be delayed until you are current. Keep payments on time; a clean history is also required for an 80% borrower request.
Methodology
The loan is amortized monthly at the entered rate. The 80% and 78% thresholds are tested against the original purchase value (per the Homeowners Protection Act). The appreciation route grows the home value monthly and tests when the balance falls to 80% of the current value. PMI saved compares total PMI paid to automatic 78% termination with no extra payments against the earliest realistic cancellation (80% request or appreciation route, with any extra principal). Conventional loans only; FHA differs. Estimates for planning and education — confirm exact requirements with your servicer. Not financial advice.
