How it works
Private mortgage insurance is the premium a borrower pays to protect the lender — not themselves — when a conventional loan starts above 80% loan-to-value, typically $40 to $250 per month per $100,000 borrowed. It is also one of the few insurance products you can legally fire early, which makes knowing your removal date pure money. Federal law fixes three doors: you may request cancellation once the balance reaches 80% of the ORIGINAL price; servicers must terminate automatically at 78%; and if the home's VALUE has risen enough that your balance sits under 80% of today's worth, most lenders will remove PMI after a reappraisal costing $150–$500. This calculator walks your amortization month by month under all three routes, flags whichever arrives first, totals the premiums still payable until then, and shows the annual savings waiting on the other side. On the defaults — a $378,000 loan at 6.5% with the home now worth $450,000 — appreciation alone pulls the reappraisal door open years before scheduled amortization would, sparing roughly $185 every month indefinitely. Extra principal accelerates every route at once. FHA borrowers face different rules: most post-2013 FHA mortgages carry mortgage-insurance premiums for life regardless of equity, so escape usually means refinancing to conventional.Formula
Cancel at balance ≤ 80% × original price | Auto-end at ≤ 78% | Reappraisal route at ≤ 80% × today's value
Tips
- Request removal in writing the moment you cross any threshold — nobody does it for you early.
- A $300 reappraisal beats years of $185 premiums whenever values have risen.
- Direct the freed PMI dollars to principal to compound the win monthly.
- FHA MIP mostly lasts the life of the loan — plan a conventional refi instead.
- Re-run this after each annual appraisal notice; values move the date more than payments do.
