If your down payment was less than 20% of the home’s price, there’s a good chance a line labeled “PMI” is quietly sitting on your mortgage statement every month. It’s not a fee lenders invented to pad their profits — it’s insurance that protects the lender, not you, in case you default. But it still comes out of your pocket, and it can add hundreds of dollars a month to your payment for years if you don’t track when it’s supposed to disappear.
This guide explains exactly how PMI is calculated, how it shows up in your monthly payment, and the specific milestones that make it drop off — some automatic, some you have to request yourself.
What PMI Actually Is
Private Mortgage Insurance (PMI) applies to conventional loans (not FHA or VA loans, which have their own insurance rules) when your down payment is under 20% of the purchase price. Lenders see a smaller down payment as higher risk, so they require PMI to cover their potential loss if you stop paying.
PMI is not one flat number — it’s a percentage of your loan amount, charged annually but usually collected monthly as part of your regular mortgage payment.
How PMI Is Calculated
Most PMI premiums fall between 0.3% and 1.5% of the original loan amount per year, depending on:
- Your credit score
- Your loan-to-value ratio (LTV) — how much you borrowed versus the home’s value
- The loan term
- Whether it’s a fixed or adjustable-rate mortgage
A Worked Example
Say you buy a home for $400,000 with a 10% down payment, so your loan amount is $360,000.
At a 0.75% annual PMI rate:
- Annual PMI cost: $360,000 × 0.75% = $2,700/year
- Monthly addition to your payment: $2,700 ÷ 12 = $225/month
That $225 is added on top of your principal, interest, taxes, and homeowner’s insurance — often shown as a single bundled figure on your statement (sometimes called PITI + PMI).
To see how this changes your total monthly outgo alongside principal and interest, run your loan amount and rate through our EMI Calculator — it’s a quick way to separate what’s actually loan repayment versus what’s insurance overhead.
Why PMI Rate Isn’t Fixed for Everyone
Two buyers with identical loan amounts can pay very different PMI premiums. A borrower with a 760 credit score and a 12% down payment might pay close to the low end (around 0.3–0.4%), while a borrower with a 620 score and a 5% down payment could be quoted closer to 1.2–1.5%. This is one more reason it’s worth improving your credit score before applying, not just for the interest rate but for the PMI rate too.
When Does PMI Drop Off?
This is the part most homeowners don’t track closely enough — and it can cost them thousands in unnecessary premiums. There are three ways PMI can go away:
1. Automatic Termination at 78% LTV
Under the U.S. Homeowners Protection Act, your lender is required to automatically cancel PMI once your loan balance reaches 78% of the home’s original purchase price — as long as you’re current on payments. This happens based on your amortization schedule, not the home’s current market value.
2. Borrower-Requested Cancellation at 80% LTV
You don’t have to wait for the automatic cutoff. Once your loan balance reaches 80% of the original value, you can formally request PMI cancellation in writing. Some lenders may require a good payment history and, occasionally, a new appraisal to confirm the home hasn’t lost value.
3. Early Cancellation Through Extra Payments or Appreciation
If you make extra principal payments, you can reach the 80% (or 78%) threshold years earlier than the standard schedule. Similarly, if your home’s market value has risen significantly, you may be able to request cancellation based on a new appraisal, even if you haven’t paid down the original loan balance to 80% — though this route often involves an appraisal fee and stricter lender rules.
Our guide on reading an amortization schedule like a lender does breaks down how principal and interest split changes over time — useful for spotting exactly when your balance is projected to cross the 80% and 78% marks.
How to Track Your PMI Removal Date
- Find your original loan amount and PMI disclosure — it states the LTV thresholds and estimated cancellation date.
- Check your amortization schedule for the month your balance is projected to hit 80% of the original purchase price.
- Track extra payments separately — if you’re paying down principal faster than scheduled, recalculate your revised cancellation month.
- Mark a calendar reminder a few months before the projected date to request cancellation in writing rather than waiting for the lender’s automatic 78% trigger.
If you want to see how extra monthly principal payments shift your payoff timeline — and by extension, your PMI removal date — the Loan Calculator lets you model different repayment scenarios side by side.
PMI vs. MIP (FHA Loans)
It’s worth noting that FHA loans use MIP (Mortgage Insurance Premium) instead of PMI, and the rules are stricter — on many FHA loans originated after 2013, MIP stays for the life of the loan regardless of your LTV, unless you refinance into a conventional loan. If you’re comparing an FHA loan against a conventional one, this difference alone can be significant over a 30-year term.
Bottom Line
PMI isn’t a permanent cost — it’s designed to disappear once you’ve built enough equity, but the timeline depends on your original agreement, your payment behavior, and how proactive you are about tracking your loan-to-value ratio. Reviewing your amortization schedule every year (or after any extra payment) is the simplest way to make sure you’re not paying for insurance you no longer legally need.
