PMI is the cost of buying with less than 20% down, and buyers tend to either fear it or ignore it. This PMI calculator for agents shows the monthly premium, when it drops off as the loan is paid down, and the total paid along the way. It turns 'should we wait until we have 20%?' into a decision with numbers on both sides.

When does PMI go away?
On conventional loans, borrowers can generally request PMI cancellation when the balance reaches 80% of the home's original value, and it ends automatically at 78% under the Homeowners Protection Act, if payments are current. The calculator estimates when that happens on the original schedule. Extra payments or appreciation can make it sooner.

When to put the PMI Calculator in front of people
When a buyer wants to wait for 20% down
Waiting can make sense, but it has a cost: rent paid and prices that may move. Show the total PMI paid over its lifetime against how long it would take to save the rest. Then the buyer is weighing two real figures.
On listings at entry-level prices
First-time buyers on starter homes are most likely to put down less than 20%. A PMI calculator next to the payment shows them the insurance cost and its end date.
When comparing conventional and FHA
FHA mortgage insurance works differently and can last longer. Run this alongside the FHA loan calculator so buyers see the difference before they talk to a lender.
What your visitor sees
The buyer enters the home price, down payment, rate, term and annual PMI rate. They see when PMI drops off, the monthly PMI, the current loan-to-value, the loan amount, total PMI paid and the monthly principal and interest.
The lead you receive
A buyer deciding how much to put down
The lead shows the Home Price, Down Payment and rate, Monthly PMI, Total PMI Paid and when PMI Drops Off. A buyer looking at this is weighing timing and cash, so they're usually closer to buying than they think.
Follow-up that works
Show what the down payment buys today versus a year from now at their savings rate.
Suggest they ask a lender for PMI quotes, which depend on credit and loan-to-value.
Mention that equity from appreciation may allow earlier removal, subject to the lender's rules.

Say it like this · Call to a buyer who ran PMI
PMI came out around $175 a month and drops off in about eight years on the regular schedule. Saving the full 20% would take you about three more years of rent, so it's worth comparing those two side by side.

Reading the results
What each result means for your follow-up
The same figures your visitor sees arrive in your lead record. Here's how to read the ones that matter.
PMI Drops Off In
When the scheduled balance reaches the loan-to-value at which PMI ends. Extra principal payments or a new appraisal can bring it forward, depending on the lender.
Total PMI Paid
PMI's total cost until it ends. Comparing it with a year or two of rent helps buyers decide whether to buy now or wait.
Current LTV
Loan-to-value at purchase. Above 80% means PMI on a conventional loan. Each 5% of extra down payment usually lowers the PMI rate as well.
What can go wrong
Mistakes that cost agents the lead
Quoting a PMI rate as fact
PMI rates depend on credit score, loan-to-value and the insurer. Present the rate as an assumption, and let lenders quote the actual figure.
Applying PMI rules to FHA
FHA uses its own mortgage insurance premium with different rules and durations. Use the FHA calculator for FHA loans.
Overstating early removal
Removing PMI early based on appreciation depends on lender rules, seasoning and an appraisal. Mention it as a possibility, not a promise.

PMI
Private mortgage insurance, required on conventional loans when the loan-to-value ratio is above 80%, usually because the down payment is under 20%. It protects the lender if you default, not you. This calculator charges the annual PMI rate on the original loan amount and divides it into monthly payments until PMI drops off.
Loan-to-value (LTV)
The loan balance divided by the home’s original value, shown as a percentage. A $288,000 loan on a $320,000 home is 90% LTV. PMI applies above 80% LTV, and its cancellation points are measured against the original value, so LTV falls only as principal is repaid under this calculator’s assumptions.
PMI cancellation at 80%
Under the Homeowners Protection Act, you can ask your servicer to cancel PMI once the balance reaches 80% of the home’s original value, provided you have a good payment history and meet the servicer’s other conditions. Extra principal payments can get you there sooner than the scheduled date this calculator shows.
Automatic PMI termination at 78%
Under the Homeowners Protection Act, PMI ends automatically when the scheduled balance reaches 78% of the home’s original value, if your payments are current, or at the midpoint of the loan term at the latest. The drop-off date this calculator reports is based on the scheduled amortization, without extra payments or reappraisal.
Annual PMI rate
The yearly PMI premium as a percentage of the loan amount. It depends mainly on your credit score and loan-to-value ratio; this calculator’s guidance puts the typical range between 0.2% and 2%. At 0.5% on a $288,000 loan, PMI costs $1,440 a year, or $120 a month.
Down payment
Cash paid toward the purchase price at closing. On a conventional loan, a down payment of less than 20% of the price leaves the loan above 80% LTV and triggers PMI. Every added dollar lowers the loan, the monthly PMI charge and the time until PMI drops off.
Original value
For PMI purposes, the lower of the purchase price or the appraised value at the time the loan was made. The Homeowners Protection Act thresholds are measured against it. Some lenders will also consider a new appraisal showing the home has gained value, but that is a lender policy rather than a legal right.
FHA mortgage insurance (MIP)
The mortgage insurance premium on FHA loans, which works differently from PMI: it has an upfront and an annual premium, and the Homeowners Protection Act cancellation rules do not apply to it. In many cases it lasts for the life of the loan. This calculator models conventional PMI only.
Principal & interest
The part of the monthly payment that repays the loan itself, before PMI, taxes and insurance. It stays the same over a fixed-rate term. As each payment reduces principal, the balance moves toward the 80% and 78% thresholds, which is how this calculator finds the PMI drop-off date.
Calculator disclaimer
Estimates only. PMI applies to conventional loans above 80% loan-to-value. Under the Homeowners Protection Act it ends automatically when your scheduled balance reaches 78% of the original value (or at the loan's midpoint), and you can ask to cancel it at 80%. Rates depend on your credit and loan-to-value — confirm with your lender.
Calculator results are estimates for illustration, not Loan Estimates, pre-approvals or offers of credit.
The annual PMI rate times the loan amount, divided by 12. For example, 0.55% on a $382,500 loan is about $175 a month. The rate depends on credit and loan-to-value, so treat the default as an assumption.
When does PMI end automatically?
Under the Homeowners Protection Act, PMI on most conventional loans ends automatically when the balance reaches 78% of the original value on the original schedule. Borrowers can request removal at 80% if they meet the lender's requirements.
Does the calculator include extra payments?
This calculator uses the original schedule. The mortgage calculator models extra payments, which bring the 80% and 78% points forward.
Should buyers avoid PMI?
Not necessarily. PMI lets buyers purchase sooner with less cash. Whether it's worth it depends on how long saving would take, rent in the meantime and price trends. The calculator shows the PMI side of that comparison.
Can sellers pay a buyer's PMI?
Some programs allow seller-paid or lender-paid mortgage insurance structures, subject to limits. That's a question for the buyer's lender before you include it in an offer.
How do I explain PMI simply?
It's insurance that protects the lender, not the buyer, when the down payment is under 20%. The buyer pays for it, and it usually ends once they have enough equity.
Where does a PMI calculator fit on my site?
On first-time buyer pages, entry-level listings and down payment articles. It works well as a second tab beside the mortgage calculator in a widget.
Can I set a default PMI rate?
Yes. Set a typical rate for your market's credit profile in the calculator settings. Visitors can change it.
Is there a Spanish version?
Yes. The PMI calculator runs in English and Spanish.
