PMI Calculator: When You Need It and When to Drop It

You are buying your first home. You have $30,000 saved. The home costs $400,000. That is only 7.5% down, not 20%. The lender says you need private mortgage insurance (PMI). The cost is $250 per month. You are frustrated. You already stretched to save $30,000. Now you have to pay an extra $250 every month for something that protects the lender, not you.

Here is the truth. PMI is not a punishment. It is a risk-based fee. Lenders charge PMI when you put down less than 20% because statistics show that borrowers with less equity are more likely to default. But PMI is not permanent. You can cancel it once you reach 20% equity. And you can reach 20% equity faster than you think through a combination of principal payments and home appreciation.

Most online PMI calculators are attached to lead generation forms. Bankrate will ask for your email before showing you PMI estimates. NerdWallet buries the PMI information behind a "get personalized rates" button. LendingTree does not even have a standalone PMI calculator — they just want you to apply for a loan. Truly Free Mortgage Calculator includes a PMI calculator that tells you exactly how much you will pay and exactly when you can cancel. No email. No phone call.

How PMI Works (With Real Numbers)

Let me explain PMI with a concrete example. You buy a $400,000 home with 5% down ($20,000). Your loan amount is $380,000. PMI rates vary based on credit score and down payment. For a borrower with a 720 credit score and 5% down, PMI is typically 0.8% of the loan amount annually. That is $3,040 per year, or $253 per month. That monthly cost is added to your mortgage payment.

Now, when can you cancel PMI? Two ways. First, when your loan-to-value (LTV) ratio reaches 80%. That means your outstanding loan balance is 80% or less of the home's current value. For a $400,000 home, 80% LTV is a $320,000 loan balance. You started at $380,000. You need to pay down $60,000 in principal. How long does that take? On a 30-year loan at 6.8%, your monthly principal payment in the first year is about $250. It increases slowly. It would take about 11 years to pay down $60,000 through scheduled payments alone. But your home might also appreciate.

Second, you can request PMI cancellation when you reach 80% LTV based on the original value. By federal law — the Homeowners Protection Act, summarized in the CFPB's guide to private mortgage insurance — your servicer must automatically terminate PMI when you reach 78% LTV based on the original amortization schedule. That happens around year 11 as well. But if your home appreciates, you can get an appraisal and request cancellation earlier. If your $400,000 home appreciates to $450,000 in 3 years, your loan balance is about $365,000. LTV = 365,000 / 450,000 = 81%. That is close. An appraisal might get you there.

The key takeaway: PMI is temporary. On a $380,000 loan at 0.8%, total PMI paid over 11 years is about $33,400. That is a real cost. But if waiting to save 20% down would take you 3 more years, during which home prices might rise 10%, you could be worse off. The math is not simple.

Step-by-Step: Calculate Your PMI and Cancellation Date

Here is how to use the Truly Free Mortgage PMI calculator.

1. Go to trulyfreemortgage.com/mortgage-calculator
That is the free calculator. No account, no email.
2. Enter your home purchase price
Use the actual price you paid or are considering. Example: $400,000.
3. Enter your down payment amount
Type a dollar amount or drag the slider — the percentage updates automatically. For 5% down on $400,000, that is $20,000, and the calculator shows your loan amount ($380,000).
4. Turn on the PMI toggle under "Additional Costs"
The calculator applies a flat, national-average PMI rate (about 0.8% of your loan amount per year) rather than a credit-score-based tier — it does not ask for or use your credit score.
5. Enter your interest rate
Use your own lender quote or a current market rate. This is needed to calculate how fast you pay down principal.
6. Open "Full Amortization Schedule" to see your balance drop over time
The calculator does not project home appreciation or compute a PMI cancellation date automatically. Compare the declining loan balance in the schedule against your own estimate of current home value to see roughly when you would cross 20% equity.
7. Watch your total monthly payment update live
There is no separate "Calculate" step — PMI and every other cost recalculates instantly in your browser as you change an input.
8. Change the down payment to test other scenarios
Raise it to 10% ($40,000 on a $400,000 home) and watch the PMI line and total monthly payment update immediately, since the loan amount and PMI base both shrink.

The Lead-Gen Problem With Free Mortgage Calculators

Bankrate's PMI content is actually a lead generation funnel for its "Mortgage Insurance" partners. They have articles about PMI, but the calculators are minimal. To get a personalized PMI quote, you must enter your email and phone number. That information is sold to mortgage insurance companies who will call you to sell you their product. You do not need mortgage insurance — your lender will arrange PMI through their own channels.

NerdWallet's PMI calculator is more honest. They show estimates without requiring an email. But they still have a large button: "Compare PMI Rates." That button leads to a form that asks for your contact information. NerdWallet earns a referral fee when you purchase a loan through their partners. They are not evil, but they are not neutral.

LendingTree does not even pretend. Their "PMI" page is just a lead form titled "Get Matched with Lenders." There is no calculator. You fill out the form, and they auction your information to multiple lenders. Your phone will ring within minutes.

Truly Free Mortgage Calculator gives you PMI estimates without any lead capture. I do not have a "compare rates" button. I do not partner with lenders. I do not sell your information. The calculator uses standard PMI tables from Freddie Mac and Fannie Mae. It is accurate enough for planning. When you actually apply for a loan, your lender will give you a precise PMI quote. But for deciding how much down payment to save, my calculator is all you need.

Frequently Asked Questions

How much PMI will I pay on a $300,000 loan with 5% down and a 740 credit score?
For a 740 credit score, PMI rate is about 0.6% annually. $300,000 × 0.6% = $1,800 per year, or $150 per month. With 10% down, the rate drops to about 0.4%, or $1,200 per year ($100 per month). With 15% down, PMI could be as low as 0.2%, or $600 per year ($50 per month).
Can I cancel PMI without refinancing?
Yes, if you have a conventional loan. The Homeowners Protection Act requires lenders to cancel PMI automatically when your LTV reaches 78% based on the original amortization schedule. You can also request cancellation when you reach 80% LTV based on current value. You will need an appraisal (cost $400-$700) to prove the current value. FHA loans have different rules (MIP for the life of the loan if you put less than 10% down).
How much home appreciation do I need to cancel PMI early?
Formula: (Loan balance / Home value) ≤ 0.80. If your loan balance is $360,000, you need a home value of at least $450,000. That is $50,000 appreciation from a $400,000 purchase. On a $400,000 home, 12.5% appreciation. In a hot market, that could take 2-3 years. In a slow market, 5-7 years.
Is PMI tax-deductible in 2026?
No. The deduction for PMI expired at the end of 2021 and has not been renewed. For loans originated after 2021, PMI is not deductible. Some lawmakers have proposed reinstating it, but as of mid-2026, it is not deductible.
Should I put 20% down to avoid PMI or put less and invest the difference?
This depends on your investment returns. If you have $80,000 for a 20% down payment on a $400,000 home, you avoid PMI of about $250/month. That is a guaranteed 3.75% annual return on the extra $40,000 you would have put down (compared to 10% down). If you think you can earn more than 3.75% investing that $40,000, then put 10% down and invest. But PMI adds risk. Most financial advisors recommend avoiding PMI if you can.
Does my PMI payment go down over time as my loan balance decreases?
For conventional loans, the PMI premium is typically a fixed dollar amount each month. It does not decrease automatically. But when you refinance or cancel PMI, it stops entirely. FHA MIP does decrease slightly over time because it is calculated as a percentage of the remaining balance.

Calculate your PMI now. See exactly how much that 5% vs 10% vs 20% down payment costs you in monthly PMI. Then decide how much to save before buying.
