A PMI Calculator is a specialized mortgage tool that computes the monthly cost of Private Mortgage Insurance based on your loan amount, down payment, and the going PMI rate. It also projects the cancellation date by tracking your loan balance against the original home value. Mortgage lenders and financial planners rely on this same method to explain insurance costs and removal timelines.
Many homebuyers are simply told “you’ll pay PMI” without a clear dollar amount or a finish line. That uncertainty can lead to years of unnecessary payments. Even existing homeowners often don’t know they can request PMI cancellation at 80% LTV. This tool removes the guesswork, so you can plan your budget and know when to contact your lender for removal.
Select your currency — Choose from 21 options so the numbers align with your loan.
Enter the home price — Input the original purchase price (the baseline for LTV).
Set your down payment — Use the slider, percentage, or dollar field; the loan amount and LTV update immediately.
Fill in your loan details — Add the interest rate and loan term. This lets the tool compute your monthly P&I.
Specify your PMI rate — Use the typical 0.5%–1.0% range, or check your loan estimate.
Adjust the cancellation LTV if needed — Standard is 78%, but some loans use 80%. Set it to your contract’s rule.
Read your PMI summary — See monthly PMI, total cost, and the exact cancellation date.
The core monthly loan payment uses:M = P × [ r(1 + r)^n ] / [ (1 + r)^n – 1 ]
The loan‑to‑value ratio is LTV = (Loan Amount ÷ Home Price) × 100.
If LTV is above 80%, the monthly PMI is:Monthly PMI = (Loan Amount × PMI Rate / 100) ÷ 12
To find the cancellation date, the tool simulates each month: it subtracts the principal portion of your payment from the balance, recalculates current LTV (Balance ÷ Home Price × 100), and stops PMI when that LTV hits your cancellation threshold. This simulation reflects the standard method used in mortgage servicing.
Example: $250,000 home, 10% down ($25,000), loan = $225,000, rate 6.5%, 30‑year term, PMI rate 0.5%, cancellation at 78% LTV.
Monthly P&I = $1,422.15. LTV = 90%. Monthly PMI = ($225,000 × 0.005) ÷ 12 = $93.75.
The simulation shows the balance drops to 78% LTV after about 81 months, so PMI would cancel near December 2031, with total PMI paid of roughly $7,594.
A buyer is purchasing a $250,000 home with 10% down ($25,000).
Loan: $225,000
Rate: 6.5%
Term: 30 years
PMI rate: 0.5%
Cancellation threshold: 78% LTV
Output:
Monthly P&I: $1,422.15
Monthly PMI: $93.75
PMI required: Yes
Total PMI paid: $7,593.75
PMI cancels on: Dec 2031
That’s over $7,500 that could be saved by either waiting for a 20% down payment or requesting removal earlier if home value rises.

Homebuyers with less than 20% down — See exactly how much PMI adds to the monthly payment.
Existing homeowners — Check when your PMI should automatically terminate.
Mortgage brokers — Illustrate the cost of low‑down‑payment loans to clients.
Real estate agents — Help buyers compare offers with different down payments.
Financial advisors — Use the cancellation timeline when planning debt‑payoff strategies.
FHA loan holders — Although MIP differs, the LTV logic helps understand removal (though FHA rules vary).
Precision down to the month — Know the exact month PMI ends, not a rough “year 7 or 8.”
Custom cancellation threshold — Adjust to your specific lender’s rules (78% or 80%).
Instant scenario comparison — Slide the down payment from 5% to 15% and watch monthly PMI shrink in real time.
Total PMI cost — See the cumulative dollars you’ll spend, making it easier to evaluate a larger down payment.
Global currency support — Use the tool regardless of where you’re buying — 21 currencies available.
Using the original home price instead of a current appraisal — PMI removal by lenders may require a new appraisal; this tool uses the original price as a baseline.
Confusing the 80% and 78% thresholds — Automatic cancellation is at 78%, but you can request cancellation at 80%. Set the threshold accordingly.
Forgetting that PMI rates vary — The default 0.5% is a median; check your loan estimate for the actual rate.
Assuming PMI never cancels — Even if the date looks far, it will end; don’t assume it’s forever.
This calculator tracks PMI based on the original home price only, which is the most common method for automatic cancellation. It does not account for increased property values that could let you cancel sooner via reappraisal. The PMI rate is treated as constant, whereas in reality some loans have step‑down premiums. Finally, FHA loans often have Mortgage Insurance Premiums (MIP) with different rules — this tool is designed for conventional PMI.
Q: How do I know if I have to pay PMI?
A: You likely must pay PMI if your down payment is less than 20% of the home’s purchase price. The calculator shows “PMI Required: Yes” when LTV exceeds 80%. FHA loans always carry mortgage insurance but call it MIP.
Q: What is the difference between PMI and MIP?
A: PMI is for conventional loans; Mortgage Insurance Premium (MIP) applies to FHA loans and has different cancellation rules. This tool models conventional PMI, but the LTV logic is similar for understanding when equity hits thresholds.
Q: How is my monthly PMI calculated?
A: Lenders multiply your loan balance by an annual PMI rate (often 0.5% to 1.5%) and divide by 12. The exact rate depends on your credit score, LTV, and insurer. Enter the rate from your loan estimate into the calculator.
Q: Can I cancel PMI before the automatic cancellation date?
A: Yes. You can request cancellation when your LTV reaches 80% based on the original value, or earlier if improvements or market appreciation raised your home’s value (via a new appraisal). The calculator shows the automatic cancellation date based on original value only.
Q: How does the down payment slider work?
A: The slider adjusts the down payment percentage. As you move it, the percentage field, dollar field, loan amount, and LTV all change simultaneously. You can also type into the percentage or dollar field and the slider will update.
Q: What LTV threshold should I set for PMI cancellation?
A: For automatic cancellation under the Homeowners Protection Act, it’s 78%. For borrower‑requested cancellation, it’s typically 80%. Check your loan documents; the default on the calculator is 78%.
Q: Who commonly models PMI this way?
A: Loan officers, underwriters, and mortgage educators use the same LTV‑driven approach to estimate PMI duration. It’s the standard convention in mortgage origination training.
Q: How do I compare the cost of PMI vs. waiting to save a 20% down payment?
A: The calculator gives you the total PMI you’ll pay. Compare that amount against the extra money you’d need to reach 20% — and factor in whether home prices are rising while you save.
To calculate PMI, first determine your loan‑to‑value ratio: LTV = (Loan Amount ÷ Home Price) × 100. If LTV is above 80%, PMI applies. Then multiply your loan balance by the annual PMI rate (e.g., 0.5%) and divide by 12 to get the monthly cost. Finding the cancellation date requires an amortization schedule — every month you subtract principal, recompute LTV, and stop PMI at 78% (or 80%). It’s that manual complexity that makes this calculator so valuable.
The basic monthly PMI formula is: Monthly PMI = (Loan Balance × Annual PMI Rate) ÷ 12. For cancellation, lenders use: Current LTV = (Current Loan Balance ÷ Original Home Price) × 100. When current LTV first falls to 78% or lower, PMI must be automatically cancelled according to U.S. federal law. These formulas form the backbone of all PMI estimation, including this tool.
Private Mortgage Insurance (PMI) is a policy you pay for but that protects the lender if you stop making payments. It’s required on conventional loans when your down payment is less than 20%, because lenders see lower‑equity loans as riskier. The good news: by law, PMI doesn’t last forever. Once you build enough equity, it cancels automatically. This calculator shows you the cost and that automatic end date.
A frequent mistake is using the annual PMI rate as a monthly number — forgetting to divide by 12 blows up the estimate. Another is thinking PMI is fixed for the whole loan; it actually drops off when LTV hits a threshold, which changes the total cost. People also often forget that FHA loans have different insurance (MIP) that may never cancel. The calculator avoids these errors by correctly applying monthly PMI and simulating the schedule.
PMI (Private Mortgage Insurance) applies to conventional loans and cancels automatically at 78% LTV. MIP (Mortgage Insurance Premium) is for FHA loans; the annual MIP often lasts the life of the loan if you put down less than 10%. When using this calculator for conventional loans, you’re seeing PMI. If you have an FHA loan, the LTV principle is similar but the insurance doesn’t simple cancel — consult an FHA‑specific calculator.
Use it anytime you’re considering a home purchase with less than 20% down. Also run it before requesting PMI removal from your lender — it tells you if you’ve likely hit the 80% or 78% threshold based on original value. If you’re comparing two homes at different price points and down payments, the calculator instantly shows the PMI difference.
Real estate investors using conventional financing on a primary residence or investment property still face PMI if LTV exceeds 80%. The automatic cancellation rules apply the same way, though lenders may require an appraisal. Use this calculator to track when PMI will fall off — freeing up cash flow that can go toward the next property.
