Free PMI Calculator 2026
Calculate Private Mortgage Insurance (PMI) costs when you put less than 20% down. See how much PMI adds to your monthly payment.
What Is PMI (Private Mortgage Insurance)?
PMI is insurance you pay to protect the lender if you put less than 20% down on a conventional mortgage. It doesn't protect you — it protects the lender if you default.
PMI is required on conventional loans with less than 20% down. It typically costs $30-70 per month per $100,000 borrowed, or 0.5-1.5% of the loan amount annually.
PMI Rates by Credit Score (2026)
Your credit score has a major impact on your PMI rate:
- 760+ credit: 0.35-0.45% annual rate ($29-38/month per $100K loan)
- 740-759 credit: 0.45-0.55% annual ($38-46/month per $100K)
- 700-739 credit: 0.55-0.75% annual ($46-63/month per $100K)
- 660-699 credit: 0.75-1.0% annual ($63-83/month per $100K)
- 620-659 credit: 1.0-1.5% annual ($83-125/month per $100K)
Tip: Raising your credit score from 680 to 740 can cut your PMI in half — saving $50-100/month on a typical loan.
How PMI Affects Your Monthly Payment
On a $400,000 home with 10% down ($360,000 loan):
- Principal & Interest (6.5%, 30yr): $2,275/month
- PMI (0.7% rate, 700 credit): $210/month
- Total: $2,485/month
- PMI increases payment by 9.2%
Over 7 years (typical time to reach 78% LTV), you'll pay ~$17,640 in PMI.
When Does PMI Go Away?
- Automatic cancellation: When loan balance reaches 78% of original home value (based on amortization schedule)
- Request cancellation: When loan balance reaches 80% LTV — you can request early if you've made extra payments or home value increased
- Typical timeline: 5-10 years depending on down payment and extra payments
- With 5% down: Takes ~9 years to reach 78% LTV with normal payments
- With 10% down: Takes ~7 years
- With 15% down: Takes ~4 years
Ways to Avoid PMI
- Put 20% down — The simplest solution. No PMI, lower monthly payment, better rate
- Piggyback loan (80-10-10): 80% first mortgage + 10% HELOC/second + 10% down. Higher total payment but no PMI
- Lender-paid PMI: Lender pays PMI in exchange for 0.25-0.5% higher rate. Cannot be cancelled
- VA loan: 0% down, no PMI. Only for veterans and active military
- USDA loan: 0% down, no PMI (but has a guarantee fee). Only for eligible rural areas
- FHA loan: Has MIP (Mortgage Insurance Premium) instead of PMI. Required for the life of the loan if down payment under 10%
PMI vs Waiting to Save 20% Down
Is it better to pay PMI now or wait until you have 20% down?
- Scenario A — Pay PMI now: Buy $400K home with 10% down. Pay $210/month PMI for 7 years = $17,640 total PMI cost
- Scenario B — Wait 3 years for 20% down: Home appreciates 5%/year = $63K price increase. You saved $17K PMI but paid $63K more for the home. PMI wins by $46K
- Scenario C — Wait 3 years, 2% appreciation: Home costs $24K more. PMI cost $17K. Waiting wins by $7K
Rule of thumb: In a market with 4%+ annual appreciation, paying PMI now is usually cheaper than waiting. In slow markets (under 2% appreciation), waiting may be better.
PMI vs MIP vs Funding Fee
- PMI: Conventional loans, 0.5-1.5%/year, cancellable at 78-80% LTV
- MIP (FHA): 1.75% upfront + 0.55%/year. Required for life of loan if down payment under 10% (or 11 years if 10%+ down)
- VA Funding Fee: 2.15-3.3% upfront (can be rolled into loan). No ongoing mortgage insurance
- USDA Guarantee Fee: 1% upfront + 0.35%/year. Lower than PMI
Frequently Asked Questions
How much is PMI per month?
PMI costs $30-70 per $100,000 borrowed per month (0.5-1.5% annually). On a $320,000 mortgage, expect $133-400/month. Exact rate depends on credit score, down payment, and loan type.
How can I avoid PMI?
Put 20% down or more. Or use a piggyback loan (80-10-10). VA and USDA loans have no PMI. Or accept lender-paid PMI with a higher rate.
When does PMI go away?
PMI automatically cancels at 78% loan-to-value. You can request cancellation at 80% LTV. Typically takes 5-10 years depending on down payment and extra payments.
Is PMI tax deductible?
PMI was deductible through 2025 for AGI under $109,000. The deduction phases out between $100K-109K AGI. Check current tax law as this provision may be extended.
Is it better to pay PMI or wait for 20% down?
Depends on appreciation. If home prices rise 4%+/year, paying PMI now is usually cheaper (the home costs more later). In slow markets under 2% appreciation, waiting may be better. Run the numbers for your market.
