What Is PMI?

Private Mortgage Insurance protects the lender when your down payment is under 20%, which is why most lenders require it. The cost is typically 0.3–1.5% of the loan amount per year, added to your monthly payment.

PMI does not last forever — it is usually removed automatically once your equity reaches 22% (or at your request at 20%). The calculator shows the monthly and annual cost, and the equity milestones.

The Method

Annual PMI = loan amount × PMI rate
Monthly PMI = annual ÷ 12

The PMI rate you enter is the key assumption — it varies with credit score, loan type and down payment. 0.5% is a common low-end figure; 1%+ applies with smaller down payments.

Frequently Asked Questions

How much is PMI?

Typically 0.3–1.5% of the loan amount per year, depending on down payment and credit. On a $300k loan at 0.5%, that is $125/month.

How do I avoid PMI?

Put down 20%, use a piggyback loan, or choose a lender-paid option (often with a slightly higher rate).

When does PMI end?

Lenders must cancel it automatically at 22% equity; you can usually request cancellation at 20% based on current value.

Is PMI tax-deductible?

Treatment has changed over the years and by jurisdiction — check current rules for your situation.

Do all loans require PMI?

No — VA loans and some programs do not; FHA loans use a similar mortgage insurance premium instead.
