Mortgage Definition
PMI (Private Mortgage Insurance)
Insurance required by lenders when your down payment is less than 20%. PMI protects the lender if you default. It adds to your monthly payment but can be removed once you reach 20% equity.
Also called private mortgage insurance or, in some search queries, simply mortgage insurance (for conventional loans). Your PMI cost is usually tied to your loan-to-value ratio, so the LTV Calculator helps you model the same scenario more accurately.
Why it matters
PMI can materially change monthly payment comfort when your down payment is below 20%. Modeling PMI early helps avoid budget surprises and sets a realistic timeline for removal.
How Private Mortgage Insurance (PMI) affects your monthly payment
PMI adds a monthly charge when your down payment is below 20% on many conventional loans. Even when the base mortgage payment looks affordable, PMI can change your comfort range once taxes and insurance are included.
- Example: a $350,000 loan with 0.8% annual PMI adds about $233/month before taxes and homeowners insurance.
- Typical PMI ranges vary by loan type, credit profile, and LTV, so run a low/base/high estimate instead of assuming one number.
- That is why buyers often search both “PMI” and “mortgage insurance” when comparing payment scenarios.
Run the numbers in the Mortgage Calculator, check your loan-to-value with the LTV Calculator, compare with your budget in the Affordability Calculator, and use the Down Payment planner to test how quickly you can reduce PMI exposure.
When PMI can be removed
PMI removal rules depend on loan type, payment history, and equity. For many conventional loans, borrowers may request removal once they reach the required equity threshold and meet lender conditions. Review your loan documents and servicer rules before assuming PMI will drop on a specific date.
- Keep records of your original home value, recent balance, and payment history.
- Ask your servicer what documentation is required for PMI removal (and whether an appraisal is needed).
- If you are close to the threshold, compare the cost of waiting versus making extra principal payments.
- Re-check monthly affordability after PMI drops because escrow items (taxes/insurance) can still change.
PMI removal improves monthly cash flow, but it does not reduce your cash-to-close for the initial purchase. Plan both together.
PMI vs. mortgage insurance on FHA loans (MIP)
Buyers often use “PMI” as shorthand for any mortgage insurance, but FHA loans usually use mortgage insurance premium (MIP) rules instead. The pricing and removal rules can differ from conventional PMI, so compare quotes carefully before choosing a loan type.
A good workflow is: compare monthly payment in the Mortgage Calculator, confirm budget in the Affordability Calculator, then test your down-payment timeline in Down Payment Boss Fight.
