Glossary

PMI

PMI usually means private mortgage insurance, an added cost on some mortgages with lower equity.

Plain-language meaning

Some mortgage calculators include PMI as an optional cost, but rules vary by market and loan type.

Example

A lender may require mortgage insurance when the down payment is below a threshold.

Limitations

PMI is not universal, and country-specific mortgage insurance systems differ.

How this term affects your result

PMI affects the result through the units, time period, rate, threshold or method used by the related calculator. Read it together with the page's formula and assumptions before comparing results across tools or sources.

What to check

  • Use the same unit system, currency and time period as the related calculator.
  • For regulated, health, tax, finance, safety or live-data topics, check the primary source named on the related page.
  • If the term is used as a threshold, rate or category boundary, confirm the exact definition before relying on the estimate.

FAQ

Is PMI defined the same way everywhere?

Not always. Some terms are mathematical and stable, while others vary by country, institution, industry, product or data source.

Why link glossary terms to calculators?

Calculator users often need the term at the moment they interpret a result. Linking the definition to the calculator reduces ambiguity.
