Worked example

Purchase Price
$300,000
Down Payment
$30,000 (10% LTV 90%)
Loan Amount
$270,000
Credit Score
720
Annual PMI

How it works

Annual PMI Premium = Loan Amount × PMI Rate (varies by credit score). Monthly PMI = Annual Premium / 12. PMI rates: 620-639 credit score (1.50%), 640-659 (1.31%), 660-679 (1.23%), 680-699 (0.98%), 700-719 (0.79%), 740-759 (0.58%), 760+ (0.46%) as percentage of original loan amount.
