How Much Does PMI Cost?
Editorial Team · Updated July 1, 2026
Private mortgage insurance (PMI) usually costs between 0.46% and 1.5% of your loan amount per year — about $30 to $70 a month for every $100,000 you borrow. On a $300,000 loan that is roughly $115 to $375 a month, added to your payment until you build enough equity.
You pay PMI on a conventional loan whenever your down payment is under 20%. Your exact rate is driven mostly by your credit score and how much you put down: a strong score and a larger down payment push it toward the low end, a lower score toward the high end.
