When you put less than 20% down on a home, lenders require private mortgage insurance (PMI) to protect themselves if you default. Most people think of PMI as a small monthly line on their mortgage statement, but there is another way to pay for it: upfront PMI (also called single-premium PMI, prepaid PMI, or lender-paid PMI). Instead of adding roughly $100–$200 to every monthly payment, you pay the entire insurance premium once, at closing. This calculator sizes that one-time fee and compares it against the monthly alternative so you can see exactly how long you would have to stay in the home before the upfront choice actually pays off.
Enter your loan amount, the upfront PMI rate your lender quoted, and the annual rate you would pay in monthly PMI. The result card shows the lump-sum fee, the equivalent monthly cost, your break-even point, and what happens if you roll the upfront fee into the loan instead of paying it out of pocket.
How to Use
- Enter the Loan Amount — the mortgage principal after your down payment. Use the balance on your loan estimate; do not include closing costs yet.
- Set the Upfront PMI Rate your lender quoted, as a percent of the loan. Conventional single-premium PMI usually runs 0.5%–3.5% of the loan amount, depending on your credit score and down payment.
- Enter the Monthly PMI Rate (annual) your lender would charge if you paid PMI the normal way — typically 0.3%–1.5% of the loan balance per year. This is the figure the calculator uses for the side-by-side comparison.
- Type your Interest Rate (APR). It only affects the "if financed" lines, which show what rolling the fee into the mortgage really costs after interest.
- Choose the Loan Term — 30 years is standard, but a 15-year loan changes how long the financed fee is amortized.
The result card first shows your Upfront PMI (One-Time) fee — the cash you would hand over at closing. It then converts the monthly alternative into Monthly PMI Comparison, divides the one-time fee by that monthly amount to give your Break-Even in months and years, and finally shows how much the fee grows if you finance it into principal.
How Upfront PMI Is Calculated
The math is deliberately simple, because the premium is a percentage of the loan rather than an annualized charge:
- Upfront PMI cost = loan amount × upfront PMI rate ÷ 100
For example, on a $300,000 loan with a 1.0% upfront premium, the one-time fee is $300,000 × 1.0% = $3,000. That entire $3,000 is paid at closing, and (under a single-premium structure) your monthly PMI line then drops to $0.
By contrast, the monthly route at 0.5% per year on the same $300,000 loan costs $300,000 × 0.5% ÷ 12 = $125 per month. The break-even point is therefore $3,000 ÷ $125 = 24 months — about 2 years. If you sell or refinance within two years, paying monthly was cheaper; if you stay longer than two years, the upfront fee wins.
Paying Out of Pocket vs. Financing the Fee
You generally have two ways to handle the upfront premium:
- Pay out of pocket at closing. The fee leaves your bank account on closing day but is not financed, so it never accrues interest. Your loan balance stays exactly $300,000.
- Finance it into the loan. The $3,000 is rolled into principal, raising your loan to $303,000. You avoid bringing extra cash to closing, but you now pay interest on that $3,000 for the full loan term. On a 30-year loan at 6.5%, a $3,000 financed fee adds roughly $19 to your monthly payment and grows to about $6,826 in total outlay — more than double the original fee once interest is included.
A third structure, lender-paid PMI (LPMI), works differently: the lender pays the premium up front in exchange for a slightly higher interest rate. That is a rate-buydown decision, best modeled on a mortgage-points calculator rather than this one.
Examples
Example 1 — The classic comparison. A buyer takes a $300,000 loan, quotes a 1.0% upfront premium and a 0.5%/yr monthly alternative at a 6.5% rate for 30 years. The upfront fee is $3,000, the monthly alternative is $125, and break-even is 24 months (2.0 years). Staying in the home beyond two years makes the prepaid choice cheaper; selling sooner favors monthly PMI.
Example 2 — A jumbo loan. On a $1,000,000 loan with a 1.5% upfront rate and 0.7%/yr monthly PMI at 7.0% for 30 years, the one-time fee jumps to $15,000, while the monthly alternative is about $583. Break-even lands near 26 months (2.14 years). The financed option adds roughly $100/month and costs about $35,926 over the full term — a sharp reminder that rolling a large premium into a high-balance loan is expensive.
Example 3 — A zero-premium quote. If a lender quotes 0% upfront PMI, the one-time fee is $0, break-even is 0 months, and the calculator simply reports the ongoing $83/month cost on a $200,000 loan. This is the same as choosing the monthly-only structure, and it keeps your closing costs as low as possible.
FAQ
What is upfront PMI?
Upfront PMI (also called single-premium or prepaid private mortgage insurance) is a one-time lump-sum payment at closing that replaces the recurring monthly PMI premium. It is calculated as a percentage of the loan amount — for example, 1.0% of a $300,000 loan is a $3,000 fee. After paying it, your monthly PMI line usually drops to zero.
Is upfront PMI better than monthly PMI?
It depends on how long you keep the loan. If you stay in the home past the break-even point — typically around 2–4 years based on the rates above — the one-time fee costs less than the cumulative monthly premiums. If you expect to move, refinance, or reach 20% equity quickly, paying monthly is usually cheaper. Use the break-even result on this page to decide.
Can I roll upfront PMI into my loan?
Yes. Many lenders let you finance the premium into the loan balance so you bring less cash to closing. The trade-off is that you then pay interest on the fee for the entire loan term. On a 30-year loan, a financed $3,000 premium can grow to roughly $6,800 in total cost at a 6.5% rate.
What is the difference between upfront PMI and lender-paid PMI?
Upfront (single-premium) PMI is paid by you, either out of pocket or financed into the loan. Lender-paid PMI (LPMI) is paid by the lender, but in return you receive a slightly higher interest rate for the life of the loan. LPMI is effectively a permanent rate increase, while single-premium PMI is a fixed closing cost with no ongoing interest if paid out of pocket.
How much does upfront PMI cost?
Typical single-premium PMI runs 0.5%–3.5% of the loan amount, with the exact rate set by your credit score, down payment, and loan program. On a $300,000 loan that range is $1,500–$10,500. Enter your own quote in the Upfront PMI Rate field above for an exact figure.
Does upfront PMI go away over time?
Because it is a single prepaid premium, there is nothing to cancel later — unlike monthly PMI, which federal law requires lenders to drop once you reach 78% loan-to-value. The trade-off is that you generally do not receive a refund if you refinance or sell early, which is why the break-even comparison matters.
