You keep more of your own capital invested while a lender covers the premium checks, and you service the interest (or sometimes roll it into the balance). The policy’s cash value and outside assets back the loan. At death or on exit, the loan gets repaid from the death benefit or cash value, and whatever is left passes on.
Premium finance is a funding tool, not a product. A permanent policy—usually whole life or indexed universal life sized for a real need like estate liquidity or legacy—gets written. Instead of writing a six-figure check every year, a bank or specialty lender advances the premium. You (or more often an irrevocable life insurance trust) own the policy. The lender takes a security interest in the policy’s cash value plus whatever additional collateral is required early on, because a new policy starts with almost no cash value. Interest is typically floating, tied to SOFR plus a spread. You pay that interest out of pocket each year, or in more aggressive designs the interest is capitalized and the loan balance grows. After a set period—often five to ten years—you refinance, repay from policy values, or let the death benefit clear the debt.
Rates matter. When SOFR-based borrowing costs sat near 2.5 percent a few years ago and policy crediting rates ran higher, the math looked cleaner. In 2026 many programs sit closer to 6–7.5 percent all-in. The arbitrage shrinks or disappears unless the policy performs at the upper end of its illustrations and collateral stays solid.
Consider a couple in Texas. He is 52, she is 50. Combined income lands around $480,000—her W-2 from a mid-size software firm plus his consulting practice that throws off the rest. They have a 16-year-old and a 13-year-old. Home equity sits near $900,000. Taxable brokerage is about $1.4 million, mostly index funds and a concentrated position in one of her employer’s old stock grants. Retirement accounts total roughly $1.1 million. They already carry $2 million of term insurance that drops off in a few years. Their estate will likely grow past the current $15 million per-person federal exemption once the business interest and market gains compound, so they are looking at permanent coverage for liquidity and to equalize inheritances.
One path: they buy a $5 million indexed universal life policy with a planned annual premium of $95,000 for seven years. Without financing they write the full $95,000 check each year from taxable accounts or after-tax earnings. Over seven years that is $665,000 of capital they cannot invest elsewhere, plus the opportunity cost of what those dollars might have earned.
With premium finance the lender advances the $95,000 each year. Loan balance after seven years, assuming interest is paid currently and rates average 6.8 percent, sits near $665,000. Their annual cash outlay is the interest—roughly $45,000 in year seven if the balance is fully drawn, less in earlier years. They still have to post outside collateral early on (part of the brokerage account) until the policy’s cash value catches up enough to satisfy the lender’s coverage ratio, often 110–125 percent of the loan. If markets drop hard while the loan is outstanding, a collateral call can force them to add cash or securities at the worst time.
Compare the two. Paying cash keeps the policy unencumbered and eliminates interest-rate and margin-call risk, but it removes $665,000 from their investment portfolio. Financing preserves that capital for the market or the business, yet the net death benefit is reduced by the outstanding loan, interest costs accumulate, and the structure collapses if rates rise further, policy performance lags, or they cannot meet a collateral demand. A second short failure mode shows up when interest is allowed to capitalize: the loan can outrun the cash value, leaving the trust or the couple with a large debt and a policy that no longer pencils.
This does not fit everyone at their income level. Families with thinner liquidity, less predictable earnings, or who simply dislike floating-rate debt and collateral calls should pay cash or buy less coverage. It also fails when the only goal is “cheap permanent insurance” without a clear exit or a genuine need large enough to justify the complexity. Lenders underwrite both the insurance risk and the credit risk; weak balance sheets or concentrated collateral get declined or priced poorly.
What to examine next is straightforward. Run side-by-side illustrations at current SOFR-plus spreads and at rates 150–200 basis points higher. Stress the cash-value growth under the insurer’s guaranteed rates, not just the illustrated non-guaranteed rates. Confirm how much outside collateral will be required in years one through four and what triggers a call. Map the exit: refinance into a policy loan, repay from other assets, or hold to death. And check whether an irrevocable trust ownership keeps the death benefit outside the taxable estate under today’s $15 million individual exemption.
