How is policy loan interest calculated?

The bottom line

How is policy loan interest calculated? Your insurer applies the policy’s stated loan rate to the unpaid loan balance, then adds interest according to the contract’s schedule. A fixed rate stays level; a variable rate can change. Unpaid interest increases the balance and can reduce the policy’s safety margin.

A policy loan is secured by the cash value of permanent life insurance. The amount that accrues interest is the unpaid loan balance, not the policy’s entire death benefit. Your contract controls the rate, when interest is posted, and whether unpaid interest is added to the balance.

Key facts
  • NAIC guidance defines a policy loan as secured by the policy’s cash surrender value.
  • The contract states whether the loan rate is fixed or variable and how the rate is determined.
  • Interest that is added to the loan becomes part of the balance used for later calculations.
  • A large balance can reduce what beneficiaries receive and can put the policy at risk if it exceeds the available value.
  • Tax results depend on what happens to the policy, so a lapse or surrender deserves tax advice.

What is a policy loan?

A policy loan lets the owner of a cash-value life insurance policy borrow under the policy’s terms, using the cash surrender value as security. The National Association of Insurance Commissioners explains that cash-value policies can include whole life, universal life, and variable life coverage, and that loans may be taken against cash value.

The insurer does not send a bank to underwrite the loan in the usual sense. Instead, the policy contract governs the request, the maximum available amount, the interest rate, and repayment terms. The exact rules differ by policy, so a statement or illustration is more reliable than a general rule.

A loan is separate from a withdrawal. With a loan, the insurer records a balance secured by the policy. With a withdrawal, the policy value is taken out under the contract’s withdrawal rules. Ask the insurer which transaction you are requesting before signing a form.

What balance is used to calculate policy loan interest?

Policy loan interest is calculated from the unpaid loan balance identified in the contract. That balance may include the original amount borrowed and any interest that has been added under the policy’s terms. The NAIC’s policy-loan accounting guidance describes the unpaid balance as principal plus certain accrued interest, which illustrates why the current balance matters more than the original advance.

The basic calculation is:

interest for a period = unpaid loan balance × contract rate × time factor

The time factor depends on the policy. A contract may quote an annual rate while posting interest on a stated schedule. Some policies require interest annually. Others use a different schedule. Do not assume that multiplying the balance by the annual rate gives the exact amount due on every date.

How does a fixed or variable loan rate change the calculation?

A fixed loan rate uses the rate stated for the applicable loan period, so the rate itself does not change during that period. A variable loan rate is determined under the contract’s formula and may be reset as the policy specifies. NAIC policy-loan guidance recognizes that policy terms can specify either a fixed rate or a variable rate with a description of how the rate is determined.

That distinction changes the forecast. With a fixed rate, you can model interest by applying one rate to each period’s balance. With a variable rate, you must use each reset rate shown on the insurer’s statement or current illustration. An initially lower rate is not a promise that the total cost will stay lower.

Read the policy pages that describe loan provisions, including the rate basis, any cap or floor, the reset date, and whether the policy offers more than one loan type. If the language is hard to interpret, ask the insurer for a written explanation rather than choosing based on a rate shown in an advertisement.

What happens when interest is added to the loan?

When the contract adds unpaid interest to the loan, the new balance includes that interest. Future interest can then be calculated on the larger balance. This is often called capitalization. It does not mean the policy has a bank-style monthly payment schedule. It means the policy’s recorded debt can grow when charges are not paid.

For an illustration only, assume a $10,000 balance and a 5% annual rate. One year of simple annual interest would be $500 if the rate stayed unchanged and no other charge applied. If the contract posts interest more often or adds unpaid interest during the year, the statement’s amount can differ. The example is not a quote or a prediction of any policy’s rate.

Ask for the insurer’s current loan statement or in-force illustration. It should show the balance, the rate used, the next interest date, and the effect of continuing the loan. Those figures are the practical answer for your policy.

What happens if the loan is not repaid?

An unpaid loan can reduce the death benefit because the insurer may subtract the outstanding loan balance and interest when the policy pays a claim. The policy can also become vulnerable if the loan and other deductions consume the value supporting the contract. NAIC guidance notes that a policy generally lapses when the unpaid balance exceeds the relevant cash surrender value or policy reserves.

That risk is not measured by the original loan amount alone. It depends on the current balance, the rate, future interest, premiums, policy charges, and the contract’s available value. A loan that looked manageable when taken can require attention later, especially if the rate changes or payments stop.

Before borrowing, request an in-force illustration that shows at least one path with the loan unpaid and one path with planned interest payments. Confirm the lapse conditions and grace period in the policy contract.

How can a policy loan affect the death benefit?

The death benefit available to beneficiaries can be lower when a policy loan remains outstanding. The exact adjustment depends on the policy’s loan provision, any credited values, and other deductions. Do not describe the effect as a universal dollar-for-dollar rule without checking the contract.

Cash value and death benefit are related but are not interchangeable. A statement may show a loan balance, net cash surrender value, and death benefit on separate lines. Compare those lines before and after a proposed loan. The NAIC notes that policy loans are taken against cash value, but the policy still determines how values and benefits are credited.

Are policy loans taxable?

A policy loan can have tax consequences if the policy is surrendered or lapses. The IRS says that when a life insurance policy is surrendered for cash, proceeds above the policy’s cost are generally included in income. A loan can affect the amount received and the policy’s cost calculation, so do not treat “not taxable today” as a guarantee that no tax will ever arise.

Tax treatment can depend on the policy, the owner’s basis, prior distributions, and the event that ends the contract. Ask a tax professional to review the numbers before surrendering a policy or allowing a heavily loaned policy to lapse. The insurer can provide the policy values, but it cannot replace individualized tax advice.

What should you check before taking a policy loan?

Before requesting funds, compare the policy’s current loan balance, rate type, rate-reset rule, interest-posting schedule, available value, and projected death benefit. Then ask how much interest would be due at the next statement date and what happens if you pay only interest or make no payment.

  • Locate the loan provision and confirm whether the rate is fixed or variable.
  • Ask for an in-force illustration with the proposed loan amount.
  • Confirm how interest is posted and when it is added to the balance.
  • Check the lapse warning, grace period, and effect on the death benefit.
  • Ask a tax professional about surrender or lapse risk before taking action.

If you want to compare the mechanics before requesting an illustration, the guide to fixed versus variable policy loan rates explains the rate-choice question in more detail. The next step is a policy-specific illustration, not a generic rate estimate.

In short, the contract determines the rate and timing, while the unpaid balance determines the amount exposed to interest. Review those figures with the insurer and keep the policy’s purpose in view before borrowing.

If you are considering a policy loan, you can ask for a personalized illustration from a licensed life insurance agent. It can show the rate, balance, and projected effect on the coverage so you can decide what to review next.
