Using Life Insurance to Build Wealth: What Cash Value Can and Can’t Do

You may have seen the pitch. Buy a permanent life insurance policy and watch it grow tax-deferred. Borrow against it when you need cash. Leave a death benefit to your family. Some sellers make it sound like a secret that rich people use and everyone else misses.

There is real substance behind parts of that story. There’s also a lot of marketing. This guide walks through how cash value policies work and when they might make sense. It also covers the risks that rarely make it into the brochure.

In This Guide

First the basics

Term life insurance pays a death benefit if you die during a set period. It has no cash value. Permanent life insurance lasts your whole life as long as you keep paying. Part of each premium goes into a cash value account that grows over time.

That cash value is what people mean when they talk about building wealth with life insurance. The question is whether the growth and the cost make sense for your situation.

The main types of cash value policies

Whole life: fixed premiums and a guaranteed cash value growth schedule and sometimes dividends from the insurer
Universal life: flexible premiums and a death benefit you can adjust and interest credited to the cash value
Indexed universal life: cash value growth linked to a market index with caps and floors
Variable universal life: cash value invested in sub-accounts that rise and fall with the market

Each one trades off guarantees and flexibility and risk differently. Dividends from mutual insurers are not guaranteed. Indexed products limit your upside through caps. Variable products can lose value.

What people like about cash value

The appeal is real for some buyers.

Cash value grows tax-deferred while it stays in the policy
You may be able to borrow against it without selling investments
The death benefit usually passes to beneficiaries income tax free
Whole life offers predictable guarantees that some people value

Those features can help people who have already maxed out other tax-advantaged accounts. They can also help business owners and people planning an estate.

What the brochures skip

Here’s where honesty matters.

Costs are high early on. Commissions and fees mean that in the first years the cash value may be far lower than the premiums you’ve paid. Many policies have surrender charges. If you cancel early you can lose a big chunk.

It takes decades. These policies are built for long holding periods. If you can’t keep paying for many years then another approach is likely better.

Loans reduce your benefit. Borrowing against cash value lowers the death benefit if you don’t repay. Interest accrues. If loans grow too large the policy can lapse and that can trigger a tax bill.

Returns aren’t magic. Cash value growth is often modest compared with simply investing in a diversified portfolio. Cost matters a lot over time.

The MEC trap

Tax law puts limits on how much money you can pour into a policy in the early years. If you go over the limit the policy becomes a modified endowment contract known as a MEC. That changes how withdrawals and loans are taxed and can remove the tax advantages that made the strategy appealing.

You can read how the tax rules treat life insurance in resources from the Internal Revenue Service. If you plan to overfund a policy ask your agent to confirm in writing how the policy stays clear of MEC status.

The compare it honestly test

Before you buy a permanent policy as an investment compare it with the alternatives. Ask yourself a few questions.

Step 1: Have I used my employer retirement plan match and my other tax-advantaged accounts first.

Step 2: Do I truly need permanent coverage for life or only for a set period.

Step 3: Could I buy term insurance and invest the difference in a low-cost account.

Step 4: Can I afford the premiums for the next twenty or thirty years without strain.

For a lot of people the answer to the third question favors term plus investing. For some people the guarantees and estate features of permanent coverage are worth the cost. The point is to decide with the numbers in front of you.

Ask for the illustration and read it

Any permanent policy comes with an illustration. It shows projected values under assumptions. Pay attention to the guaranteed column and not only the projected column. The projected numbers depend on dividend or interest assumptions that may not come true.

Ask the agent how much of your first-year premium goes to costs. Ask what the surrender charge schedule looks like. Ask what happens to the policy if you reduce or skip premiums. And ask what the policy looks like if returns come in at the lower end.

Be careful with big promises

Some marketing uses phrases like infinite banking or tax-free retirement. Those are sales terms and not official product categories. Strategies built around heavy borrowing carry risk. If something sounds too good to be true then slow down.

Variable policies are securities and the Financial Industry Regulatory Authority offers investor education on them. For general regulatory help you can also visit the National Association of Insurance Commissioners.

Who might benefit

Permanent coverage can fit in a few situations.

People with a lifelong dependent who will always need financial support
Business owners planning succession
People with larger estates who want liquidity to pay taxes
Savers who have already maxed other accounts and want guarantees

It’s less likely to be the best first move for someone just starting to save or someone on a tight budget.

If you only need protection

Many families need a large amount of coverage for a limited time. That’s where term shines. Our guide to how much life insurance you actually need shows how to size a policy. And our article on the best life insurance in 2026 explains how to compare companies.

Questions to ask before you sign

How much of my first year premium goes to commissions and fees
What does the surrender charge schedule look like year by year
What cash value is guaranteed and what is only projected
What happens if I need to reduce or stop paying premiums
How do loans work and what interest rate applies
What keeps this policy from becoming a modified endowment contract

If an agent avoids these questions or gives vague answers then that’s a signal to look elsewhere. Your money and your family’s protection are both on the line.

Review the policy every year

A permanent policy isn’t a set it and forget it product. Once a year ask the insurer for an in-force illustration. It shows how the policy is performing compared with the original projection. If the cash value is lagging you may need to pay more or adjust the plan before problems grow.

Check any loans and make sure interest is being managed. Confirm your beneficiaries are still correct. And look at whether your coverage still fits your life. A policy bought for one stage of life may need changes in the next.

Mistakes to avoid

Buying a permanent policy mainly because of a sales pitch about returns
Ignoring surrender charges and fees
Overfunding into MEC territory without knowing it
Borrowing heavily and letting the policy lapse
Skipping the guaranteed column in the illustration
Using money you may need in the next few years

Using life insurance to build wealth: where this leaves you

Take your time with this decision. A good agent will never rush you and a good policy will still be there next week.

It helps to remember that the best financial plan is one you can stick with for decades without stress.

Cash value life insurance isn’t a scam and it isn’t a magic wealth machine. It’s a financial product with real features and real costs. Treat it like any other big decision. Get the illustration. Ask hard questions. And compare it with simpler options before you sign.
