Here’s why you ought to seriously consider taking Social Security at 62. Even if the 'basic' math suggests otherwise

However, even this analysis has limitations. It typically doesn’t account for the time value of money, or the opportunity cost of accessing and investing earlier benefits.

Beware the opportunity cost

If you retire at 62 but delay claiming Social Security until 67, you may have to rely on withdrawals from your savings or tax-advantaged accounts like your 401(k) to cover living expenses. By doing so, you’re forgoing the potential investment returns those funds could have earned if left untouched.

This trade-off is known as opportunity cost, and it’s an important factor to consider in retirement planning.

When you factor opportunity cost into your breakeven analysis, the age at which delaying benefits becomes advantageous can be pushed significantly further out.

For example, someone eligible for $2,000 per month at their full retirement age of 67, assuming a 5% annual return on their investments, would need to live approximately 88 years and eight months to reach the breakeven age.

If the expected return is 8% annually, the breakeven point may not be reached within a typical lifespan. In other words, claiming benefits earlier while keeping retirement savings invested could yield a better financial outcome in this scenario.

But there are ways to decrease the opportunity cost once you’re aware of your breakeven point.

Use your emergency fund to bridge the gap

If you prefer to delay Social Security, you’ll need a significant emergency fund saved up to avoid taking money out of your investments for as long as possible. Of course, with that much money stored away, you’ll want to ensure it’s keeping up with inflation.

A high-yield account like the Wealthfront Cash Account can be a great place to grow your emergency fund, since it offers competitive interest rates and easy access to your cash when you need it.

A Wealthfront Cash Account can provide a base variable APY of 3.50%, but Moneywise readers can receive a 0.65% boost over their first three months for a total APY of 4.15%. That’s over ten times the national deposit savings rate, according to the FDIC’s October report.

With no minimum balances or account fees, 24/7 withdrawals and free domestic wire transfers, your funds remain accessible at all times. Plus, Wealthfront Cash Account balances of up to $8 million are insured by the FDIC through program banks.

Consider a HELOC if the math makes sense

For homeowners, another way to avoid the opportunity cost that comes from using your tax-sheltered investment funds early is a home equity line of credit (HELOC).

You’ll want to run the numbers with a financial advisor first to make sure you come out ahead, but if the math works, a HELOC could provide an alternative that allows you to keep your 401(k) and IRA invested longer while still retiring early.

HELOCs can give you extra financial flexibility by using your home's equity as collateral. With this in mind, it’s important to have a clear repayment strategy that you can commit to. Typically, your home will also need significant equity to make the flexibility from a HELOC worthwhile.

What else can retirees do?

Because the basic math behind Social Security decisions often overlooks key variables — and estimating factors like investment returns and longevity is inherently uncertain — working with a qualified financial advisor can be a smart move.

A professional planner can help you account for additional considerations such as inflation, estate planning, health care costs and annual spending needs.
