After you’ve done the hard work of creating a strong financial foundation – setting up a retirement account, establishing an emergency fund, purchasing a home – you may be wondering what to do next with your money.

Are stocks best? What about real estate or mutual funds?

Even with discretionary income to put toward savings, it’s easy to be skeptical about whether investing in the market is worth the risk.

One way savers can benefit from accrued interest while minimizing risk and maintaining a relatively high degree of liquidity is through a clever investment practice known as certificate laddering. It involves using traditional Certificates as a means to build wealth over time.

It may be just the right fit if you’re looking for a way to grow your net worth while always keeping an extra cushion in reserve for financial emergencies.

What you’ll learn

Savings Certificate basics

Before setting up a Certificate ladder, it’s essential to have a basic understanding of how Certificates work.

In summary, a certificate, often known as a CD is a type of savings account that pays a set interest rate when a fixed amount of money is invested over a specific period. Savers agree to keep their funds invested in a certificate for the entire term. In return, they’re guaranteed to receive interest at a specific rate for the term, even if overall interest rates trend down during that time.

Certificates range in size, terms and interest rates. Standard certificate terms last at least 3 or 12 months but can last up to five years or more. Generally, the longer you agree to invest your funds, the higher the interest rate you’ll receive at the end of the certificate’s term.

Keep in mind that Certificates are a highly secure investment because they’re insured up to $250,000 by the National Credit Union Administration (credit unions) or Federal Deposit Insurance Corporation (banks).

How certificate ladders work

Certificate laddering works by investing one lump sum in multiple certificates – some short-term, some medium-term and some long-term – with staggered maturity dates, typically at equal intervals.

When the shortest-term certificate matures, you reinvest the funds from that certificate into a new one that matches the length of the longest-term certificate from the set you initially opened. In doing so, you benefit from interest rates while maintaining access to funds, as there’s consistently a certificate approaching full term.

What it looks like in practice

Pretend you have $20,000 stashed away in a simple savings account. You divide that cash into five equal portions and open certificates in 12-month intervals. In other words, you open five $4,000 certificates set to mature in 12, 24, 36, 48 and 60 months, respectively.

  • When your first certificate matures at the 12-month, you roll it over into a new five-year certificate. Why five years? Because when you started the certificate ladder process, your longest certificate term was 60 months.
  • When the 24-month certificate matures, you buy another five-year note.
  • After the 36-month certificate matures, you do the same, and so on.

After five years have passed, you’ll have five 60-month certificates, each potentially earning a higher interest rate. The beauty is that because all are set to mature at the same 12-month interval, you’ll never be more than 12 months away from withdrawing funds.

Keeping reserves for emergencies

While certificate ladders provide flexibility, they’re not the same as cash. Because of this, savers should strive to have at least two months of living expenses tucked away in a high-rate savings account before they commit a substantial portion of their resources to a certificate ladder. This will not only keep you protected in an emergency but will help you avoid both the headache and lost interest of withdrawing a certificate before its maturity date.

It’s okay to get creative

Just because most certificate ladders are set up with round numbers at easy-to-remember intervals doesn’t mean you need to stick to that script. Talk with your credit union or bank about their certificate options and consider your unique financial situation before getting started.

By adjusting the dollar value of each certificate or selecting various maturity intervals, you may even find that you’re more comfortable contributing additional funds over time. If you commit to the plan, you can be sure you’re always one rung away from cashing in a handsome return on investment.
