How to Invest in CDs 2026 — Step-by-Step Guide to Buying Certificates of Deposit

Investing in CDs is straightforward: choose a bank, pick a term, open an account, and deposit your money. You earn a fixed interest rate for the full term — no market risk, no volatility. At maturity you receive your original deposit plus all interest earned.

This guide covers where to buy CDs, how to pick the right term, a five-rung ladder example, and how CD interest is taxed.

Step-by-Step: How to Invest in a CD

Step 1 — Decide How Much to Invest

Determine how much money you can set aside without needing access before the CD matures. CDs are poor choices for emergency funds — that money belongs in a liquid high-yield savings account.

A practical split: keep 3–6 months of expenses in a HYSA, then invest any remaining surplus in CDs.

Step 2 — Choose Where to Buy

For most people: online banks win. Compare current top picks at best CD rates 2026 — the leading institutions change over time. Note: Discover Bank merged into Capital One in May 2025 and no longer accepts new CD applications; its former accounts now fall under the Capital One 360 brand.

Step 3 — Choose Your Term

The term you choose should match when you will need the money:

As of September 2026, top rates across 1-to-5-year terms are fairly close, which lowers the cost of locking in longer. The CD rate forecast 2026 covers where rates are expected to move.

Step 4 — Open Your CD Account

Most online banks let you open a CD entirely online in under 10 minutes:

1. Go to the bank’s website and select “CDs” or “Certificates of Deposit”
2. Choose your term and review the APY
3. Enter your personal information (name, SSN, address, date of birth)
4. Provide your funding source — a linked checking or savings account
5. Review and confirm your deposit

You will receive confirmation by email. The CD start date is typically the business day after funding clears.

Step 5 — Fund the CD

Most banks transfer funds via ACH from your linked account. Funding takes 1–3 business days. The rate is locked at the time of account opening, not when funds arrive.

Important: Standard CDs are closed to additional deposits. Once opened, the balance is fixed for the term.

Step 6 — Track Your Maturity Date

Set a calendar reminder 2 weeks before your CD matures. At maturity you will have a grace period (typically 7–10 days) to:

• Withdraw and spend or invest elsewhere
• Reinvest in a new CD at the current rate
• Transfer to a savings account

Most banks auto-renew CDs if you miss the grace period. The new rate may be lower than your original rate. See what to do when your CD matures.

CD Laddering: The Optimal Strategy for Most Investors

Instead of putting all your money in one CD, a CD ladder staggers maturities so you always have a CD coming due and access to the highest long-term rates.

Classic 5-Rung CD Ladder Example

Total investment: $25,000 (split into five $5,000 CDs)

Total interest: approximately $3,519 over five years, if each rung is held to its own original maturity (figures use the APY compounding convention; confirm current rates before opening)

When Rung 1 matures in September 2027, you reinvest that roughly $5,218 into a new 5-year CD at whatever rate is available then. Every year afterward, you have a CD maturing — giving you annual liquidity — while the longer rungs continue earning their locked-in rates.

Where to Buy CDs: Banks, Credit Unions, and Brokerages

Online Banks

Online banks offer the highest CD rates because they have lower overhead than branch-based banks. As of September 2026, top rates at online banks run roughly 4.30%–4.44% APY for 12-month CDs — check current offers, since this changes regularly.

Minimum deposits are often $0 at competitive online banks, though some top-rate offers require $500–$10,000 — check the specific institution’s minimum.

Traditional Banks and Credit Unions

Big four banks (Chase, Bank of America, Wells Fargo, Citibank) typically offer CD rates of 0.01–1.00% APY — a fraction of what online banks pay. Credit unions offer share certificates with competitive rates and NCUA insurance identical in coverage to FDIC.

Brokered CDs

Brokered CDs are sold through brokerage platforms (Fidelity, Schwab, Vanguard). They can be sold on the secondary market before maturity without the bank’s early withdrawal penalty — though the price may be above or below face value. Best for investors who want CD-like safety inside a brokerage account. The SEC has published investor guidance on brokered CDs.

How CD Interest Is Taxed

CD interest is taxable as ordinary income — the same rate as your paycheck, not the lower capital gains rate.

Key rules:

• Taxed in the year credited to your account, even if you don’t withdraw
• Bank issues Form 1099-INT each January for the prior year’s interest
• CDs spanning two years create tax liability in both years
• Interest above $1,500 requires Schedule B on your tax return

Tax-advantaged alternative: Hold CDs inside a traditional IRA (taxes deferred until withdrawal) or Roth IRA (qualified withdrawals tax-free). See IRA vs CD 2026.

Common CD Investing Mistakes

FDIC and NCUA Protection

All standard CDs at FDIC-member banks are insured up to $250,000 per depositor per bank per ownership category. Married couples can hold up to $500,000 at a single bank in joint ownership. To insure more, spread funds across multiple banks.

Credit union share certificates are covered by NCUA insurance with identical limits.

For balances over $250,000, use the FDIC’s BankFind suite to confirm a bank’s insurance status before opening.

Are CDs Worth It in 2026?

At roughly 4.30%–4.44% APY (Sept 2026), CDs make sense as a guaranteed-return component of a savings strategy. They outperform traditional savings accounts by a wide margin and lock in today’s rate in case the Fed resumes cutting. They are not a replacement for equity investments — but they are a reasonable tool for money you need in 1–5 years with zero tolerance for loss.
