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
| Where to Buy | Pros | Cons |
|---|---|---|
| Online bank | Highest rates, no minimums, FDIC insured | No in-person banking |
| Traditional bank/credit union | In-person service, branch access | Much lower rates |
| Brokerage (brokered CD) | Secondary-market liquidity | Slightly lower rate, price risk |
For most people: online banks win. Compare current top picks at best CD rates 2026 — the leading institutions change over time. Note: Discover CD accounts are becoming Capital One CD accounts, so Discover is no longer a separate CD provider.
Step 3 — Choose Your Term
The term you choose should match when you will need the money:
| Timeline | Suggested CD Term |
|---|---|
| Less than 6 months | 3-month CD or no-penalty CD |
| 6–12 months | 6-month or 12-month CD |
| 1–2 years | 12-month or 18-month CD |
| 2–3 years | 24-month CD |
| 3–5 years | 36–60 month CD or CD ladder |
| More than 5 years | CD ladder + broader investment portfolio |
Compare the 1-year and longer-term rates at your bank to see what locking in longer costs or pays. 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:
- Go to the bank’s website and select “CDs” or “Certificates of Deposit”
- Choose your term and review the APY
- Enter your personal information (name, SSN, address, date of birth)
- Provide your funding source — a linked checking or savings account
- 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 (set by the bank; Ally and Capital One give 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)
| Rung | CD Term | APY (Popular Direct) | Matures | Interest Earned (own term) |
|---|---|---|---|---|
| 1 | 12 months | 4.50% | After 1 year | $225 |
| 2 | 24 months | 4.70% | After 2 years | $481 |
| 3 | 36 months | 4.85% | After 3 years | $763 |
| 4 | 48 months | 4.95% | After 4 years | $1,066 |
| 5 | 60 months | 5.00% | After 5 years | $1,381 |
Total interest: approximately $3,917 over five years, if each rung is held to its own original maturity (rates as of October 5, 2026; Popular Direct asks $10,000 per CD, so the $5,000 rungs only illustrate the math; confirm current rates before opening)
When Rung 1 matures after one year, you reinvest that roughly $5,225 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. On the bank pages we read in October 2026, 12-month rates ran from 3.50% to 4.50% — 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
Large branch-based banks vary widely by term and often pay less than online banks, so compare their published rate for your term. 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
| Mistake | What to Do Instead |
|---|---|
| Locking emergency fund in a CD | Keep 3–6 months expenses in a liquid HYSA |
| Choosing the longest term without rate research | Compare rate by term — sometimes 12-month beats 5-year |
| Ignoring early withdrawal penalties | Match term to your timeline or use no-penalty CDs |
| Auto-renewing without checking rates | Set maturity calendar alert; compare rates at renewal |
| Exceeding FDIC limits at one bank | Spread deposits across multiple banks if over $250,000 |
| Buying from a big-four bank without comparing | Online banks pay 4–10x more |
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?
CDs make sense as a guaranteed-return component of a savings strategy. They can pay more than a savings account (the FDIC national average savings rate was 0.38% as of October 19, 2026) and lock in today’s rate in case rates fall. 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.
