You've saved 200,000, but a savings account pays almost nothing and locking all of it in a 3-year CD worries you in case you need cash. This is the real dilemma for many savers. Large-denomination certificates of deposit pay more than regular fixed deposits, but they start at a 200,000 minimum and reward longer terms. How do you capture the higher rate while staying flexible? The answer is the CD ladder. Let's break down the math and the strategy.
How CD Returns Are Calculated: Simple Interest and Term Choice
CD interest is calculated as simple interest: interest = principal × annual rate × term (in years). On 200,000: at a 1-year rate of 1.7%, interest = 200,000 × 1.7% × 1 = 3,400; at a 3-year rate of 2.6%, interest = 200,000 × 2.6% × 3 = 15,600. Note that CDs pay principal and interest at maturity in a lump sum — it's not compounding — so a 2.6% three-year rate is simply 2.6% per year, not 2.6% compounded.
Longer terms pay more, but the liquidity sacrifice grows too. Typical reference rates: about 1.5%-1.8% for 1 year, 1.8%-2.1% for 2 years, 2.3%-2.7% for 3 years, with some smaller banks near 3%. At the same bank, a 5-year CD is not necessarily higher than 3-year — rate inversions happen, so always compare the posted rates before depositing. To see what 200,000 earns at different rates, use the percentage calculator for the interest share, or the compound interest calculator to model what happens if you reinvest each year's interest.
| Term | Reference Rate | Interest on 200k | Characteristics |
|---|---|---|---|
| 1 year | About 1.7% | 3,400 | Flexible, easily transferable |
| 2 years | About 2.0% | 8,000 | Balanced |
| 3 years | About 2.6% | 15,600 | Higher yield, long lock-in |
| 5 years | About 2.5%-2.8% | 25,000-28,000 | Watch for rate inversion |
The CD Ladder: How to Split 200,000 Across Maturities
The core idea of a CD ladder: split one lump sum into CDs of different terms so that one matures every year, balancing yield and liquidity. On 200,000, split into three: 60,000 for 1 year, 70,000 for 2 years, and 70,000 for 3 years. When the 1-year CD matures in year one, if you don't need the money, roll it into a 3-year CD — from year two on, one high-rate 3-year CD matures every single year, on a rolling cycle.
Run the numbers: year-one interest = 60,000×1.7% + 70,000×2.0% + 70,000×2.6% = 1,020 + 1,400 + 1,820 = 4,240. In year two, the first CD rolls into 3-year, so all three are at the 3-year rate and each subsequent year pays about 200,000 × 2.6% = 5,200. Compared with 3,400 a year on an all-1-year approach, the ladder earns roughly 1,800 more per year — and still has money maturing annually for liquidity. Tune the split to your cash-flow needs: expect near-term spending, enlarge the 1-year slice; otherwise favor 3-year.
Advanced play: combine the ladder with a transferable CD. Put 150,000 into three ladder rungs and buy 50,000 in a transferable CD — you keep the long-term rate while retaining an emergency buffer. To model different splits and their annual cash flows, use the CAGR calculator or the percentage calculator to lay out each rung's share of principal before deciding how to slice.
CD Liquidity: Transfer vs. Early Withdrawal
The CD's biggest advantage isn't just the rate — it's transferability. Many banks let you list a CD for sale at the counter or in the mobile app: you transfer it to another buyer, possibly at a market premium or discount, which is usually far better than an early withdrawal. Early withdrawal typically pays only the demand-deposit rate — cash out a 3-year CD held for 2.5 years and the 2.6% rate collapses to about 0.2%, a heavy loss.
So before touching the money, choose your exit carefully: if you need cash and the transfer market is active, list the CD for sale first; if it's a short bridge of a few days, consider a CD pledge loan (some banks offer it at a rate below the withdrawal penalty). Before buying, ask three questions: does this CD support transfer, what's the transfer fee, and how is early withdrawal interest calculated — banks differ a lot.
One last reminder: CDs under 500,000 are covered by deposit insurance, so they're very safe, but a 3-year lock means that money is untouchable for 3 years. If you might need it within a year, don't chase the 3-year rate — pick 1-year or a money market fund instead. The goal of saving is "available when you need it," with yield second. To weigh CDs against other stable products over the long run, use the compound interest calculator and the CAGR calculator to compare annualized returns before deciding.
FAQ
Q1: What's the difference between a CD and a regular fixed deposit?
CDs have a high minimum (often 200,000), usually pay more, and are often transferable; regular fixed deposits have a low minimum, pay less, and generally can't be transferred. Both are covered by deposit insurance up to 500,000.
Q2: What if I need the money mid-term?
List the CD for sale first — usually better than an early withdrawal. A CD pledge loan can bridge a short gap. Early withdrawal typically pays only the demand rate, so check the rules before you buy.
Q3: Is a ladder better than putting everything in a 3-year CD?
All-in-3-year earns slightly more in the first three years (no low-rate rungs) but is illiquid — any need for cash in years one or two forces a costly early withdrawal. The ladder earns a bit less but frees up cash every year. For a balance of yield and liquidity, choose the ladder.
Q4: Do CD rates stay fixed?
No. CD rates track the market; the rate is locked at purchase, and later rate cuts don't affect already-issued CDs. But at maturity you renew at the then-current rate, so in a falling-rate environment, lock in the longest term you can.
