A certificate of deposit, or CD, is one of the simplest savings products a bank offers: you give the bank a lump sum for a fixed period — three months, a year, five years — and the bank pays you a fixed interest rate for the whole term. The rate cannot change, the return is known in advance, and the deposit is insured by the federal government up to $250,000. The catch is the lock-in: take the money out early and you pay a penalty, usually several months of interest. That trade — certainty in exchange for flexibility — is the whole story of CDs, and this guide explains when it is worth making.
This guide explains how certificates of deposit work, what rates to expect, the types of CD available, how CD laddering keeps some of your money accessible, and when a CD beats a savings account — and when it does not. It is general educational information only, not personal financial advice. The insurance and rate figures below come from the Federal Deposit Insurance Corporation (FDIC) and the National Credit Union Administration (NCUA).
What Is a Certificate of Deposit?
A certificate of deposit is a time deposit: you agree to leave a lump sum with a bank or credit union for a fixed term, and the institution agrees to pay you a set interest rate for that entire term. Neither side can change the rate once the contract begins. At the end of the term — the maturity date — you get your original deposit back plus all the interest it earned. You can then withdraw it, roll it into a new CD, or move it elsewhere. Many CDs renew automatically into a new CD of the same term if you do nothing, which is why banks give you a short grace period after maturity, often around a week to ten days, to act without penalty.
Most CDs have a minimum deposit, which varies by bank and is disclosed upfront — often $500 or $1,000 at traditional banks, and sometimes $0 at online banks. Common terms run from three months to five years, with one-year CDs the classic middle ground. The rate is fixed when you open the account and does not change, so you know your exact return before you commit a single dollar. That certainty is the CD’s main advantage over a savings account, whose rate the bank can cut at any time. Our guide to checking account benefits covers the account your CD money usually comes from and returns to.
The safety story is the same as any bank deposit. CDs at FDIC-insured banks are protected up to $250,000 per depositor, per insured bank, for each ownership category, and CDs at credit unions carry the same $250,000 protection through the NCUA. One detail catches people off guard: accrued interest counts toward that $250,000 cap, not just your original deposit. If you hold more than $250,000 in CDs at one bank, only $250,000 is insured — split large deposits across multiple banks to keep everything covered. Before opening a CD, confirm the institution is actually insured, using the FDIC’s BankFind tool or the NCUA’s credit union locator.
How CD Rates Work
CD rates follow the Federal Reserve’s benchmark rate, so the rates available today will not be the same next month. When the Fed raises rates, new CDs pay more; when it cuts, new CDs pay less. But the rate on a CD you already own never changes — that is the point of the product. If you lock in 4% for five years and rates fall to 2%, you keep earning 4%. If rates rise to 6%, you are stuck at 4% until the term ends, which is the risk you accept in exchange for the certainty.
National average rates are much lower than the best rates on the market, and the gap is worth knowing. As of March 2026, the FDIC’s national averages sit around 1.52% for a 12-month CD, 1.31% for a 36-month term, and 1.34% for a 60-month term. Online banks and credit unions routinely pay several times those averages, because they have no branches to fund. The lesson is to shop: the difference between the national average and a competitive rate on a $10,000 CD is hundreds of dollars a year, for the same product, with the same insurance.
The maths is straightforward. Put $10,000 in a one-year CD at 4% and you earn $400. Put the same $10,000 in a five-year CD at 4.5%, compounded annually, and it grows to about $12,462 — $2,462 of interest. At 4% for five years it reaches about $12,167, or $2,167 of interest. Compare that with a savings account paying 0.5%: the same $10,000 earns $50 in a year. The CD pays eight times as much, and the only thing it asks in return is that you leave the money alone. Our guide to how to save money fast on a low income shows where the lump sum for a first CD can come from.
Types of CDs
The traditional CD is the baseline: a fixed term, a fixed rate, a penalty for early withdrawal. Everything else is a variation on that contract. A no-penalty CD, sometimes called a liquid CD, lets you pull out your full balance and earned interest without any forfeiture, usually after the first six or seven days. The rate is lower than a traditional CD of the same term — the bank charges for the flexibility — but it is a useful halfway house if you want a better rate than savings without a hard lock-in.
A bump-up CD, also called a raise-your-rate CD, lets you increase your interest rate once during the term if rates rise. You start at a slightly lower rate than a traditional CD, and if the bank’s rates go up, you ask for the bump and keep the higher rate for the rest of the term. It is a hedge against the main risk of a CD — locking in just before rates rise — but it only helps once, and only if rates actually rise. A jumbo CD is simply a CD with a large minimum deposit, often $100,000, which usually pays a slightly higher rate than a standard CD of the same term.
A brokered CD is bought through a brokerage firm rather than directly from a bank. It still carries FDIC insurance up to $250,000 per depositor at the issuing bank, but it works differently: you cannot withdraw early by paying a penalty, you have to sell it on the secondary market, and the price you get depends on current rates. If rates have risen, the CD is worth less than you paid. Brokered CDs suit investors who are comfortable with that trade-off and want to hold CDs from several banks in one account. An IRA CD is a CD held inside an individual retirement account, so the interest grows tax-deferred — the same product, in a different tax wrapper. Our guide to retirement accounts explains the IRA side of that choice.
CD Laddering: How to Keep Access Without Giving Up Yield
The standard answer to the CD’s flexibility problem is the ladder, and it is genuinely elegant. Instead of putting $10,000 into one five-year CD, you split it into five $2,000 CDs with terms of one, two, three, four, and five years. Every year, one CD matures — and you roll it into a new five-year CD at whatever the current rate is. After the ladder is built, you hold five five-year CDs maturing one year apart: you get the higher rates that typically come with longer terms, but a chunk of money frees up every twelve months.
The ladder solves two problems at once. First, it gives you regular access to some of your money without early withdrawal penalties — if you need cash in a given year, you take it from the maturing CD and do not renew it. Second, it lets you take advantage of rate changes. If rates rise, you reinvest the maturing CD at the higher rate. If rates fall, you still hold other CDs earning the old, higher rate. The ladder is not a way to beat the market; it is a way to stop guessing which way rates will move, by spreading the decision across five years instead of making it once.
Building a ladder is simple. Decide the total amount, divide it equally across the rungs, and open the CDs on the same day. With $10,000, that is five CDs of $2,000. With $25,000, five of $5,000. The rungs do not have to be one year apart — a ladder of three-month, six-month, nine-month, and twelve-month CDs works the same way for money you may need sooner — but the one-to-five-year version is the classic, because it matches the terms where the rate premium for locking up is largest. Keep the ladder in one bank if you like, or spread it across banks to stay under the $250,000 insurance limit and to chase the best rate on each rung.
Early Withdrawal Penalties
Break the deal early and the bank takes a penalty — that is the mechanism that makes the bank confident enough to offer you a fixed rate. Federal regulation defines a time deposit as requiring at least a seven-day interest penalty on early withdrawals, under Regulation DD, and most banks charge far more than the minimum. The standard structure is a forfeiture of several months of interest: a typical penalty on a one-year CD is three months of interest, and on a five-year CD it is often six months or a full year of interest. The exact formula varies by bank and is spelled out in the account disclosures — read it before opening, not when you need the money.
The numbers make the cost concrete. On a $10,000 CD earning 4%, a three-month penalty costs $100 — three months of interest. On a $10,000 CD earning 4.5%, a six-month penalty costs $225. If you withdraw very early from a five-year CD, the penalty can exceed the interest earned so far, which means you get back less interest than you have earned — though the penalty comes out of your interest first, and most banks will not take your original principal except in extreme cases. Federal rules carve out two situations where the bank can waive the penalty entirely: the death of an account owner, or a court determination that an owner is legally incompetent.
The practical rule is simple: only put money in a CD that you are confident you will not need before maturity. Emergency funds do not belong in a CD — they belong in a high-yield savings account, where they are available the same day. Money for a known future expense — a house deposit in two years, a car in eighteen months, a tax bill in six — is ideal CD money, because the date is fixed and the rate is fixed to match it. Our guide to smart ways to save money on groceries is one place to find the money for a first CD without touching the emergency fund.
CDs vs Savings Accounts, Money Markets, and Bonds
A CD beats a savings account on rate and loses on access. A savings account lets you withdraw at any time, but the bank can cut its rate whenever it likes — and usually does, the moment the Fed cuts. A CD locks the rate in, so the return is certain, but the money is locked too. The choice is really a question about the money: if you might need it next month, take the savings account; if you know you will not need it for a year, take the CD and the extra interest.
A money market account sits between the two: it pays a variable rate like a savings account, but usually a higher one, and it comes with cheque-writing and debit card access. It suits money you want to keep liquid but earning more than a basic savings account pays. A bond is a different animal altogether: you lend money to a government or a company, the rate is fixed, but you deal with a secondary market rather than a bank, and there is no FDIC insurance. A bond’s price falls when rates rise, so a bond fund can lose money in a year when a CD cannot. For money that must not lose value, the CD’s combination of a fixed rate and federal insurance is hard to beat. Our guide to types of investments puts CDs in the wider picture of where savings can go.
The honest summary is that a CD is a tool for a specific job: parking money you will need on a known date, at a known return, with no risk to the principal. It is not an investment — it will not make you rich, and over long periods it barely keeps up with inflation. But it is the right tool for the job it does, and for money with a deadline, it is usually the best-paying safe option available.
Frequently Asked Questions
what is a certificate of deposit
A certificate of deposit (CD) is a savings account where you agree to leave a lump sum untouched for a fixed period — typically three months to five years — and the bank pays you a fixed interest rate in return. You know exactly how much interest you will earn before you deposit a single dollar. If you withdraw early, you pay a penalty, usually a portion of the interest you would have earned. CDs at FDIC-insured banks are insured up to $250,000.
are cds safe
Yes, at an insured institution. CDs at FDIC-insured banks are protected up to $250,000 per depositor, per insured bank, per ownership category, and the NCUA provides the same protection at credit unions. Accrued interest counts toward the $250,000 cap, so split deposits above that amount across multiple banks. The rate is fixed and the principal is guaranteed, so a CD cannot lose value the way a bond or a stock can.
what happens if i withdraw from a cd early
You pay an early withdrawal penalty, usually expressed as a number of months of interest — typically three months on a one-year CD and six months to a year on a five-year CD. Federal rules require a minimum penalty of seven days’ interest. On a $10,000 CD at 4%, a three-month penalty costs $100. The penalty comes out of your interest first. Banks can waive it on the death of an owner or a court finding of legal incompetence.
what is a cd ladder
A CD ladder is a strategy where you split your money across several CDs with staggered maturity dates — for example, five $2,000 CDs with terms of one, two, three, four, and five years. As each one matures, you roll it into a new five-year CD. Once built, you hold five five-year CDs maturing one year apart, so you get long-term rates with a chunk of money freeing up every year, and you reinvest at current rates as each rung matures.
are cd rates better than savings account rates
Usually, yes — often by a wide margin. As of March 2026, the FDIC national average for a 12-month CD is about 1.52%, against a typical savings account rate well under 1%, and competitive online banks pay several times the national average on CDs. On $10,000, a 4% CD earns $400 in a year while a 0.5% savings account earns $50. The price of the higher rate is the lock-in: the money is not available until maturity without a penalty.
The Bottom Line
A certificate of deposit trades flexibility for certainty: you lock a lump sum away for a fixed term, the bank locks the rate in, and the FDIC insures the deposit up to $250,000. On $10,000, a 4% one-year CD earns $400, and a 4.5% five-year CD grows to about $12,462 — far more than a savings account pays, and with no risk to the principal. The cost is the early withdrawal penalty, typically three months of interest on a one-year CD and six months or more on a five-year CD, so only deposit money you will not need before maturity. Use a ladder — five CDs maturing one year apart — to keep some money accessible while earning long-term rates, and shop beyond the national averages, where online banks routinely pay several times the FDIC’s 1.52% average for a 12-month CD. For money with a known date and a known purpose, a CD is usually the best-paying safe place to keep it.
