The verdict: CIT Bank Platinum Savings pays 3.75% APY — but only on balances of $5,000 or more. Below that line, the entire balance earns 0.25% APY, which makes it one of the worst savings accounts for a small balance and one of the better ones for a large, stable one. If you will keep $5,000 or more there every single day, it beats Marcus (3.50% APY) and Ally (3.10% APY) on rate, charges no monthly fee, and is backed by First Citizens Bank. If your balance will ever dip under $5,000, choose an account without a tier.

How we researched this review
We checked nine primary documents: CIT Bank’s Platinum Savings page, its APY-boost promotion terms, its fee schedule, the FDIC’s BankFind record for First-Citizens Bank & Trust Company, the FDIC’s National Rates and Rate Caps, the FDIC’s deposit-insurance guidance, First Citizens’ announcement of the CIT merger, and the savings-rate pages of Marcus by Goldman Sachs and Ally Bank. Every rate and fee below comes from one of those documents and is dated.
We do not open or test bank accounts. Where CIT’s public pages don’t state something — current rates on its other products, for example, which load dynamically and could not be confirmed at the source — we say so rather than repeat numbers from other websites.
The $5,000 line: how the tiers really work
This is the most important thing to understand about Platinum Savings, and the part most summaries flatten into “up to 3.75% APY.”
CIT’s disclosure describes a tiered interest rate account that pays interest on the entire account balance, at the rate for whichever tier your end-of-day balance falls into. Two consequences follow:
- It is not a blended rate. At $5,000 or more, every dollar earns 3.75% APY — not just the dollars above $5,000.
- It is a cliff, not a slope. Finish a day at $4,999.99 and every dollar earns 0.25% APY for that day. One bill payment that pulls the balance under the line costs you most of that day’s interest on the whole account.
In yearly terms, assuming the balance and rate stay unchanged for a year (which is what APY measures):
| Balance | CIT tier APY | CIT interest / year | Same balance at 3.50% APY |
|---|---|---|---|
| $1,000 | 0.25% | $2.50 | $34.00 |
| $4,999 | 0.25% | about $12.50 | about $170 |
| $5,000 | 3.75% | $187.50 | $170.00 |
| $10,000 | 3.75% | $375.00 | $340.00 |
| $25,000 | 3.75% | $937.50 | $850.00 |
One dollar either side of $5,000 is the difference between roughly $12.50 and $187.50 a year. Above the line, CIT’s edge over an untiered 3.50% account is real but modest: $25 a year on $10,000, $62.50 on $25,000. Worth having if your balance is stable; gone the first month you dip below the tier. Our breakdown of how much interest $10,000 earns runs the same arithmetic across account types.
The 0.35% APY boost, in dollars
Per CIT’s promotion page, checked October 1, 2026:
- Boost: an extra 0.35% APY on the standard tiers for 6 months — 4.10% APY at $5,000 or more, 0.60% APY below.
- Code and window: CITBOOST, for accounts opened or enrolled between February 13 and October 31, 2026.
- Who: the page describes new accounts and existing Platinum Savings accounts enrolled with the code; custodial and trust accounts are excluded. Confirm eligibility when you enrol.
- Moves with the rate: if the standard APY changes, the boost stays 0.35% above it, on balances up to $9,999,999.
The honest way to value a boost is in dollars. Over six months, assuming rates hold:
| Balance | 6 months at 3.75% | 6 months at 4.10% | Extra from the boost |
|---|---|---|---|
| $5,000 | about $93 | about $101 | about $9 |
| $10,000 | about $186 | about $203 | about $17 |
| $25,000 | about $464 | about $507 | about $43 |
Worth typing the code if you are opening the account anyway; not a reason to choose the account. The promotional rate ends, and the standard rate is what you live with afterwards.
Fees
CIT’s fee schedule covers eChecking, savings and money market accounts together. The lines that matter for Platinum Savings:
| Activity | CIT Bank fee |
|---|---|
| Monthly service fee | $0 |
| Online transfer | $0 |
| Incoming wire | $0 |
| Overdraft / insufficient funds | $0 |
| Outgoing domestic wire (minimum $1,000) | Free with a balance of $25,000 or more; $10 per wire below $25,000 |
For anyone moving money by ordinary online transfer, this is a no-fee account. The $10 wire fee only applies when wiring out of a balance under $25,000. The schedule’s debit-card fees belong to eChecking, a separate CIT account — savings here is built to be reached by transfer, not by card.
Who owns CIT Bank, and how deposits are insured
CIT Bank is a division of First-Citizens Bank & Trust Company of Raleigh, North Carolina, which completed its merger with CIT Group on January 3, 2022, according to First Citizens’ own announcement. The bank is active and FDIC-insured under FDIC certificate 11063.
Deposits are insured up to $250,000 per depositor, for each account ownership category. The detail that catches people out is in CIT’s own disclosure: deposits at First Citizens and at any bank that is a division of it are not separately insured — they are added together. That follows the FDIC’s rule that one chartered bank gets one limit per depositor and ownership category, whatever names it trades under. With $200,000 already at First Citizens, putting $100,000 into Platinum Savings in the same ownership category leaves $50,000 uninsured.
On access: CIT lists electronic transfer, mail-in check and wire as funding methods, points customers to its mobile app, and references Zelle on the Platinum Savings page (a U.S. bank account is required). CIT’s contact page lists weekday and Saturday phone hours in Eastern time, with no Sunday phone support; online account access runs around the clock.
What we like and what to watch out for
What we like
- A top-of-market rate above the tier. 3.75% APY is higher than Marcus’s 3.50% and Ally’s 3.10% when we checked, and more than ten times the FDIC’s 0.37% national average.
- The whole balance earns the tier rate. No blended calculation at $5,000 or more.
- No monthly fee and a $100 opening minimum, so you can open it before you reach $5,000.
- Serious ownership, with the insurance position spelled out plainly in the disclosure.
Watch out for
- The $5,000 cliff. Below it, the entire balance earns 0.25% APY — lower than the FDIC national average, on an account marketed as high-yield.
- Insurance is shared with First Citizens. Existing First Citizens customers with large balances must add both together against the $250,000 limit.
- The rate is variable and dated July 1, 2026. It was still displayed on October 1, but nothing obliges CIT to keep it.
- No Sunday phone support, and a $10 outgoing-wire fee under $25,000.
Best for: savers holding a stable $5,000 or more — an established emergency fund, a house deposit in progress, cash waiting to be invested.
Skip it if: your balance is below $5,000, or swings below it when bills come out.
CIT vs Marcus vs Ally
Two common alternatives, both verified on their own sites this week. Neither has a balance tier, which is what makes the comparison useful.
| Account | APY | Rate as of | Balance tier? | Link |
|---|---|---|---|---|
| CIT Platinum Savings | 3.75% / 0.25% | July 1, 2026 (shown Sept 14) | Yes — $5,000 | CIT → |
| Marcus by Goldman Sachs | 3.50% | Oct 1, 2026 | No | Marcus → |
| Ally Online Savings | 3.10% | Oct 1, 2026 | No — $0 minimum, no monthly fees | Ally → |
The decision is mostly about your balance. Above $5,000 and stable, CIT wins on rate. Below $5,000, or with a balance that swings, Marcus’s flat 3.50% earns far more — about $175 a year on $4,999 against CIT’s $12.50. Ally pays the least of the three right now; its case rests on the wider banking relationship. See our Marcus vs Ally comparison and our best high-yield savings accounts roundup for the wider field.
CIT also sells Savings Connect, a Money Market account and a No-Penalty 11-Month CD. Their current rates load dynamically on CIT’s site and could not be confirmed at the source on October 1, 2026, so we have left them out. If a fixed rate appeals, our high-yield savings vs CD explainer covers when locking in makes sense.
Who should open it — and who should skip it
A good fit if you already have an emergency fund of $5,000 or more that you rarely touch; you are accumulating a specific sum — a house deposit, a tax bill — that only goes up until the day you spend it; or you are holding cash between investments and want a no-fee place to park it above the tier.
Skip it if you are starting from zero, because months spent building to $5,000 earn 0.25% APY while an untiered account pays the full rate from the first dollar (our emergency fund guide covers that early stage); if this is your only savings account and bills draw it down; or if you already hold large balances at First Citizens.
A sensible middle path: keep a working buffer in an untiered account and move only the money you won’t touch — comfortably above $5,000 — into Platinum Savings. For a lump sum, our guide to where to park $10,000 compares the options.
What this account doesn’t do
- It doesn’t lock in a rate. The APY is variable; if rates fall, yours falls. A CD is the tool for a guaranteed rate.
- It doesn’t replace checking. It is a place to hold money, not to spend from.
- It doesn’t extend FDIC coverage. Unlike sweep-style cash accounts that spread deposits across partner banks, this is one bank and one $250,000 limit, shared with First Citizens.
- It doesn’t grow wealth. It protects principal and earns interest; long-term growth is a job for investing.
If the harder part is the saving habit rather than the account, Morgan Housel’s The Psychology of Money is a readable book on why keeping cash set aside is more about behaviour than income.
Frequently asked questions
What is the CIT Bank Platinum Savings rate right now?
When we checked on October 1, 2026, CIT’s page showed 3.75% APY on balances of $5,000 or more and 0.25% APY on $0.01 to $4,999.99. CIT states those rates were accurate as of July 1, 2026, and that they are variable and may change at any time.
Do I earn 3.75% only on the money above $5,000?
No. Interest is paid on the entire balance at the rate for the tier your end-of-day balance falls into. At $5,000 or more the whole balance earns 3.75% APY; below $5,000 the whole balance earns 0.25% APY for that day.
Is CIT Bank FDIC insured?
Yes. CIT Bank is a division of First-Citizens Bank & Trust Company, FDIC certificate 11063. Deposits are insured up to $250,000 per depositor for each ownership category, but that limit is shared with money held at First Citizens Bank.
How much do I need to open an account?
$100. You only need $5,000 to earn the higher tier, not to open.
Does the CITBOOST promotion apply to existing customers?
CIT’s promotion page, as checked October 1, 2026, describes enrolling existing Platinum Savings accounts as well as opening new ones, and excludes custodial and trust accounts. It runs until October 31, 2026 and the boost lasts six months. Confirm eligibility on the promotion page when you enrol.
Does Platinum Savings charge any fees?
No monthly service fee, and online transfers, incoming wires and overdrafts are $0 on CIT’s fee schedule. The main fee you might meet is $10 for an outgoing domestic wire when your balance is under $25,000.
Bottom line
CIT Bank Platinum Savings is a good account with a sharp edge. For a stable balance of $5,000 or more it pays 3.75% APY with no monthly fee, beating Marcus and Ally on rate when we checked. For anything smaller it pays 0.25% APY, which is worse than the national average.
So the review comes down to one question: will this balance stay above $5,000 every day? If yes, open it, use the CITBOOST code, and count anything you hold at First Citizens against the insurance limit. If no, pick an account without a tier — you’ll earn more.
