How to Stack FDIC Coverage Above $250K
The Stacking Math — How Categories Multiply Coverage
Most savers think FDIC's $250K limit caps them at $250K per bank. It doesn't. The limit applies per ownership category. There are eight categories. A single individual at one bank can structure roughly $1M of coverage. A married couple can reach $1.5M-$2M. A couple with adult children named as beneficiaries can structure $3M+ at a single institution. Above that level, even aggressive trust stacking gets administratively painful, and most planners recommend spreading across multiple banks or using CDARS/ICS networks.
The eight FDIC ownership categories:
- Single accounts (one owner, no beneficiaries)
- Joint accounts (two or more co-owners)
- Certain retirement accounts (IRA, SEP, SIMPLE)
- Revocable trust accounts (POD accounts, formal living trusts)
- Irrevocable trust accounts
- Employee benefit plan accounts
- Corporation/partnership/unincorporated association accounts
- Government accounts
Worked Example #1 — Single Saver, $500K
You're single, no kids, $500K to deposit. At one bank, your options:
| Account Type | Amount | Coverage |
|---|---|---|
| Individual CD | $250,000 | $250,000 ✓ |
| IRA CD | $250,000 | $250,000 ✓ |
| Total at one bank | $500,000 | $500,000 ✓ |
If you don't have $250K of qualifying IRA money, the second $250K goes to a second FDIC-insured bank — same individual category, separate institution, fresh $250K limit.
Worked Example #2 — Married Couple, $1.5M
You and your spouse have $1.5M to deposit. Both have IRAs. Both want to stay with one bank for simplicity. The stack:
| Account Type | Amount | Coverage |
|---|---|---|
| Your individual CD | $250,000 | $250,000 ✓ |
| Spouse's individual CD | $250,000 | $250,000 ✓ |
| Joint CD (both names) | $500,000 | $500,000 ✓ ($250K per co-owner) |
| Your IRA CD | $250,000 | $250,000 ✓ |
| Spouse's IRA CD | $250,000 | $250,000 ✓ |
| Total at one bank | $1,500,000 | $1,500,000 ✓ |
Five accounts, one institution, fully insured. The bank may push back on opening this many CDs (it's operationally annoying for them), but it's your right under FDIC rules.
Worked Example #3 — Couple With Two Beneficiaries, $2.5M
Same couple, now with $2.5M and two adult children they want as beneficiaries. Add revocable trust (POD) accounts:
| Account Type | Amount | Coverage |
|---|---|---|
| Your individual CD | $250,000 | $250,000 ✓ |
| Spouse's individual CD | $250,000 | $250,000 ✓ |
| Joint CD | $500,000 | $500,000 ✓ |
| Your IRA CD | $250,000 | $250,000 ✓ |
| Spouse's IRA CD | $250,000 | $250,000 ✓ |
| Your POD CD (2 beneficiaries) | $500,000 | $500,000 ✓ ($250K × 2 beneficiaries) |
| Spouse's POD CD (2 beneficiaries) | $500,000 | $500,000 ✓ ($250K × 2 beneficiaries) |
| Total at one bank | $2,500,000 | $2,500,000 ✓ |
Seven accounts, fully insured. Coverage scales with the number of beneficiaries in revocable trust accounts — up to 5 unique beneficiaries with no further increase (above 5, more complex trust formulas apply).
When Stacking Stops Working — Practical Ceilings
Theoretically you can keep adding categories: corporate accounts (if you own a business entity), separate employee benefit accounts (if you have an SEP or solo 401(k)), more beneficiaries on POD accounts. In practice, three things cap the strategy at one bank:
- Operational complexity. Managing 10+ CDs at one bank with different maturities, different beneficiary designations, and different ownership structures is a job. When you die or are incapacitated, your spouse has to navigate it.
- Beneficiary qualification rules. Above 5 POD beneficiaries, the coverage math switches to a formula based on the value of each beneficiary's non-contingent interest in the trust. It works, but it requires careful documentation.
- Auditability. If the bank fails, the FDIC's resolution team will work through your account titling. Clean titling = fast payout. Messy titling = delayed payout.
For depositors above $2M-$3M who insist on single-institution simplicity, the answer is usually CDARS or ICS — networks where one bank places your deposit across dozens of partner banks, each below the $250K limit, with a single statement.
CDARS, ICS, and the Multi-Bank Alternative
The Certificate of Deposit Account Registry Service (CDARS) and the Insured Cash Sweep (ICS) are networks operated by IntraFi (formerly Promontory Interfinancial Network). When you deposit a large balance with a CDARS- or ICS-member bank, that bank places your funds across dozens or even hundreds of other member banks in $250K-or-less slices, each fully FDIC-insured at the recipient bank. You get one statement from your primary bank; you stay insured up to $50M+ in some cases.
The trade-off: CDARS and ICS rates are often slightly below the best direct-bank CD rates because the participating banks share margin with the network. For depositors who can rate-shop direct, stacking ownership categories at 2-3 banks often beats CDARS economically. For depositors who value a single statement and don't want to manage relationships across multiple banks, CDARS/ICS is the cleanest path. We compare the two in detail on the CDARS explainer and the ICS guide.
Where MYGAs Enter the Picture
For savers with $500K+ in fixed-income allocation, multi-year guaranteed annuities offer a structurally different safety model. MYGAs are insurance contracts backed by the issuing carrier's general account and the state guaranty association (typically $250K-$300K per owner per carrier). Splitting $1M across three A-rated carriers gives you guaranty fund coverage on each layer without requiring trust or beneficiary gymnastics, and current MYGA yields (5.5-6.0% in mid-2026) typically beat the best 5-year FDIC-insured CDs by 50-100 basis points.
MYGAs aren't a CD replacement for everyone — they have surrender charges and a narrower liquidity profile. But for the bucket of money you've decided to lock up for 3-7 years anyway, they belong in the comparison.
