For the full APY comparison framework and account selection guide, see the High-Yield Savings hub.
High-yield savings accounts pay 8-40x more interest than traditional bank savings as of September 2026 — but do they require large deposits to get started? Here’s every minimum requirement you need to know. Note: Discover Bank is no longer accepting new savings account applications — it merged into Capital One, N.A. on May 18, 2025, and is excluded from the tables below. See the Discover Bank status guide for details on existing accounts.

Tiered-Rate Banks (Different APY by Balance)
Some banks advertise a high top-tier APY but pay much less below a threshold. Illustrative example using rates in the current 2.50%-4.10% range:
Balance
Illustrative Tiered Bank
Blended (Effective) APY
$10,000
2.50% under $5K, 3.25% $5K-$25K
2.87% (blended on $10K)
$50,000
adds 3.75% tier $25K-$100K
3.42% (blended on $50K)
$100,000
adds 4.10% tier above $100K
3.59% (blended on $100K)
The takeaway: A flat-rate bank at 3.00% can outperform a tiered bank advertising “up to 4.10%” if most of your balance falls in lower tiers. CIT Bank’s own Platinum Savings is the clearest real-world example: it pays 0.25% below $5,000 and only reaches its 3.75-4.10% range above that threshold.
How to Spot Tiered Rates
Look for these phrases in account disclosures:
“Up to X% APY” — almost always tiered
“Earn X% on balances above $5,000/$25,000” — tiered
“Blended rate” or “rate tiers” — tiered
Banks that advertise a single APY without “up to” (Ally, Bread, Marcus, Synchrony) typically offer flat rates.

For most other mainstream high-yield savings accounts on this list (Ally, Marcus, Capital One 360, Synchrony, Bread), there are no caps — you earn the same rate on your entire balance.

Cost of Big Bank Savings Minimums
If you keep $500 in a big bank savings account to avoid the fee:
Scenario
Big Bank ($500, 0.01%)
HYSA ($500, 3.00%)
Interest earned
$0.05/year
$15/year
Risk of monthly fee
$5-$8 if balance dips
$0
5-year earnings (approx.)
~$0.25
~$75
If the big bank savings balance dips below the minimum for even 3 months, you lose $12-$24 in fees — wiping out years of big bank interest earnings in one bad quarter.

Most high-yield savings accounts have no minimum balance requirements, no minimum deposits, and no monthly fees. The question isn’t whether you can afford to open one — it’s whether you can afford not to, given that the same $10,000 earns about $1/year at a big bank or roughly $300-$410/year at a high-yield savings account.
