High-Yield Savings Account Comparison

Rates last checked: August 19, 2026

A High-Yield Savings Account (HYSA) is one of the safest places to grow your group's pooled savings while you work toward your investment goal. Below is a side-by-side look at popular options so you can pick the account that fits your group best.

APYs and terms change often — always confirm current rates on the bank's site before opening an account. Some links on this page may be affiliate links, meaning PoolUp may earn a small commission at no extra cost to you. This does not influence the accounts we list.

Up to 3.80% APY
Min. balance

3.80% APY only with qualifying direct deposit (or $5,000+ in qualifying deposits every 30 days). Without it, savings earns a much lower base rate. A SoFi Plus membership boost is also part of the advertised top rate — most members will not automatically get 3.80%.

Pros
  • Top-tier rate if you route direct deposit here
  • Combined checking + savings with vaults
  • Expanded FDIC coverage via partner bank network
Cons
  • Headline APY requires direct deposit or large recurring deposits
  • Base rate without qualifying is well below other banks here

  • Unlimited ATM rebates at the highest tier
Cons
  • Lower rate than the online banks here
  • Tiered — top rate is not automatic
