I entered $50,000 and DCU pops up with 6.17%, that's great, oh wait, it's only for up to $1K.
Also this tool appears to be missing the 2 options I personally use that beat almost all these rates.
* HMBradley Savings: 3% (a number of hoops to jump through but I've automated it all) up to $100K
* One Finance: 3% (no hoops) up to $25K
OF is my "main bank" where I keep up to $25K in that 3% savings accounts as my "semi-hot wallet" (after the checking account) and then HMB is my "cold storage" since there are some hoops to jump through to withdraw money while maintaining the rate. I have my HMB set up to always be draining via their CC (doesn't affect savings rate you must maintain to get 3%) so I can always pull $1-3K out a month on top of the 80% you can withdraw without issue (which gets ACH'd to my main bank automatically after the DD lands). This means I only "lock up" $1200/mo but the CC drains that and then some without issue. I can always ACH more into the savings account from my main bank if I'm close to the $25K limit on that savings account.
