Jumbo CD Calculator
Jumbo CDs require $100k or more and sometimes pay a premium. Check the extra yield — and whether the balance stays fully insured.
The jumbo premium has largely vanished
Ten years ago, $100,000 bought a meaningfully better rate. Today the best standard CDs — frequently with $500 minimums at online banks — routinely out-pay branch jumbo products. The premium shown above is the premium on your actual offer: at 0.10%, a $200,000 deposit earns an extra $200 a year, which is real money but settles nothing by itself.
The insurance line is what should settle it. That same $200,000 is fine at one bank; $300,000 is not, and no rate premium makes up for $50,000 of uninsured exposure when a bank fails.
Placing large balances without losing coverage
Three clean options. Split across institutions — two banks at $200,000 each covers $400,000 for the overhead of two logins. Use ownership categories — single, joint and IRA deposits at one bank each carry their own $250,000. Or use a brokerage: brokered CDs from a dozen issuers sit inside one account, each separately insured. The FDIC coverage calculator on this site runs the category math on your actual mix.
