Your AI pulls current HYSA and Money Market benchmarks to measure your CD's yield. You get a direct comparison showing exactly how much extra you're earning or leaving on the table.

The results you get

Once you provide the CD details, your AI generates these specific outcomes.

YIELD

Calculated CD return

The AI determines the exact interest you'll earn based on the principal, rate, and term you provide.

BENCHMARK
