Quick context

Illustrative one-year HYSA scenario at a stated 5% APY.

How this number was calculated

The input is an effective annual percentage yield (APY). The equivalent daily rate preserves that annual yield over 365 periods:

A = P × (1 + APY)^t

where:
  P = $25,000          (principal)
  APY = 0.0500          (effective annual yield as decimal)
  n = 365                  (compounding periods per year — daily)
  t = 1                   (years)

Equivalent daily rate d = (1 + APY)^(1/365) − 1 = 0.00013368

Final balance = $25,000 × (1 + 0.00013368)^365
              = $26,250

Interest earned = $26,250 − $25,000 = $1,250
Effective APY = (1 + 0.00013368)^365 − 1 = 5%

The CFPB defines APY as a rate reflecting both the interest rate and compounding frequency over a 365-day period. This projection holds the stated APY constant and converts it to an equivalent daily rate; actual account day-count and crediting terms can differ. See the CFPB's Regulation DD APY definition.
