How much does $10,000 earn at 5% APY with daily compounding for 10 years?

$10,000 at a fixed 5% effective annual yield grows to $16,289 over 10 years, earning $6,289. Because APY already reflects compounding, its equivalent daily rate reproduces 5% APY rather than increasing it again.

For effective APY a = 0.0500, the equivalent daily rate is d = (1 + a)^(1/365) − 1 = 0.00013368. Then A = P × (1 + d)^(365 × t) = P × (1 + a)^t. For P = $10,000 and t = 10, the projected balance is $16,289.

Is 5% APY realistic in 2026?

Compare 5% with the current provider APY and account terms. A HYSA rate is variable, while a CD rate generally applies for its stated term; review the live disclosure before committing cash.

Does daily compounding actually matter vs monthly?

This scenario starts with a quoted APY, which already reflects the account rate and compounding frequency. Converting it to an equivalent daily rate preserves the same annual yield; it does not add a second compounding uplift. To compare frequencies, start with the same nominal APR and calculate the effective APY for each frequency.

Quick context

Illustrative ten-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 = $10,000          (principal)
  APY = 0.0500          (effective annual yield as decimal)
  n = 365                  (compounding periods per year — daily)
  t = 10                   (years)

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

Final balance = $10,000 × (1 + 0.00013368)^3650
              = $16,289

Interest earned = $16,289 − $10,000 = $6,289
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.
