How this number was calculated
Daily compound interest formula with n = 365 compounding periods per year:
A = P × (1 + r/n)^(n × t)
where:
P = $50,000 (principal)
r = 0.0400 (annual rate as decimal)
n = 365 (compounding periods per year — daily)
t = 10 (years)
Daily rate = r/n = 0.000110 (0.01100% per day)
Final balance = $50,000 × (1 + 0.000110)^3650
= $74,590
Interest earned = $74,590 − $50,000 = $24,590
Effective APY = (1 + 0.000110)^365 − 1 = 4.081%Same closed-form math used by Investor.gov (SEC) and the Federal Reserve. Want to run a different combination? Open the full calculator.
