📐 Formula Behind CD Earnings

The calculator uses the standard compound interest formula:

iniCopyEditA = P × (1 + r/n)^(n×t) 

Where:

• P = principal deposit
• r = annual interest rate (decimal form, e.g., 0.0415)
• n = compounding periods per year
• t = time in years (e.g. 9 months = 0.75 years)
• A = future value (principal + earned interest)

Interest Earned = A − P
