Calculates investment growth with compound interest over time.
The compound interest calculator applies the standard formula P·(1+r/n)^(n·t) to show how an investment or debt grows when interest is earned on previously accumulated interest.
A = P × (1 + r/n)^(n·t) Interest earned = A − P
$5,000 at 6% compounded quarterly for 10 years: A = 5000 × (1 + 0.06/4)^(40) = 5000 × 1.8140 ≈ $9,070. Interest earned ≈ $4,070.
