Compound Interest Formulas
Future value: A
Initial deposit: C
Annual rate of invested: r
Number of years inverted: t
Number of times compounded per year: n
1. General Compound Interest Formula
A = C( 1 +)nt
2. Simplified Compound Interest Formula
If interest is compounded once per year, than the previous formula simplifies to:
A = C(1 + r)t.
3. Continuous Compound Interest
If interest is compound continually (n → ∞), than
A = Cert .
