π The Math Behind Compound Interest
Our calculator uses the standard compound interest formula:
A = P(1 + r/n)^(nt) + PMT Γ [((1 + r/n)^(nt) - 1) / (r/n)]
Where:
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate
- n = Number of times interest compounds per year
- t = Number of years
- PMT = Regular payment amount
This ensures accurate calculations that you can trust for your financial planning.
