The Mathematics Behind the Calculator
Our calculator uses these standard financial formulas:
Simple Interest Formula:
A = P(1 + rt)
Where:
A = Final amount
P = Principal
r = Annual interest rate (9.75% or 0.0975)
t = Time in years
Compound Interest Formula:
A = P(1 + r/n)^(nt)
Where:
A = Final amount
P = Principal
r = Annual interest rate (0.0975)
n = Number of times interest is compounded per year
t = Time in years
