**Directions:**This calculator will solve for almost any variable of the continuously compound interest formula. So, fill in all of the variables except for the 1 that you want to solve .

This calc will solve for A(final amount), P(principal), r(interest rate) or T(how many years to compound). You should be familiar with the rules of logarithms including the power rule.

Calculate

$
A = P \cdot e^{r\cdot t}
