# Compound interest calculator

Compound Interest is calculated on the initial payment and also on the interest of previous periods.

Example: Suppose you give \$100 to a bank which pays you 10% compound interest at the end of every year. After one year you will have \$100 + 10% = \$110, and after two years you will have \$110 + 10% = \$121.

example 2:
What will a deposit of $\color{blue}{\$3500}$at$\color{blue}{10\,\%}$compounded$\color{blue}{\text{monthly}}$be worth if left in the bank for$\color{blue}{8 \, \text{years}}$? example 3: How much money would you need to deposit today at$\color{blue}{8\% \, \text{annual}}$interest compounded$\color{blue}{\text{monthly}}$to have$\color{blue}{\$1200}$ in the account after $\color{blue}{12 \, \text{years}} \, \text{?}$
example 4:
Find the present value of $\color{blue}{\$1000}$to be received at the end of$\color{blue}{2 \, \text{years}}$at a$\color{blue}{12\%}$nominal annual interest rate compounded$\color{blue}{\text{quarterly}}$. example 5: What annual interest rate is implied if you lend someone$\color{blue}{\$1700}$ and are repaid $\color{blue}{\$ 1910}$in$\color{blue}{\text{two years}}$? example 6: Suppose that a savings account is compounded$\color{blue}{\text{monthly}}$with a principal of$\color{blue}{\$1350}$. After $\color{blue}{8 \, \text{months}}$, the amount increased to $\color{blue}{\$ 1424}$. What was the per annum interest rate? example 7: How long does it take for$\color{blue}{\$4300}$ to grow into $\color{blue}{\$6720}$at$\color{blue}{9\,\%}$compounded$\color{blue}{\text{quarterly}}\$?
