How much is 1300 worth after
10 years
using an annual interest rate of 5%
compounded annually?

## Calculate Accumulated Balance

A = B(1 + i)n
where A = accumulated balance
B = opening balance
i = Annually interest rate
and n = number of periods

## Plugging in our values

A = 1300(1 + 0.05)10
A = 1300(1.05)10
A = 1300(1.6288946267774)
A = 2,117.56

## How much interest was earned?

Interest Earned = Accum. Value - Start Balance

## Plug in our values

Interest Earned = 2,117.56 - 1,300.00
Interest Earned = 817.56

A = 2,117.56
Interest Earned = 817.56

A = 2,117.56
Interest Earned = 817.56
