# Simple interest

## Inputs

• principal amount
• rate of interest (annual) [%]
• number of years

## Outputs

• future value (or end-of-period value or terminal value)

## Neuron type

Best algorithm has been found - locked

## Patterns

Pattern Input Output
1.
 principal amount: 1000 rate of interest (annual) [%]: 10 number of years: 2
 future value (or end-of-period value or terminal value): 1200
2.
 principal amount: 750 rate of interest (annual) [%]: 15 number of years: 5
 future value (or end-of-period value or terminal value): 1312.5

## Applicable neurons

• Plus (x + y)
• Multiple (x × y)
• 1
• Percentage (X% / 100)
