What is the amount of money increase divided by the original amount?

The amount of money increase divided by the original amount is a way to calculate the percentage increase. It is expressed as: ((\text{New Amount} - \text{Original Amount}) / \text{Original Amount}). This ratio can then be multiplied by 100 to convert it into a percentage. For example, if the original amount is $100 and the increase is $20, the calculation would be ((20 / 100) \times 100 = 20%).
