Step-by-step explanation:
Upfront cost = $1,000,000
Yearly benefits = $400,000
The payback period is the time that a business takes to repay the amount investment. That is, the time it takes to break even.

![t=(\$1,000,000)/(\$400,000) \\t=2.5\ years](https://img.qammunity.org/2020/formulas/business/college/kepueh9y85lecvctthqo2yjcalw6xgqhn5.png)
