What is the Regular payback period is defined as?

The regular payback period is defined as the time it takes for an investment to generate enough cash flow to recover its initial cost. It is calculated by summing the cash inflows until they equal the initial investment amount. This metric helps investors assess the risk and liquidity of an investment, as shorter payback periods typically indicate quicker returns. However, it does not account for the time value of money or cash flows received after the payback period.
