## Discounted Payback Period

The discounted payback period formula is used to calculate the length of time to recoup an investment based on the investment's discounted cash flows. By discounting each individual cash flow, the discounted payback period formula takes into consideration the time value of money.

## $$\frac{\mathrm{Log}\left(\frac{1}{1-\frac{r}{c}}\right)}{\mathrm{Log}(1+r)}$$

Here,o=initial investment,r=rate,c=periodic cash flow
