The formula for the payback method is simplistic: Divide the cash outlay (which is assumed to occur entirely at the beginning of the project) by the amount of net cash inflow generated by the project per year (which is assumed to be the same in every year).
What is payback method formula?
To calculate the payback period you can use the mathematical formula: Payback Period = Initial investment / Cash flow per year For example, you have invested Rs 1,00,000 with an annual payback of Rs 20,000. Payback Period = 1,00,000/20,000 = 5 years. Payback Period = 3 + (2,00,000 – 1,85,000) / 40,000 = 3.375 years.
Is payback method the same as payback period?
To calculate a more exact payback period: payback period = amount to be invested / estimated annual net cash flow. The payback method also ignores the cash flows beyond the payback period; thus, it ignores the long-term profitability of a project.

How is the payback period calculated in net cash flow?
Payback period is usually expressed in years. Start by calculating Net Cash Flow for each year, then accumulate by year until Cumulative Cash Flow is a positive number: that year is the payback year. Some businesses modified this method by adding the time value of money to get the discounted payback period.
Which is longer the payback period or the maximum?
The payback period for this project is 3.375 years which is longer than the maximum desired payback period of the management (3 years). The investment in this project is therefore not desirable.
When does the payback period for a project start?
