Payback Period PBP Formula Example Calculation Method

payback formula

The fractional period is the ratio of the last opposite cash flow and cash flow in the year after. That’s why we utilize the ABS function to calculate the fractional period. Return on Investment (ROI) is the annual return you receive on investment, and it measures the efficiency of the investment, compared to its cost. A payback period, on the other hand, is the time it takes to recover the cost of an investment. A payback period refers to the time it takes to earn back the cost of an investment.

What Is the Formula for Payback Period in Excel?

For this reason, the payback period may return a positive figure, while the discounted payback period returns a negative figure. The payback period is the amount of time accounting services for startups for a project to break even in cash collections using nominal dollars. Company C is planning to undertake a project requiring initial investment of $105 million.

Payback Period Formula – Averaging Method

The rate of return can be positive or negative, thus, resulting in a gain or a loss for a specific investment. Ultimately, the aim of project investment is to achieve profitability beyond that in which it turns breakeven. Based on this example, project B presents a better investment opportunity.

Payback Period Formula

Cumulative net cash flow is the sum of inflows to date, minus the initial outflow. A below 1 ratio (PI can’t be a negative number) suggests that the investment doesn’t create enough or as much value in order to be considered. The index is a good indicator of whether a project creates or destroys company value. The DPP can be calculated in Excel or by using a discounted payback calculator.

  • I hope we covered all possible areas regarding the payback period with uneven cash flows.
  • One of the biggest advantages of the payback period method is its simplicity.
  • Thus, at $250 a week, the buffer will have generated enough income (cash savings) to pay for itself in 40 weeks.
  • Using the subtraction method, one starts by subtracting individual annual cash flows from the initial investment amount, and then does the division.
  • Any investments with longer payback periods are generally not as enticing.
  • For a short time payback period, you need to have a higher cash inflow in the initial stage.

The reinvestment rate refers to the company’s weighted average cost of capital or WACC. The WACC is the function of the weighted average of the cost of equity and the cost of debt. Conversely, if the IRR falls below the required rate of return that the company or the investor seeks, then other more economically viable alternatives should be considered. In the arsenal of corporate finance tools for capital budgeting, it’s worth seeing how it compares to other capital budgeting methods such as NPV, IRR, modified IRR, and profitability index. Just like the basic payback period, its modified counterpart calculates the time required to retrieve the invested funds. Depending on the nature of the investment and the time horizon, it may take a while for the project to return the invested capital, if at all.

Payback Period

It should be used with, but not limited to, the mentioned cash flow metrics, NPV and RoR, to build a more exhaustive picture of the viability of a project, its downside risks, and trade-offs. The TVM provides more sophisticated and detailed investment information than the simple time frame of the return on investment which is disregarded by this tool. The payback period doesn’t take into consideration other ways an investment might bring value, such as partnerships or brand awareness. This can result in investors overlooking the long-term benefits of the investment since they’re too focused on short-term ROI. If earnings will continue to increase, a longer payback period might be acceptable. If earnings might decrease after a certain number of years, the investment may not be a good idea even if it breaks even quickly.

What Is the Discounted Payback Period?

Any particular project or investment can have a short or long payback period. The payback period can apply to personal investments such as solar panels or property maintenance, or investments in equipment or other assets that a company might consider acquiring. Often an investment that requires a large amount of capital upfront generates steady or increasing returns over time, although there is also some risk that the returns won’t turn out as hoped or predicted. Our first method is based on using the conventional formula for calculating the payback period with uneven cash flow. In this method, we will calculate step-by-step, after that we will get the payback period with uneven cash flow.
