Many managers and investors thus prefer to use NPV as a tool for making investment decisions. The NPV is the difference between the present value of cash coming in and the current value of cash going out over a period of time. Unlike other methods of capital budgeting, the payback period ignores the time value of money (TVM). This is the idea that money is worth more today than the same amount in the future because of the earning potential of the present money.
An implicit assumption in the use of payback period is that returns to the investment continue after the payback period. Payback period does not specify any required comparison to other investments or even to not making an investment. Without considering the time value of money, it is difficult or impossible to determine which project is worth considering.
Understanding the Payback Period
Each company will internally have its own set of standards for the timing criteria related to accepting (or declining) a project, but the industry that the company operates within also plays a critical role.

- The NPV is the difference between the present value of cash coming in and the current value of cash going out over a period of time.
- The purchase of machine would be desirable if it promises a payback period of 5 years or less.
- The term is also widely used in other types of investment areas, often with respect to energy efficiency technologies, maintenance, upgrades, or other changes.
- Thus, maximizing the number of investments using the same amount of cash.
- The shorter the payback period, the more attractive the investment would be, because this means it would take less time to break even.
It can help to use other metrics in financial decision making such as DCF analysis, or the internal rate of return (IRR), which is the discount rate that makes the NPV of all cash flows of an investment equal to zero. For instance, a $2,000 http://www.flashdaweb.com/2008/03/dolphin-installation-screencast/ investment at the start of the first year that returns $1,500 after the first year and $500 at the end of the second year has a two-year payback period. As a rule of thumb, the shorter the payback period, the better for an investment.

Since most capital expansions and investments are based on estimates and future projections, there’s no real certainty as to what will happen to the income in the future. For instance, Jim’s buffer could break in 20 weeks and need repairs requiring even further investment costs. That’s why a shorter payback period is always preferred over a longer one. The more quickly the company can receive its initial cost in cash, the more acceptable and preferred the investment becomes. The discounted payback period is the number of years it takes to pay back the initial investment after discounting cash flows.
Most capital budgeting formulas, such as net present value (NPV), internal rate of return (IRR), and discounted cash flow, consider the TVM. So if you pay an investor tomorrow, it must include an opportunity cost. The shorter the discounted payback period, the quicker the project generates cash inflows and breaks even. While comparing two mutually exclusive projects, the one with the shorter discounted payback period should be accepted. Initially the project involves a cash outflow, arising from the original investment of £500,000 and some project losses in Year 1 of £50,000.
Discounted payback period formula
On the other hand, negative cash flow such as the payment for expenses, rent, and taxes indicate a decrease in liquid assets. Oftentimes, cash flow is conveyed as a net of the sum total of both positive and negative cash flows during a period, as is done for the calculator. The study of cash flow provides a general indication of solvency; generally, having adequate cash reserves is a positive sign of financial health for an individual or organization. Acting as a simple risk analysis, the is easy to understand. It gives a quick overview of how quickly you can expect to recover your initial investment. The payback period also facilitates side-by-side analysis of two competing projects.
- One project might be paid back faster, but – in the long run – that doesn’t necessarily make it more profitable than the second.
- This type of analysis allows firms to compare alternative investment opportunities and decide on a project that returns its investment in the shortest time if that criteria is important to them.
- This is because they factor in the time value of money, working opportunity cost into the formula for a more detailed and accurate assessment.

- Calculating the payback period for the potential investment is essential.
Payback period is the amount of time it takes to break even on an investment. The appropriate timeframe for an investment will vary depending on the type of project or investment and the expectations of those undertaking it. Investors may use payback in conjunction with return on investment (ROI) to determine whether or not to invest or enter a trade. Corporations and business managers also use the payback period to evaluate the relative favorability of potential projects in conjunction with tools like IRR or NPV.
Second, we must subtract the discounted cash flows from the initial cost figure in order to obtain the discounted payback period. Once we’ve calculated the discounted cash flows for each period of the project, we can subtract them from http://www.advlab.ru/articles/article52.htm the initial cost figure until we arrive at zero. To determine how to calculate payback period in practice, you simply divide the initial cash outlay of a project by the amount of net cash inflow that the project generates each year.
