The value obtained using the discounted payback period calculator will be closer to reality, although undoubtedly more pessimistic. When deciding on which project to undertake, a company or investor wants to know when their investment will pay off, i.e., when the project’s cash flows cover the project’s costs. The discounted payback period of 7.27 years is longer than the 5 years as calculated by the regular payback period because the time value of money is factored in. The discounted payback period (DPP) is a success measure of investments and projects.

Cash Flow Projections and DPP Calculation

Discounted payback period refers to time needed to recoup your original investment. In other words, it’s the amount of time it would take for your cumulative cash flows to equal your initial investment. The discounted payback period involves using discounted cash inflows rather than regular cash inflows. It involves the cash flows when they occurred and the rate of return in the market. As mentioned above, the payback period is the amount of time it takes to recover the initial costs of an investment.

  1. The numbers used in this example are stemming from the case study introduced in our project business case article where you will also find the results of the simple payback period method.
  2. Discounted payback period will usually be greater than regular payback period.
  3. The concept is the same as the payback period except for the cash flow used in the calculation is the present value.
  4. Suppose a company is considering whether to approve or reject a proposed project.
  5. The next step involves summing these discounted cash flows until the initial investment is recovered.

Next, assuming the project starts with a large cash outflow, or investment to begin the project, the future discounted cash inflows are netted against the initial investment outflow. The discounted payback period process is applied to each additional period’s cash inflow to find the point at which the inflows equal the outflows. At this point, the project’s initial cost has been paid off, with the payback period being reduced to zero. The shorter a discounted payback period is means the sooner a project or investment will generate cash flows to cover the initial cost.

The payback period is the time it takes an investment to break even (generate enough cash flows to cover the initial cost). Certain businesses have a payback cutoff which is essential to consider when proceeding with investment projects. In addition to the first two flaws, the business owner also has to guess at the interest rate or cost of capital. Consequently, it is not the best method to use when choosing an investment project. That said, this third flaw of the discounted payback period can be dismissed if the weighted average cost of capital is used as the rate at which to discount the cash flows.

Payback Period Formula

Forecasted future cash flows are discounted backward in time to determine a present value estimate, which is evaluated to conclude whether an investment is worthwhile. In DCF analysis, the weighted average cost of capital (WACC) is the discount rate used to compute the present value of future cash flows. WACC general ledger vs trial balance is the calculation of a firm’s cost of capital, where each category of capital, such as equity or bonds, is proportionately weighted. For more detailed cash flow analysis, WACC is usually used in place of discount rate because it is a more accurate measurement of the financial opportunity cost of investments.

Second, we must subtract the discounted cash flows from the initial cost figure to calculate. So, once we calculate the discounted cash flows for each project period, we can subtract those discounted cash flows from the initial cost until we reach zero. The discounted payback period is a measureof how long it takes until the cumulated discounted net cash flows offset theinitial investment in an asset or a project. In other words, DPP is used tocalculate the period in which the initial investment is paid back. The basic method of the discounted payback period is taking the future estimated cash flows of a project and discounting them to the present value.

It’s important to consider other financial metrics and factors specific to the investment before making a decision. The time value of money is a fundamental concept in finance that suggests that a dollar in hand today is worth more than a dollar promised in the future. This is because money available today can be invested and earn a return, hence growing over time. In other words, the purchasing power of money decreases over time due to factors such as inflation or interest rates. For example, if solar panels cost $5,000 to install and the savings are $100 each month, it would take 4.2 years to reach the payback period. In most cases, this is a pretty good payback period as experts say it can take as much as years for residential homeowners in the United States to break even on their investment.

WACC can be used in place of discount rate for either of the calculations. The discounted payback period is the number of years it takes to pay back the initial investment after discounting cash flows. In Excel, create a cell for the discounted rate and columns for the year, cash flows, the present value of the cash flows, and the cumulative cash flow balance.

Because of the opportunity cost of receiving cash earlier and the ability to earn a return on those funds, a dollar today is worth more than a dollar received tomorrow. Discounted payback period process is a helpful metric to assess whether or not an investment is worth pursuing.

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. One of the disadvantages of discounted payback period analysis is that it ignores the cash flows after the payback period. Thus, it cannot tell a corporate manager or investor how the investment will perform afterward and how much value it will add in total.

The company would use this calculation to decide if the investment in the new machine is worth the cost based on when they would recover the initial investment considering the time value of money. Discounted payback period will usually be greater than regular payback period. Investments with higher cash flows toward the end of their lives will have greater discounting.

The time it takes for the present value of future cash flows to equal the initial cost of a project indicates when the project or investment will break even. The calculationtherefore requires the discounting of the cash flows using an interest ordiscount rate. The discounted payback period has a similar purpose as the payback period which is to determine how long it takes until an initial investment is amortized through the cash flows generated by this asset. It is a useful way to work out how long it takes to get your capital back from the cash flows.It shows the number of years you will need to get that money back based on present returns. Each present value cash flow is calculated and then added together.The result is the discounted payback period or DPP.

For example, three projects can have the same payback period with varying break-even points due to the varying flows of cash each project generates. The initial outflow of cash flows is worth more right now, given the opportunity cost of capital, and the cash flows generated in the future are worth less the further out they extend. First, the time value of money is not considered when you calculate the payback period. In other words, no matter for which year you receive a cash flow, it is given the same weight as the first year.

The discounted payback period determines the payback period using the time value of money. However, one common criticism of the simple payback period metric is that the time value of money is neglected. Once you have this information, you can use the following formula to calculate discounted payback period. The payback period will help the company to use their fund more effective, it recommends to invest in a project which has the shortest payback period.

In addition, the potential returns and estimated payback time of alternative projects the company could pursue instead can also be an influential determinant in the decision (i.e. opportunity costs). Conceptually, the payback period is the amount of time between the date of the initial investment (i.e., project cost) and the date when the break-even point has been reached. The Discounted Payback Period does not consider cash flows that occur after the payback period and might involve subjective decisions in setting the discount rate. Unlike the traditional Payback Period, the Discounted Payback Period accounts for the time value of money by discounting future cash flows to their present value. For this reason, sometimes, the regular payback period is used early on as a simpler metric when determining what projects to take on. Unlike the regular payback period, the discounted payback period metric considers this depreciation of your money.

From another perspective, the payback period is when an investment breaks even from an accounting standpoint. Discounted payback, in contrast, includes the time value of money, so it is viewed from a financial perspective. The following tables contain the cash flowforecasts of each of these options. Read through for the definition and formulaof the DPP, 2 examples as well as a discounted payback period calculator. In such situations, we will first take the difference between the year-end cash flow and the initial cost left to reduce. Next, we divide the number by the year-end cash flow in order to get the percentage of the time period left over after the project has been paid back.

A discounted payback period is used as one part of a capital budgeting analysis to determine which projects should be taken on by a company. A discounted payback period is used when a more accurate measurement of the return of a project is required. This discounted payback period is more accurate than a standard payback period because it takes into account the time value of money. 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 the initial cost figure until we arrive at zero.

As you can see, the required rate of return is lower for the second project. The situation gets a bit more complicated if you’d like to consider the time value of money formula (see time value of money calculator). After all, your $100,000 will not be worth the same after ten years; in fact, it will be worth a lot less. Every year, your money will depreciate by a certain percentage, called the discount rate. For example, where a project with higher return has a longer payback period thus higher risk and an alternate project having low risk but also lower return.
