Payback Period vs. Discounted Payback Period: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 7, 2024
Payback Period is time taken to recover the cost of an investment. Discounted Payback Period is time taken to recover the cost of an investment, considering the time value of money.
Key Differences
The payback period is a financial metric used to determine the time it takes for an investment to generate enough cash flows to recover the initial investment cost. The discounted payback period, meanwhile, adjusts these cash flows for the time value of money, reflecting the present value of future cash flows.
In calculating the payback period, all cash flows are considered equally, regardless of when they occur. In contrast, the discounted payback period discounts each cash flow to its present value, accounting for the cost of capital or a specific discount rate.
The payback period offers a simple and quick estimation of investment risk, focusing solely on the time needed to break even. The discounted payback period provides a more accurate and financially sound measure, as it includes the concept of the time value of money.
The payback period is easy to compute and understand, it ignores the value of money over time and cash flows after the payback period. The discounted payback period addresses these limitations by considering the diminishing value of future cash flows and providing a more comprehensive analysis.
The payback period can be misleading for long-term investments due to its neglect of the time value of money. The discounted payback period, however, gives a realistic view of the investment’s profitability by considering the reduced value of future cash flows.
