Payback Period (PBP)

Payback period is a financial or capital budgeting method that computes the amount of days necessary for an investment into produce cash flows equal to the initial investment price. To put it differently, it’s that the quantity of time that it requires an investment to make enough cash to cover itself or breakeven. This time-based dimension is very important to control for assessing risk.

Definition: What is Payback Period?

Obviously the more it takes an investment to regain its initial price, the more risky the investment. Generally, an extended payback period also entails a less rewarding investment too. Consider it in handling terms. A briefer period means that they can obtain their money back earlier and invest it to something different. Therefore, maximizing the amount of investments using the similar quantity of money. A lengthier duration leaves money tied up in investments minus the capacity to reinvest capital elsewhere.

Management uses the payback period calculation to determine what projects or investments to pursue.


The simple fact period formula is figured by dividing the price of the undertaking or investment from its own yearly cash inflows.

Payback Period Formula

As you can see, with this revival interval calculator you a percent as a response. Multiply this percentage by 365 and you may arrive in the amount of days it’ll take for your own undertaking or investment to make enough money to cover itself.

Since a few company endeavors don’t last an entire year and others are ongoing, you can supplement this equation for any income period. For example, you could use monthly, semi-annual, or even two-year cash inflow periods. The cash inflows should be consistent with the length of the investment.


Let’s take a look at an example. Assume Jim’s Body Shop has $10,000 to invest in new equipment. Jim can either buy a new buffing wheel that will save labor hours and his crew from hand polishing the car finishes or he can buy a bigger sandblaster that will be able to fit all his car parts in it thus getting rid of the need to outsource his sandblasting.

Jim estimates that the new buffing wheel will save 10 labor hours a week. Jim currently plays his finishing personnel $25 per hour. Thus, at $250 a week, the buffer will have generated enough income (cash savings) to pay for itself in 40 weeks. Here is how to calculate the payback period for Jim’s Shop.

How to Calculate Payback Period

On the other hand, Jim could buy the sandblaster and save $100 a week from without having to outsource his sandblasting.


Management uses the cash payback period equation to see how quickly they will obtain the company’s money back from an investment-the quicker the better. In Jim’s example, he has the option of buying equipment that will be paid back 40 weeks or 100 weeks. It’s obvious that he should choose the 40-week investment because after he earns his money back from the buffer, he can reinvest it in the sandblaster.

Longer payback periods are not only more risky than shorter ones, but they are also more uncertain. The longer it takes for an investment to earn cash inflows, the more likely it is that the investment will not breakeven or make a benefit. 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.

Keep in mind that the cash payback period principle does not work with all types of investments like assets and bonds equally as well as it does with capital investments. The main argument for this is it doesn’t even take into consideration the time value of money. Theoretically, longer money stays at investment, the less it’s worth. Cash today is worth more than cash tomorrow. To be able to account for the time value of cash, the discounted payback period has to be utilized to dismiss the cash inflows of their job in the correct rate of interest.
