The payback period is the length required to recover the initial cash outlay on the project. For example if a project involves a cash outlay of Rs600000 and generates cash inflows of Rs 100000, Rs 150000 Rs 150000 and Rs 200000, in the first, second, third, and fourth years, respectively, its payback period is 4 years because the sum of cash inflows during 4 years is equal to the initial outlay divided by the annual cash inflows. For example a project which has an initial cash outlay of Rs 1000000/300000=3 1/3 years.
According to the payback criterion, the shorter the payback period, the more desirable the project. Firms using this criterion generally specify the maximum acceptable payback period. If this is n years, projects with a payback period of n years or less are deemed worthwhile and projects with a payback period exceeding n years are considered unworthy.

Evaluation
A widely used investment criterion, the payback period seems to offer the following advantages.
1. It is simple, both in concept and application. It does not use involved concepts and tedious calculations and has few hidden assumptions.
2. It is a rough and ready method for dealing with risk. It favours projects which generate substantial cash inflows in earlier years and discriminates against projects which bring substantial cash inflows in later years but not in earlier years. Now if risk tends to increase with futurity in general, this may be true the payback criterion may be helpful in weeding out risky projects.
3. Since it emphasises earlier cash inflows, it may be a sensible criterion when the firm is pressed with problems of liquidity.
