  • Perpetual vs. Periodic Counting

    • Perpetual inventory updates the quantities continuously and periodic inventory updates the amount only at specific times, such as year end.
    • Periodic inventory is when information about amount and availability of a product is updated only periodically.
    • Most companies who use periodic inventory perform this at year-end.
    • In earlier periods, non-continuous or periodic inventory systems were more prevalent.
    • Many small businesses still only have a periodic system of inventory.

  • Calculating the Payback Period

    • To calculate a more exact payback period: Payback Period = Amount to be initially invested / Estimated Annual Net Cash Inflow.
    • Payback period in capital budgeting refers to the period of time required for the return on an investment to "repay" the sum of the original investment.
    • Payback period is usually expressed in years.
    • The modified payback period algorithm may be applied then.
    • To be more detailed, the payback period would be: 4 + 2/7 = 4.29 year.
