      2. What is the total carrying cost?

      3. What is the total ordering cost?

      4. What is the total annual cost at the EOQ?

Explanation / Answer

a) Total Carrying cost

Cost of carrying one unit per year    =

(cost per unit * Hurdle rate)+carrying cost per unit

($20per lens*30%)+$2.5/unit

=

8.5

Total carrying cost per year               =

(annual consumption * carrying cost per unit)

=

$44,200

b) Total ordering cost

No of orders per year                       =

Annual Consumption

Quantity ordered (EOQ)

(5200 (annual consumption) /161 (Economic Order Quantity)

32.29813665 orders per year

(32.298(orders per year) * $21.25 (per purchase order)

Total ordering cost is

686.375

c) Total annual cost at the EOQ        =      Annual carrying cost + Annual ordering cost

                                                                       =       ($44,200+$686.375)

                                                                       =      $44,886.375

Cost of carrying one unit per year    =

(cost per unit * Hurdle rate)+carrying cost per unit

($20per lens*30%)+$2.5/unit

=

8.5

Total carrying cost per year               =

(annual consumption * carrying cost per unit)

=

$44,200
