© The McGraw-Hill Companies, Inc., Formula for Evaluating a Robot Investment Where P = Payback period in years I = Total capital investment required in robot and accessories L = Annual labor costs replaced by the robot (wage and benefit costs per worker times the number of shifts per day) E = Annual maintenance cost for the robot Z = Annual depreciation q = Fractional speedup (or slowdown) factor (in decimals). Example: If robot produces 150 % of what the normal worker is capable of doing, the fractional speedup factor is 1.5. The payback formula for an investment in robots is:

© The McGraw-Hill Companies, Inc., Example of Evaluating a Robot Investment Suppose a company wants to buy a robot. The bank wants to know what the payback period is before they will lend them the $120,000 the robot will cost. You have determined that the robot will replace one worker per shift, for a one shift operation. The annual savings per worker is $35,000. The annual maintenance cost for the robot is estimated at $5,000, with an annual depreciation of $12,000. The estimated productivity of the robot over the typical worker is 110%. What is the payback period of this robot? P = I = 120,000 =1.47years L–E+q(L + Z) 35,000–5, (35,000+12,000)
