Step 1
Begin by determining the salvage value of the motorcycle. You can determined this by taking 15 percent of the Kelly Blue Book value of the motorcycle (see Resources). Also determine the value of the motorcycle when purchased.
-
Step 2
Calculate the estimated useful life of the motorcycle by subtracting the number of years since its production from eight (8), the typical lifespan of a motorcycle.
-
Step 3
Plug the values into the following formula: Cost of motorcycle -- Salvage Value / Estimated Useful Life = Annual depreciation value. Example: $12,500 - $1,875 / 8 = $1,328 per year.
-
Step 4
Multiply the value you calculated in Step 2 by the number of years since you purchased the motorcycle. Then subtract that value from the purchase value of the motorcycle to get the depreciated value. Example: $12,500 - (5 years x $1,328) = $5,860.
