How to Calculate Stock Growth Rate (5 Steps)

Divide the final value of the stock by the initial value of the stock. For example, if the stock started off being worth $120 and is now worth $145, you would divide $145 by $120 to get 1.20833.
Divide 1 by the number of years the growth occurred over. For example, if it took three years to go form $120 to $145, you would divide 1 by 3 to get 0.3333.
Raise the result from Step 1 to the result from Step 2. In this example, you would raise 1.20833 to the 0.3333 power to get 1.0651
Take away 1 from the Step 3 result. In this example, you would take away 1 from 1.0651 to get 0.0651.
Convert the result from Step 4 from a decimal to a percentage by multiplying by 100 to find the compound annual growth rate. Finishing the example, you would multiply 0.0651 by 100 to find the compound annual growth rate to be 6.51 percent.

How to Stock Your Farm Pond

Check the depth of the farm pond using a fishing rod with a heavyweight sinker to reach the bottom 8 feet and a bobber. Eight feet is a minimum depth for an optimum fish environment.
Remove any overabundance of weeds and aquatic vegetation that might prevent fishing as growth becomes more prolific. Check for holes in the dam from muskrats or other rodents and repair before stocking.
Stock channel catfish fish in the fall first. Stock less than 50 channel catfish fish per acre.
Stock bluegill and minnows or any other feeder fish in the fall. Stock bass and predator fish in the spring so they can feed off the feeder fish, bluegill and fathead minnow beams after breeding takes place in the spring.
Check for winterkill. Count how many bass and other predator fish die so you can replace them when spring arrives to maintain a balance of predator/prey fish.
Watch for summerkill. Replenish any fish that die out during the summer or you harvest through fishing so you can maintain an ideal balanced environment.
