Since companies can issue shares and repurchase shares, you need to know the weighted average of common stock outstanding when you're figuring the earnings per share for the year. The weighted average takes into account how long each share was outstanding during the year. For example, shares issued at the start of the year will add more to the average than shares added at the end of the year. Step 1.
The average cost of cat vaccinations may be between $50 and $100 during the first year. There may be clinics with more expensive rates per vaccination. The cat will also require boosters (yearly or upon the recommendations of the vet) and these boosters may cost between $10 and $50 per year.
The average cost is $45-$55. Vaccine Boosters: Vaccine boosters are shots administered after the initial dose to keep the vaccine effective. Some of your petâs vaccinations may require boosters while others may not, but most pets require 2-4 boosters each year. The average cost for booster shots ranges between $18-$25.
