Convert bird age to human years by choosing a species such as budgie, cockatiel or parrot and entering its age, or use your own lifespan or rate.

Typical pet lifespans from the Merck Veterinary Manual. Choose Custom lifespan if you know your bird’s expected lifespan.

Bird Age Formula

The following formula is used to calculate the age of a bird in human years.

BA = B × R

Variables:

  • BA is the bird’s age in human years
  • B is the bird’s actual age (in bird years)
  • R is the rate of bird to human years

To calculate the bird’s age in human years, multiply the bird’s actual age by the rate of bird to human years. The rate varies depending on the species of the bird.

How to Calculate Bird Age?

The following steps outline how to calculate the Bird Age using the formula BA = B * R.

  1. First, determine the bird’s actual age (B) in bird years.
  2. Next, determine the rate of bird to human years (R).
  3. Next, gather the formula from above = BA = B * R.
  4. Finally, calculate the Bird Age (BA).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Bird’s actual age (B) = 5 bird years

Rate of bird to human years (R) = 3
