The formula to calculate the appraisal hike percentage (AHP) is:
\[ AHP = \frac{NA - OA}{OA} \times 100 \]
Where:
Let's say the new appraisal (NA) is $60,000 and the old appraisal (OA) is $50,000. Using the formula:
\[ AHP = \frac{60000 - 50000}{50000} \times 100 \]
We get:
\[ AHP = 20\% \]
So, the appraisal hike percentage is 20%.
