Details: Calculating wage increase percentage is essential for salary negotiations, performance reviews, inflation adjustments, and understanding real wage growth after accounting for cost of living changes.
Tips: Enter both old and new wage amounts in the same currency per hour format. Ensure values are positive numbers. The calculator will automatically compute the percentage increase.
Q1: What is considered a good wage increase percentage?
A: A typical annual wage increase ranges from 2-5% for cost of living adjustments, while promotions or exceptional performance may warrant 5-15% increases.
Q2: How does wage increase differ from raise amount?
A: Raise amount is the absolute difference in currency, while percentage increase shows the relative change, making it easier to compare across different salary levels.
Q3: Can this calculator handle wage decreases?
A: Yes, if the new wage is lower than the old wage, the calculator will show a negative percentage, indicating a wage decrease.
