Frequently asked questions
How do I calculate a percentage change?
Subtract the starting value from the final value, divide by the starting value and multiply by 100. Going from 50 to 65 is a 30% increase.
How do I find the price before an increase?
Divide the final price by (1 + increase). If a price rose 25% to 100, the original was 100 / 1.25 = 80.
