Show the math
Estimates use unrounded numbers. Displayed amounts round to cents.
What this means
A percentage increase is measured relative to the old price. Comparing a lower new price produces a negative change.
Worked example
$100 with a 10% increase becomes $110, a $10 revenue increase per unit at unchanged volume. Comparing $100 with $90 gives a 10% decrease.
How the math works
New price = old price × (1 + increase/100). Reverse change = (new price − old price)/old price × 100. Revenue change per unit = new − old.
About this estimate
No volume, demand, cost, tax or currency-change assumptions. Percentage change from zero is undefined, although the dollar change remains meaningful. Revenue per unit is not total revenue or profit.
