How to use it

  1. Enter the original price (Price A).
  2. Enter the new price (Price B).
  3. Click Calculate to see all four results.

What it does – The calculator takes your original price (Price A) and a new price (Price B) and instantly shows four values: the raw dollar difference, the percent change using Price A as the baseline, the symmetric percent difference based on the midpoint, and the absolute dollar gap.

Why it matters – Knowing the dollar swing helps you gauge profit or loss, while the two percentage views let you see relative impact from the seller’s and buyer’s perspectives.

How to read the results – Price Difference tells you how many dollars up or down you’re moving. Percentage Change shows the shift compared to the original price. Percentage Difference gives a balanced view that isn’t skewed by which price is higher. Absolute Difference repeats the dollar gap for quick reference.

Use the tool before negotiating a contract, updating a price list, or evaluating a discount to ensure you understand the financial impact.

Pro tips

Case study

Jane, a small-business owner, entered her product’s cost $45 and the new list price $60. The calculator showed a $15 increase, a 33.33% change from the original, and a 28.57% midpoint difference, confirming the markup was profitable before she launched the promotion.

Frequently asked questions

What is the difference between percentage change and percentage difference?
Percentage change uses the original price as the base, while percentage difference uses the average of both prices as the base.
Can I use this calculator for currency conversion?
No, it only compares two amounts in the same currency; convert first if needed.
Why does the percentage difference sometimes look larger than the change?
Because it’s measured against the midpoint, which can be smaller than the original price when prices differ greatly.
How do I interpret a negative percentage change?
It means the new price is lower than the original price, indicating a decrease.
Is the tool accurate for large numbers?
Yes, the formulas work the same for any magnitude as long as both inputs are numeric.
