Prices fluctuate due to supply and demand, production costs, and inflation. Calculating the exact percentage helps you decide if a product is still worth buying or if a service fee hike is reasonable.

Inflation: Raw materials cost more, so final products cost more.
Demand: High popularity (like concert tickets) drives prices up.
Shrinkflation: Price stays the same, but package size gets smaller (effectively a price increase per unit).

How to Calculate Markups

Markup Formula:

((Selling Price - Cost Price) / Cost Price) * 100

This calculator works perfectly for markups too. Enter your Cost as "Original Price" and Selling Price as "New Price" to see your markup percentage.

Real World Examples

Gas Prices: If gas goes from $3.50 to $4.00, that is a 14.3% increase.
Streaming Service: If a subscription goes from $14.99 to $17.99, that is a 20% hike.
Groceries: If eggs go from $2.00 to $4.00, that is a massive 100% increase (doubling).

Pricing FAQ

How do you calculate percentage increase in price?

Subtract the Original Price from the New Price. Divide that number by the Original Price. Then multiply by 100.

What is the difference between markup and margin?

Markup is percentage of cost (added on top). Margin is percentage of the final sales price that is profit. They are often confused but calculated differently.

Is inflation the same as price increase?

Inflation is the general rise of prices across an entire economy. A price increase is specific to one item. However, businesses often raise prices *because* of inflation.

How do I calculate a price drop?

Use the same calculator! If New Price is lower than Old Price, the result will be negative, indicating a discount or price drop percentage.
