Percentage Increase Calculator

Percentage increase measures growth relative to where you started:

% increase = (New value − Old value) ÷ Old value × 100

Dividing by the old value is what makes it a percentage of the original — a ₹50 rise on a ₹100 base is 50%, but the same ₹50 rise on a ₹1,000 base is only 5%.

A product's price rises from ₹100 to ₹150:

• Absolute change = 150 − 100 = ₹50
• % increase = (150 − 100) ÷ 100 × 100 = 50%

The price grew by half of its original value.

Percentage increase is the headline number — use it when comparing growth across different starting points, since it normalises for scale. Absolute change is the raw difference in the original units; keep it in view because a huge percentage on a tiny base can be misleading (going from 1 to 3 customers is +200%, but it's still only 2 customers).

If the result is negative, the value actually decreased — switch to the percentage decrease calculator for that framing.
