This percentage decrease calculator shows the percent drop from a starting value to a lower value—plus the absolute difference. Use it for price cuts, budget reductions, and performance declines.

Percent decrease is always relative to the starting amount, not the ending amount.

How to use this tool

Enter the original (higher) value and the new (lower) value. The calculator returns absolute change and percent decrease.

Worked example

Example: revenue falling from $50,000 to $42,500 is a $7,500 decrease—15% decrease from the original.

When to use this

  • Reporting cost savings as a percentage.
  • Analyzing stock or metric drawdowns.
  • Homework and spreadsheet checks.

Common examples

  • What is 15% of 200? → 30 (discount or tip on a subtotal).
  • 45 is what percent of 180? → 25% (test score or completion rate).
  • Price rose from $80 to $100 → 25% percent increase.
  • Sale price $89 with 30% off → $62.30 before tax.
  • Team finished 18 of 24 tasks → 75% completion for status report.

Common mistakes

  • Dividing by the new value instead of the original.
  • Labeling a decrease as negative increase without clarity.
  • Mixing percentage points with percent change.

How it works

Supports five percentage modes: find X% of Y, find what percent X is of Y, percent change between two values, increase Y by X%, and decrease Y by X%.

Limitations

Handles common percentage math only. Rounding differences may appear when chaining multiple percentage operations.
