This percent increase calculator shows how much a value grew from a starting number to a new number—as a percentage and absolute change. Enter original and new values for price hikes, growth metrics, or grade improvements.

Percent increase is always relative to the starting amount. A $10 jump from $50 is 20%, but the same $10 from $200 is only 5%.

Use the same units for both values—mixing dollars and cents causes errors.

How to use this tool

Enter the starting value and the new value. The calculator returns absolute change and percent increase relative to the original.

Worked example

Example: a price rising from $80 to $100 is a $20 increase—equal to a 25% increase over the original value.

When to use this

  • Analyzing price or rent increases.
  • Reporting KPI or revenue growth.
  • Checking homework or spreadsheet math.

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.
  • Confusing percentage points with percent change.
  • Forgetting to convert fractions to percentages.

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.

FAQ

Frequently asked questions

What is the percent increase formula?

Percent increase = [(New − Original) ÷ Original] × 100.

Can the result be negative?

If the new value is lower, you get a negative percent change—a decrease. Use the percent decrease variant for labeling.

Does order of values matter?

Yes. First value is the baseline (original); second is the new value.
