Percentage increase calculator

Increases are not a separate exponent or logarithm. They are the same fraction where the numerator happens to be positive. That matters because some teams maintain two spreadsheet templates; one template is enough if you teach the sign convention once.

Inflation reporting sometimes sounds like increases even when consumers dislike the outcome. Be explicit: the index rose, which is a positive percent change versus the prior index level, even if the story feels negative for households.

Use ((N − O) ÷ |O|) × 100%. When N > O, the result is positive. There is no second formula for "percent gain" unless your organization defines one; align with finance before publishing.

For rates already expressed as percents, consider percentage points for the simple gap. This article walks through both views.

1. Confirm the lower or earlier measurement is still the correct baseline, even though the story is about growth.
2. Enter baseline as original in the calculator.
3. Enter the higher measurement as new.
4. Read the positive headline and narrate the interval (YoY, QoQ, etc.).
5. Add absolute change in parentheses for executives who think in cash.

Sales climb from 1200000 to 1380000. The change is +15% versus the earlier fiscal period used as O. Mention both absolute (+180000) and relative (+15%) in the sentence so skimmers catch either framing.

Compare with neutral examples in percentage change examples and with multi-year summaries in CAGR vs percentage change when the timeline spans many years.
