Original valueThe starting number or baseline. It must not be zero for the standard percentage-increase formula.New valueThe later, higher or comparison value.Optional comparison increase (%)Used for the what-if note and printable worksheet comparison.

Live result25% increase20 change ÷ 80 baseline · multiplier 1.25× · 10% what-if = 88

Formula used

Increase amount = new value − original value. Percentage increase = (increase amount ÷ original value) × 100. Growth multiplier = new value ÷ original value.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Resulting answer

25% increase

20 change ÷ 80 baseline · multiplier 1.25× · 10% what-if = 88

Answer: 25% increase
Live support: 20 change ÷ 80 baseline · multiplier 1.25× · 10% what-if = 88

Assumptions used

What this answer assumes

Best for growth, before-and-after comparisons, school worksheets, quote changes, performance reports and audit notes where the baseline must stay visible.

The original value is the baseline and must be greater than zero for the standard percentage-increase formula.
The calculator reports an increase when the new value is above the original value; if the new value is lower, it reports the signed decrease clearly in the result support text.
The optional comparison increase is a what-if planning row only; it does not change the entered new value.
Rounding is for display. Keep more decimal places for audits, spreadsheets, experiments, finance records or formal reporting.

Master’s Tip

How to use the result well

Master’s Tip: name the baseline in every report. “Increased by 25%” is only meaningful when readers know the original value was 80, not 100 or some later adjusted base.

25% increase20 change ÷ 80 baseline · multiplier 1.25× · 10% what-if = 88

Inputs

Original value: 80
New value: 100
Optional comparison increase: 10 %

Method

Increase amount = new value − original value. Percentage increase = (increase amount ÷ original value) × 100. Growth multiplier = new value ÷ original value.

If the original value is 80 and the new value is 100, the increase is 100 − 80 = 20. Percentage increase = 20 ÷ 80 × 100 = 25%. The growth multiplier is 100 ÷ 80 = 1.25×.

Assumptions

The original value is the baseline and must be greater than zero for the standard percentage-increase formula.
The calculator reports an increase when the new value is above the original value; if the new value is lower, it reports the signed decrease clearly in the result support text.
The optional comparison increase is a what-if planning row only; it does not change the entered new value.
