How It Works

Mode 1 — Base + %

Result = Base × (1 + % ÷ 100)

Mode 2 — % + %

Result = % 1 + % 2

Select your calculation mode — add a percentage to a base value, or sum two percentages.

Enter your values and click Calculate for an instant result.

For Base + %, you also see the amount added separately — useful for markups, discounts, and score boosts.

Example

Base: 200 + 15% = 230

Amount added = 30

30% + 45% = 75%
