Number × (1 + percent ÷ 100)

The figure after a markup: how much was added, what the total becomes, and the multiplier that does it in one step.

Markup, uplift, tax on top, an annual pay rise — all the same operation. You can do it in two steps or in one, by multiplying by the multiplier shown on its own line.

The multiplier earns its keep when uplifts stack. Two increases of 10 percent give 21 percent, not 20, because multipliers multiply: 1.1 × 1.1 = 1.21. It is the classic pricing trap.

What this calculator shows

The total after the uplift and the size of the uplift itself
The multiplier, handy for chaining several increases
The formula with your figures filled in

What to keep in mind

Percentages only add up when applied once to one base; sequential uplifts must be multiplied through their multipliers.
For VAT on top use 20 or 10 percent and the result will match the dedicated VAT calculator.

FAQs

Why doesn't +20% then −20% return the original?

Different bases. The uplift works on 1,000, the discount on 1,200. Multipliers 1.2 × 0.8 = 0.96, so you finish 4 percent below where you started.

How do I chain several increases?

Multiply the multipliers. Three rises of 5 percent give 1.05³ = 1.157, a 15.7 percent increase rather than 15.

How do I add VAT to a net price?

Multiply by 1.2 at a 20 percent rate. Extracting VAT from a gross figure is division by 1.2 — the VAT calculator shows both directions.

How is this different from percent of a number?

That page returns only the size of the increase. This one returns the new total as well.

Worked example

Markup on a wholesale price

Input: 1,000 plus 20%

Output: 1,200, with 200 added

Note: The multiplier is 1.2. Give a 20 percent discount afterwards and you land on 960, not 1,000 — the discount works off the new price.
