How do I calculate percentage-point difference?

Subtract the starting rate from the ending rate using their percentage values. From 4% to 5%, 5 − 4 = 1 percentage point. Reversing the order gives -1 percentage point.

Is five percentage points the same as 5%?

No. A rate rising from 10% to 15% gains 5 percentage points, but its relative increase is (15 − 10) ÷ 10 × 100 = 50%. The pp figure is the plain subtraction.

Can the starting rate be zero?

Yes. From 0% to 5% is a 5-point rise. Relative percentage change from zero is undefined because its formula divides by the starting rate.

Does this compare statistical significance or business quality?

No. It subtracts the two supplied rates. A confidence interval, sample sizes or a rule for interpreting a margin would require additional information and a different calculation.

Enter the starting and ending rates as percentages to find their signed arithmetic gap. From 4% to 5% is +1 percentage point, abbreviated pp. The relative increase is 25%, and the symmetric percentage difference is 22.2222222222%; those use different denominators and separate questions in the calculator.

What is the percentage-point change from 4% to 5%?1 ppThis is the signed arithmetic gap between two rates, not their relative percentage change or symmetric percentage difference.

Change and difference are not the same thing. Going from 80 to 100 is a 25% increase, measured against where you started. But the percentage difference between 80 and 100 is 22.22%, because that one divides by the average of the two. Change has a direction; difference does not. Reports and spreadsheets mix these up constantly, which is why both are here as separate questions.

Margin and markup are the same profit over two different divisors. Something that costs 40 and sells for 100 earns 60 either way, but the margin divides that by the selling price and is 60%, while the markup divides it by the cost and is 150%. Margin can never pass 100%; markup has no ceiling. The profit margin question above reports both, each beside the number it divided by.
