From 4% to 5%: one percentage point or 25%?
Percentage points and percentage change answer different questions. Naming the measure prevents a small-looking rate change from being misreported.

Subtracting 4% from 5% gives one percentage point. A percentage point is the difference between two percentages expressed on the same scale. It is often the clearest way to describe a change in a survey share, fee rate or interest rate. Write “one percentage point” explicitly instead of the ambiguous phrase “up one percent.”
Relative change in that rate
Relative to the original 4%, the increase of 1 percentage point is 1/4 = 25%. Enter old value 4 and new value 5 in the percentage-change tool to verify. Both descriptions are correct: one percentage point higher and 25% higher relative to the old rate. Neither statement alone tells you the change in the final amount without knowing its base.
Apply the distinction to an amount
For a simple one-period charge on 1000, 4% is 40 and 5% is 50. The charge rises by 10, which is 25% of 40. This is a basic percentage example, not a loan repayment calculation: amortizing balances, compounding and fees change real borrowing costs. Keep the base amount, time period and rate definition identical whenever comparing two offers. This distinction matters especially when a report uses an already-percent-valued quantity as the input to another percentage calculation.
