What a basis point is
A basis point (bp or bps) is one hundredth of a percent: 1 bps = 0.01%, so 100 bps = 1%. To convert, divide basis points by 100 for the percentage: 50 bps ÷ 100 = 0.50%. On a $10,000 amount, 50 bps is 0.50% = $50. Basis points avoid the ambiguity of saying "a 1% increase" when you mean a rate moving from 5% to 6% versus rising by 1% of 5%. Basis points are just hundredths of a percent, and the percentage calculator handles the plain-percent version.
How to use this calculator
Enter the number of basis points to see the equivalent percentage and decimal. Optionally enter an amount to get the dollar impact — useful for fees, interest rate changes, or expense ratios. Leave amount at 0 to just convert bps to percent. When you need the change between two rates rather than the gap in points, use the percentage change calculator.
Basis point conversion table
Common values:
| Basis points | Percent | On $10,000 |
|---|---|---|
| 1 bps | 0.01% | $1 |
| 25 bps | 0.25% | $25 |
| 50 bps | 0.50% | $50 |
| 100 bps | 1.00% | $100 |
| 250 bps | 2.50% | $250 |
Where basis points are used
Finance uses bps for precision: central banks raise rates by "25 basis points," fund fees are quoted as expense ratios (e.g. 50 bps = 0.50% a year), and bond yields move in bps. A small-sounding 25 bps fee on a large balance adds up — on $1,000,000 it's $2,500 a year.
Why bps beat percentages for changes
Saying a rate "went up 1%" is ambiguous — from 5% to 6% (a 100 bps move) or to 5.05% (a 1% relative increase)? Basis points remove the confusion: "up 100 bps" always means a one-percentage-point rise. To see how a rate change affects savings or loans, pair this with the APY calculator or loan calculator.

Frequently asked questions
- How do I convert basis points to a percentage?
- Divide the basis points by 100. 50 bps ÷ 100 = 0.50%. And 100 bps equals 1%.
- What is 50 basis points?
- 0.50%, or 0.005 as a decimal. On a $10,000 amount that's $50.
- How many basis points are in 1 percent?
- 100. One percent equals 100 basis points, and 1 basis point is 0.01%.
- Why use basis points instead of percentages?
- They remove ambiguity when talking about rate changes. "Up 100 bps" clearly means a one-percentage-point rise, unlike "up 1%."
- How much is 25 bps on a large balance?
- 25 bps is 0.25%. On $1,000,000 that's $2,500 — which is why small fee differences matter on big amounts.
