What Is a Basis Point (BPS)? How Many Basis Points Are in 1%
By Markets & Investing DeskUpdated Nov 10, 2026
Key takeaways
- One basis point equals 0.01%, or 0.0001 in decimal form.
- 100 bps = 1%, 50 bps = 0.5%, 25 bps = 0.25%, and 10,000 bps = 100%.
- Basis points measure absolute changes in rates, yields, fees and margins. That removes the confusion between a percentage point change and a percent change.
- They apply mainly to interest rates and bond yields, but analysts also use them for index moves, fund fees, loan spreads and business margins.
A basis point (bp, bps, or “bips” when spoken) is one hundredth of one percent: 1 basis point = 0.01%, so 100 basis points = 1%. To convert basis points to a percentage, divide by 100. To convert a percentage to basis points, multiply by 100. A 50 basis point rate hike therefore means a rate that is 0.50 percentage points higher, such as a move from 4.75% to 5.25%.
Why finance uses basis points instead of percentages
Percent language becomes ambiguous when the thing being measured is already a percentage. Take the sentence “the bond’s yield was 10% before rising 5%.” It has two possible meanings:
- Absolute increase: 10% + 5 percentage points = 15%
- Relative increase: 10% × 1.05 = 10.5% (5% of 10% is 0.5 percentage points)
The two readings are far apart, and the sentence does not say which one applies. Basis points remove the doubt because one basis point is always a fixed 0.01 percentage points, whatever the starting level. The yield either rose 50 basis points (to 10.5%) or 500 basis points (to 15%). Nobody has to guess.
The same issue comes up whenever a rate changes. If a savings rate goes from 2% to 2.5%, that is a 50 bps increase, but it is also a 25% relative increase in the rate itself. Both statements are true. They answer different questions, and basis points always refer to the first one.
How to convert basis points and percentages
| Basis points | Percentage | Decimal |
|---|---|---|
| 1 | 0.01% | 0.0001 |
| 10 | 0.10% | 0.001 |
| 25 | 0.25% | 0.0025 |
| 50 | 0.50% | 0.005 |
| 75 | 0.75% | 0.0075 |
| 100 | 1% | 0.01 |
| 500 | 5% | 0.05 |
| 1,000 | 10% | 0.10 |
| 10,000 | 100% | 1 |
Basis points to percent: divide by 100. For example, 384 bps ÷ 100 = 3.84%. You can also multiply by 0.0001 to get the decimal (384 × 0.0001 = 0.0384) and then multiply by 100 for the percent form.
Percent to basis points: multiply by 100. A rise of 2.42% is 2.42 × 100 = 242 bps. You can also convert the percentage to a decimal (0.0242) and divide by 0.0001.
Basis points to dollars: multiply the amount by the basis points and by 0.0001. For example, 15 bps of $1,000,000 is $1,000,000 × 15 × 0.0001 = $1,500.
Common conversions:
- 1% is 100 basis points. Likewise, 2% is 200 bps and 4% is 400 bps.
- 400 basis points is 4%. 4,000 basis points is 40%, not 4%. Adding a zero to the basis points moves the decimal one place.
- 160 bps = 1.6%, 20 bps = 0.2%, 500 bps = 5%.
- 0.015% = 1.5 basis points. Values smaller than one basis point are written as fractions of a bp.
Examples by market
Interest rates
Central bank decisions are usually described in basis points. In May 2023, the Federal Open Market Committee raised its federal funds target by 25 basis points to a range of 5.00% to 5.25%. The federal funds rate is the rate banks charge each other for overnight lending, and it feeds through to the rates consumers pay on loans and deposits. A “50 basis point cut” is a half point lower. A “75 basis point hike” means 0.75 percentage points higher, for instance from 3.00% to 3.75%.
Bond yields and spreads
If a bond’s yield moves from 7.45% to 7.65%, it rose 20 basis points. A fall from 7.65% to 7.45% is a 20 bps decline. Credit spreads, which measure the yield gap between a corporate bond and a comparable government bond, are almost always quoted in bps. A spread of 180 bps means the corporate bond yields 1.80 percentage points more. Yield changes also move bond prices in the opposite direction; see why bond prices fall when interest rates rise.
Stocks and indexes
Basis points can also describe the percentage change in an asset’s value. A stock index that “rose 134 basis points” gained 1.34% on the day. Note the shift in meaning here. For a rate, basis points measure the change in the rate itself. For a price, they express a percent change in the price, because the price is not a percentage to begin with.
Fees and costs
Fund expense ratios, advisory fees and loan margins are often quoted in bps. A fund charging 5 bps has an expense ratio of 0.05%. On a hypothetical $10,000 holding, that works out to $5 a year. A loan priced at “the benchmark plus 250 bps” carries a rate 2.50 percentage points above that benchmark.
Business reporting
Company results often state margin changes in basis points. A gross margin that improved 500 bps went from, say, 35% to 40%, a gain of 5 percentage points. “Bps vs. LY” means the change in basis points versus last year, comparing a ratio with the same period a year earlier.
Exceptions and terms that change the meaning
Percentage points vs. percent. A basis point is always a hundredth of a percentage point, so it describes an absolute difference. If a report says a rate “rose 10%,” check whether it means 10 percentage points (1,000 bps) or a 10% relative increase. These lead to very different numbers.
Pips are not basis points. In forex, a pip is the smallest standard price increment of a currency pair. For most pairs it is 0.0001 of the quote currency (0.01 for yen pairs). It measures a change in an exchange rate, not a percentage. A one-pip move in EUR/USD is therefore not the same as a one basis point move in the pair’s value.
“Bps” outside finance. In networking, bps stands for bits per second, which is unrelated. The context tells you which one is meant.
Notation. The singular is “bp” and the plural is “bps.” Some texts use the permyriad sign (‱), meaning one part in 10,000, which equals one basis point.
FAQs
How many basis points is 1 percent?
One percent is 100 basis points. Multiply any percentage by 100 to get basis points: 0.5% is 50 bps, 2% is 200 bps.
What is 1 basis point as a fraction?
One basis point is 1/10,000 of the whole, or 1/100 of one percent. As a decimal it is 0.0001.
How much is 50 basis points in interest rates?
Fifty basis points is half a percentage point. A loan rate of 6.00% that rises 50 bps becomes 6.50%. On a hypothetical $200,000 balance, that adds about $1,000 a year in simple interest before amortization effects.
The Bottom Line
Basis points matter to anyone reading rate decisions, bond yields, fund fees or loan terms, since they state changes without the percent versus percentage point confusion. Dividing basis points by 100 gives the percentage, and multiplying a dollar amount by the basis points and 0.0001 shows the cost. When a report says a rate rose by some percent, check whether it means an absolute or relative change before acting on the number.
