A basis point (bp, plural bps, often pronounced “bips”) is one-hundredth of one percentage point. One basis point equals 0.01%, or 0.0001 as a decimal, and 100 basis points make 1%. Finance uses the unit to state interest rates, yields, spreads, fees and small percentage changes without the ambiguity that ordinary percent language can create.

When a central bank “raises rates by 25 bps,” the policy rate goes up by 0.25 percentage points. If the target was 4.00%, it becomes 4.25%. It does not mean the rate grew by 25% of itself.

Key takeaways

• 1 basis point = 0.01% = 0.0001, fixed by definition.
• Divide basis points by 100 to get percent; multiply percent by 100 to get basis points.
• Basis points state absolute changes or differences between rates, which avoids confusion with relative percent changes.
• They are used for policy rates, loan pricing over benchmarks such as SOFR, bond yields, credit spreads and fund expense ratios.
• The price value of a basis point (PVBP or DV01) converts a one-basis-point yield move into a dollar change in a bond’s price.

What a Basis Point Measures

A basis point is a unit of percentage, not a unit of money or price. On its own, “20 bps” is just 0.20%; it becomes meaningful when attached to a yield, a rate, a fee, a spread or a percentage change in a price.

That makes basis points useful in two situations:

1. Changes in a rate. A bond yield moving from 5.00% to 5.20% rose 20 basis points. A dividend yield moving from 3.0% to 3.3% rose 30 basis points.
2. Differences between rates. A bond yielding 4.3% pays 30 basis points more than a bond yielding 4.0%.

The unit is sometimes written with the permyriad sign (‱), meaning “per ten thousand,” because one basis point is one part in 10,000. In practice, financial writing almost always uses “bp” or “bps.”

Converting Basis Points, Percentages and Decimals

The formulas:

• Basis points to percent: percent = bps ÷ 100. Example: 350 bps ÷ 100 = 3.5%.
• Percent to basis points: bps = percent × 100. Example: 0.05% × 100 = 5 bps.
• Basis points to decimal: decimal = bps ÷ 10,000. Example: 6 bps ÷ 10,000 = 0.0006.
• Decimal to percent: multiply by 100. Percent to decimal: divide by 100.

A common slip is mixing up “0.05” and “0.05%.” The number 0.05 as a decimal is 5%, or 500 basis points. The figure 0.05% is 5 basis points. The 100-fold gap between the two shows why stating the unit matters.

Basis Points vs. Percentage Points vs. Percent Change

A percentage point is the arithmetic difference between two percentages. Going from 10% to 11% is a one-percentage-point rise, which is 100 basis points.

A percent change is relative. Going from 10% to 11% is a 10% increase in the rate, because the rise of 1 is 10% of the starting value of 10.

Now consider the sentence “a 10% interest rate increased by 10%.” It could mean:

• the rate rose by 10% of itself: 10% × 1.10 = 11%, or
• the rate rose by 10 percentage points: 10% + 10% = 20%.

Those readings differ by a factor of ten in the size of the move. In basis points the meaning is unambiguous: a 100 bp increase takes the rate to 11%, and a 1,000 bp increase takes it to 20%. That is why traders, lenders and analysts quote rate moves in basis points.

Basis points can also express relative changes in prices, which is a different use. If a stock falls from $200 to $199, the $1 drop is 0.5% of the starting price, or 50 basis points. Context tells you which use is meant: a “50 bp move in the 10-year yield” is a change in the yield’s level, while a “50 bp move in the stock” is a relative price change.

Where Basis Points Are Used

Central Bank Policy Rates

Policy rate decisions are typically announced and reported in basis points, as in the 25 bp example above. When a central bank sets a target range, such as the Federal Reserve’s federal funds range, a 25 bp move shifts both the lower and upper bounds by 0.25 percentage points.

Loan and Deposit Pricing

Many variable-rate loans are priced as a benchmark plus a margin stated in basis points. A business loan quoted at “SOFR + 50 bps” carries a rate 0.50 percentage points above the Secured Overnight Financing Rate. If SOFR resets higher, the loan rate follows; the 50 bp margin stays fixed under the contract.

Rate changes reach households too. After a policy increase, savings rates and payments on variable-rate debt such as adjustable-rate mortgages, many credit cards and some personal loans may rise, depending on each product’s terms. A fixed-rate loan does not change.

Bond Yields

Bond markets quote yield changes almost exclusively in basis points because daily moves are often small. “The 10-year yield rose 8 bps” is more precise than “rose slightly” and shorter than “rose 0.08 percentage points.” The same unit describes the gap between yields at different maturities, such as the spread between 2-year and 10-year Treasury yields.

Credit Spreads

A credit spread is the extra yield a bond pays over a comparable benchmark, usually a government bond of similar maturity. If a corporate bond yields 3% and a comparable government bond yields 2%, the spread is 1 percentage point, or 100 bps.

The spread reflects the compensation investors demand for the issuer’s credit risk. A widening from 100 bps to 150 bps can follow from a weaker financial position at the issuer or a broader shift in market conditions. Because a bond’s fixed coupon cannot change, a higher required yield means a lower price, so widening spreads push bond prices down and narrowing spreads push them up, all else equal.

Fund Fees

Expense ratios for mutual funds and ETFs are often compared in basis points. A fund with an annual expense ratio of 0.15% costs 15 bps per year. An analyst might say a 0.35% fund is “10 bps cheaper” than a 0.45% fund. Advisory fees and some trading costs are also quoted this way.

Risk Management and Stress Testing

Risk managers express rate scenarios in basis points. A stress test might ask what a 200 bp jump in rates does to a portfolio’s value, then rerun the model with slightly larger or smaller shocks to test sensitivity. Moves in equity prices, exchange rates and commodity prices can also be expressed in basis points to compare volatility across markets in a common unit.

Price Value of a Basis Point (PVBP or DV01)

The price value of a basis point measures how much a bond’s price changes, in currency terms, when its yield changes by one basis point. It is also called DV01, short for “dollar value of 01” (a 0.01% move). It is a measure of interest rate risk closely related to duration.

Duration expresses the percentage price change for a change in yield. PVBP is a special case of dollar duration that uses a one-basis-point move instead of a 100-basis-point move. A common approximation is:

PVBP ≈ Modified duration × Bond price × 0.0001

Because one basis point is so small, the price change is about the same whether yields rise or fall by that amount, so the sign of the move barely affects PVBP.

Hypothetical example. Assume a bond priced at $1,000 with a modified duration of 7.

• PVBP ≈ 7 × $1,000 × 0.0001 = $0.70.
• A 1 bp rise in yield lowers the price by about $0.70; a 1 bp fall raises it by about $0.70.
• For a position with $10 million in market value and the same duration, PVBP ≈ 7 × $10,000,000 × 0.0001 = $7,000 per basis point.

The approximation is linear. For larger moves, such as a 100 bp or 200 bp shock, the actual price change departs from PVBP × number of basis points because the price-yield relationship is curved (convexity). PVBP is most reliable for small moves, which is how traders use it: to size hedges and compare the rate sensitivity of different positions on a like-for-like basis.

What Basis Points Mean in Dollars

A basis point has no dollar value until you apply it to an amount. The general formula is:

Dollar effect = Amount × (bps ÷ 10,000)

Hypothetical example: a loan rate change. Assume a $300,000 variable-rate balance and a 25 bp rate increase.

• Extra annual interest ≈ $300,000 × 0.0025 = $750.
• This uses simple annual interest on the full balance. On an amortizing mortgage, the actual payment change depends on the remaining term and how the lender recalculates, and the balance declines over time.

Hypothetical example: fund fees over time. Assume $100,000 invested for 20 years with a 6% annual gross return, comparing a fund charging 0.45% with one charging 0.35%. Treating the fee as a straight deduction from the yearly return:

• 0.45% fund: net 5.55% per year, about $294,550 after 20 years.
• 0.35% fund: net 5.65% per year, about $300,180 after 20 years.
• Difference: roughly $5,600 from a 10 bp gap in annual cost.

The example ignores taxes, trading costs and return variability. A fee is a recurring percentage of assets, so a small basis-point difference compounds with the balance.

Basis Points vs. Pips, Ticks and Index Points

Several trading units are easy to confuse with basis points.

Pips. In forex, a pip is the standard price increment of a currency pair, usually 0.0001 for most pairs and 0.01 for pairs quoted against the Japanese yen. A pip on EUR/USD is the same decimal as a basis point, but it measures a change in the exchange rate itself, not a percentage. If EUR/USD trades at 1.1000, a one-pip move to 1.1001 is a change of 0.0001 ÷ 1.1000, about 0.91 bps. The two units only coincide when the price is exactly 1.0000. Forex traders sometimes say “bips” loosely, but pip counts and basis points are different measurements.

Ticks. A tick is the minimum price increment an exchange allows for a contract. Some interest rate futures have tick sizes tied to fractions of a basis point, but a tick is defined by contract specifications, not by the basis-point definition.

Index points. A “200-point move in the Dow” means the index level changed by 200, not 200 basis points. To express it in basis points, divide the point change by the starting level and multiply by 10,000. With the index at a hypothetical 40,000, a 200-point move is 0.5%, or 50 bps. The same logic applies to the S&P 500 or any other index.

Everyday reporting quotes stock prices in dollars and cents, but analysts and traders use basis points for stock moves when they need precision, such as measuring execution costs or a portfolio’s performance gap to its benchmark.

Limitations of Basis Points

• No scale on their own. A 25 bp change means very different things on a $5,000 balance and a $5 million portfolio.
• Same size, different significance. A 25 bp move matters more relative to a 1% rate than to a 10% rate. Basis points state the absolute change; the relative change, if it matters, needs a separate calculation.
• Context is required. “50 bps” can describe a rate change, a spread, a fee or a relative price move. A figure without its reference point (above what, on what, over what period) is incomplete.
• Not a measure of risk-adjusted performance. A fund beating its benchmark by 30 bps tells you the size of the outperformance, not whether it took extra risk to get there. Measures such as alpha and the Sharpe ratio address that question.

Where the Term Comes From

The name comes from “basis,” a term in bond and money markets for the difference, or spread, between two interest rates or prices. Since spreads between rates are often a fraction of a percentage point, quoting them in hundredths of a percent became standard, and “basis point” came to mean that hundredth.

FAQs

The Bottom Line

Anyone reading rate decisions, loan quotes, bond yields or fund fees benefits from knowing that basis points measure absolute changes in a rate. Converting them is simple, but a figure only gains dollar meaning when applied to a balance, and it needs its reference point to be clear. Small gaps add up: a 10 bp fee difference on $100,000 over 20 years came to roughly $5,600.
