A basis point equals 0.01 percentage point, so a 25-basis-point move equals 0.25 percentage point. Use basis points to state the absolute distance between rates or yields. Use percent change only when comparing that move with the starting rate’s size.
That distinction prevents a common reading error. If a rate climbs from 4.00% to 4.25%, it rose 25 basis points, not 25%. The relative increase is 6.25%, but that calculation answers a different question.
The terminology appears in Federal Reserve statements, Treasury yield tables, bond reports, bank offers and investment disclosures. The conversion never changes. The financial effect does, because it depends on which rate moved and what loan, account or security is attached to it.
The conversion behind most rate headlines
The U.S. Securities and Exchange Commission’s Investor.gov glossary defines one basis point as one one-hundredth of a percentage point. That gives readers a consistent unit for describing small differences without relying on ambiguous phrases such as “a fraction of a percent.”

| Basis points | Percentage points | Rate example | Common wording |
|---|---|---|---|
| 1 bp | 0.01 | 4.00% to 4.01% | One basis point |
| 10 bps | 0.10 | 4.00% to 4.10% | One-tenth of a point |
| 25 bps | 0.25 | 4.00% to 4.25% | Quarter-point move |
| 50 bps | 0.50 | 4.00% to 4.50% | Half-point move |
| 100 bps | 1.00 | 4.00% to 5.00% | One full point |
To convert basis points to percentage points, divide by 100. To convert a percentage-point difference to basis points, multiply by 100.
- 40 basis points = 0.40 percentage point
- 0.07 percentage point = 7 basis points
- 1.50 percentage points = 150 basis points
The abbreviation may appear as “bp” or “bps.” Publications differ in style, but the unit is the same.
Absolute moves and relative changes answer different questions
Basis points and percentage points describe the absolute difference between two rates. Percent change measures that difference relative to the starting value.
Suppose a yield rises from 3.75% to 4.00%. The absolute move is:
(4.00 − 3.75) × 100 = 25 basis points
The relative change is:
(4.00 − 3.75) ÷ 3.75 × 100 = 6.67%
Neither result is wrong. “Up 25 basis points” reports how far the yield moved on the percentage scale. “Up 6.67%” compares that move with the original yield.
Now change the starting point. A rise from 1.00% to 1.25% is still 25 basis points, but it is a 25% relative increase. Market coverage usually favors basis points for policy rates, yields and borrowing costs because the absolute movement remains comparable across different starting rates.
How basis points appear in a Federal Reserve decision
The Federal Open Market Committee sets a target range for the federal funds rate rather than announcing one isolated policy rate. In its July 29, 2026 statement, the committee maintained a range of 3.50% to 3.75%. The decision passed by a 9–3 vote, with three members preferring a quarter-percentage-point increase.
A quarter percentage point is 25 basis points. The existing target range was also 25 basis points wide:
(3.75 − 3.50) × 100 = 25 basis points
A 25-basis-point increase would move both ends to 3.75% and 4.00%. A decrease of the same size would produce a range of 3.25% to 3.50%.
As of September 7, 2026, the Fed’s meeting calendar lists the next scheduled FOMC meeting for September 15–16, 2026. The date matters for interpreting current coverage, but the broader rule is more durable: a Fed move changes its policy target, not every interest rate in the economy by the same number of basis points.
The federal funds rate influences other short-term rates. Mortgage rates, Treasury yields, savings yields and corporate borrowing costs also reflect market expectations, maturity, credit risk, competition and product-specific pricing. Some rates move before a Fed meeting because traders and lenders have already reacted to the expected decision.
Spreads compare two rates on the same scale
A spread is the difference between two yields or rates, normally stated in basis points. The calculation turns two separate figures into one comparison that can be followed over time.
Consider a hypothetical market screen showing a 10-year Treasury yield of 4.40% and a 2-year yield of 4.05%. The 10-year-minus-2-year spread is:
(4.40 − 4.05) × 100 = 35 basis points
If the 2-year yield were 4.55% while the 10-year remained at 4.40%, the spread would be negative 15 basis points. The negative sign indicates that the shorter maturity has the higher yield, creating an inverted section of the yield curve.
Credit spreads use the same arithmetic. A hypothetical corporate bond yielding 5.60% against a comparable Treasury yield of 4.30% has a 130-basis-point spread. As FINRA explains in its bond-spread guidance, that difference can compensate investors for credit risk and other uncertainties that do not apply in the same way to Treasury securities.
A widening spread does not identify one cause. The corporate yield may have risen, the Treasury yield may have fallen, or both may have moved. Before drawing a conclusion, check the direction of each underlying yield and whether the securities have reasonably comparable maturities.
Attach a balance to estimate the dollar effect
A basis-point figure becomes more practical once it is connected to a balance. For a rough annual interest, yield or fee estimate, use:
Balance × basis-point change ÷ 10,000
This is a screening calculation. It does not automatically reproduce a lender’s payment formula, an account’s compounding method or an investment’s future performance.
Scenario: a variable-rate balance
Assume a $300,000 balance is subject to a 25-basis-point rate increase:
$300,000 × 25 ÷ 10,000 = $750 per year
Dividing by 12 gives $62.50 a month as a simple annualized interest estimate. The actual payment change on an amortizing loan could differ because of the remaining term, reset date, principal reduction, rate caps and the contract’s payment calculation.
A savings-rate comparison
A 25-basis-point APY advantage on a steady $20,000 balance is worth approximately:
$20,000 × 25 ÷ 10,000 = $50 per year
That estimate is before taxes and does not model daily compounding or balance changes. It is still a useful reality check. A slightly higher advertised yield may add little in dollars if the account carries fees, balance requirements or inconvenient withdrawal restrictions.
An investment expense difference
On an average investment balance of $100,000, an annual fee difference of 25 basis points represents roughly:
$100,000 × 25 ÷ 10,000 = $250 per year
Recurring investment costs can have a larger long-term effect than this one-year estimate suggests because fees reduce the money left to earn potential returns. Actual costs depend on the applicable expense ratio, balance and holding period.
“Points” can refer to a different unit
A headline or sales document that says only “points” is incomplete without context.
- Basis points measure small differences between percentages, rates, yields and fee ratios.
- Percentage points express the same absolute difference in units 100 times larger.
- Index points describe changes in an index level. A 300-point Dow move is not a 300% move or a 300-basis-point move.
- Mortgage discount points are upfront charges paid in exchange for a lower offered interest rate.
According to the Consumer Financial Protection Bureau, one mortgage point equals 1% of the loan amount. One point on a $300,000 loan therefore costs $3,000.
It does not follow that one mortgage point lowers the rate by one percentage point—or by any fixed number of basis points. The rate reduction varies by lender, loan type and market conditions. Compare offers using the same number of points or credits, then examine both the cash required at closing and the cost over the period you realistically expect to keep the loan.
How to judge a rate move before acting on it
Start with the unit, then work outward. Four questions keep the calculation tied to the actual financial decision:
- Which rate changed? Identify the federal funds target range, Treasury yield, loan APR, account APY, bond spread or investment expense ratio.
- What is the comparison? Find the old rate, reference yield, benchmark or competing offer. A spread is meaningless without both sides.
- Is the product directly linked to that rate? Check whether the rate is fixed or variable and whether a benchmark, margin, reset date, cap or floor applies.
- What balance is affected? Multiply the balance by the basis-point difference and divide by 10,000 for a rough annual estimate.
Be careful with conclusions drawn from one number. A basis-point move measures distance; it does not reveal the cause, predict the next move or determine the result for a particular household.
Bond prices generally move in the opposite direction from market interest rates, especially for fixed-rate bonds, but the size of a price change depends on maturity, duration, coupon and other features. Consumer rates add another layer of contract terms and lender pricing. A bank can also change a savings APY on its own schedule rather than matching a Fed decision point for point.
When the next quarter-point headline appears, translate it to 25 basis points, identify the two rates being compared and follow the connection to the relevant loan, account or investment. If a balance is involved, convert the move into an annual dollar estimate before deciding whether it is financially significant.
