Quick reference
1 BPS = 0.01%
10 BPS = 0.10%
25 BPS = 0.25%

100 BPS = 1.00%
Common uses
Fed rate decisions (25 or 50 BPS), mortgage rate comparisons, loan spread analysis, CD and bond yield differences, pricing adjustments.
What is a basis point?
A basis point (BPS) is a unit of measurement equal to one hundredth of one percentage point — or 0.01%. It is the standard unit used in finance to describe changes in interest rates, bond yields, equity returns, and other percentage-based metrics.
Basis points exist to eliminate ambiguity. If someone says "the rate increased by 1%", it is unclear whether the rate went from 5% to 6% (a 1 percentage point increase) or from 5% to 5.05% (a 1% relative increase). Saying it rose 100 basis points means unambiguously that it went from 5.00% to 6.00%.

How to use this basis points calculator
- BPS → %: Enter a number of basis points to convert it to a percentage.
- % → BPS: Enter a percentage to convert it to basis points.
- Rate change in BPS: Enter two rates to find how many BPS separate them.
- Apply BPS to rate: Enter a current rate and a BPS adjustment to get the new rate. Use a negative number to subtract BPS.
Common basis point values
The Federal Reserve announces rate changes in multiples of 25 BPS. A "25 basis point cut" means rates drop by 0.25 percentage points. On a $300,000 mortgage, that translates to roughly $45 per month in interest savings.
Frequently asked questions
What is one basis point?
One basis point equals 0.01%, or one hundredth of one percent. There are 100 basis points in 1%, and 10,000 basis points in 100%.
How many basis points are in 1%?
There are exactly 100 basis points in 1%. To convert percent to basis points, multiply by 100. To convert basis points to percent, divide by 100.
Why do finance professionals use basis points instead of percentages?
Basis points eliminate ambiguity. When rates are already expressed as percentages, saying something "increased 1%" is unclear — it could mean a 1 percentage point increase or a 1% relative increase. Basis points are always absolute, so "up 100 BPS" always means a 1 percentage point increase with no ambiguity.
How much is 25 basis points on a mortgage?
On a $300,000 mortgage at 6.50% over 30 years, a 25 BPS (0.25%) rate reduction to 6.25% reduces the monthly payment by approximately $48. Over the life of the loan, that saves roughly $17,000 in total interest.
What does it mean when the Fed cuts rates by 50 basis points?
A 50 BPS cut means the federal funds rate drops by 0.50 percentage points — for example, from 5.25% to 4.75%. This typically flows through to variable-rate loans, HELOCs, savings accounts, and eventually fixed mortgage rates, though timing varies.
