Basis Point Calculator — bp to Percentage Converter
A basis point (bp) is 1/100th of one percent — the standard unit for quoting interest rates, yield spreads and fee changes in finance. Enter the number of basis points and a reference value to instantly convert to a percentage, decimal and the exact currency change.

How does this calculator work?
1 basis point = 0.01% = 0.0001. To convert: percentage = bp ÷ 100; decimal = bp ÷ 10 000; currency change = principal × (bp ÷ 10 000). Used in finance to quote interest rates and spreads unambiguously — 100 bp always equals exactly 1 percentage point.
Formula
How this is calculated
A basis point equals 0.01 percentage points (not 0.01% of the rate — it is an absolute unit). So if a central bank raises rates by 25 bp, that is exactly 0.25 percentage points, regardless of the starting level. The conversion is simply: percentage = bp ÷ 100, and decimal = bp ÷ 10 000.
To find the currency impact, multiply the principal (loan balance, bond face value, portfolio size, etc.) by the decimal equivalent. A 50 bp move on a €1 000 000 bond position equals €500 — a figure traders need instantly.
Basis points avoid the ambiguity of saying "the rate rose by 10%" (which could mean it went from 2% to 12%, or from 2% to 2.2%). They are used universally in interest rate swaps, mortgage spreads, credit default swaps and central-bank policy statements.
Frequently asked questions
100 basis points equal 1 percentage point. So 50 bp = 0.50%, 25 bp = 0.25%, and 1 bp = 0.01%. Divide basis points by 100 to get the percentage, or multiply the percentage by 100 to get basis points.
Basis points remove ambiguity. Saying "the yield rose by 10%" is unclear — 10% of 2% is 0.20%, but 10 basis points is always exactly 0.10 percentage points. They also make small differences (like 5 bp vs 7 bp) easy to compare and communicate precisely.
Asset managers commonly quote annual fees in basis points: a 50 bp (0.50%) expense ratio is standard for active funds; passive ETFs often charge 3–20 bp. Mortgage spreads over government bonds are quoted in basis points, and central banks adjust policy rates in 25 or 50 bp increments.
