Basis Point Calculator

Convert basis points to percentages and calculate the dollar impact of rate changes.

Conversion:
1 basis point = 0.01% = 0.0001
100 basis points = 1%
Interest Impact = Principal × (bps/10000) × Years

What is a Basis Point?

A basis point (bp or bps) is one hundredth of a percentage point (0.01%). Financial professionals use basis points to express small rate changes precisely: "The Fed raised rates by 25 basis points" means a 0.25% increase.

Why Basis Points Matter

On a $500,000 mortgage, a 25 bps rate change equals $1,250/year in interest. On a $1 billion bond portfolio, 1 basis point = $100,000/year. The larger the principal, the more each basis point matters.
