Have heard this term so many times, and decided to know it today
I am glad I did, because it is so easy a concept, and according to me sounds very powerful and scholarly (when you mention it)
So when a change in a parameter we measure is from 5% to 6%, it would typically be a 20% increase in the normal sense. But using basis points, all arithmetic can be avoided to conveniently say 100 basis point = 1% percentage point.
1 basis point = (1/100)*(1%).
So 100 basis points = 100*(1/100)*(1%) = 1% percentage point
Neat!!
So if interest rates have been raised by 25 basis points = 0.25% percentage points => if the interest was 2.5%, now it will be 2.75%
Ah, finally I feel enlightened on this term.

You are 10,000 basis points correct! In other words, 100% ha ha ha
