Actually in common usage (as in newspapers, radio and TV news stories)
people very often do say, incorrectly, "increased by 3%".in the case you
give there is little difference (3% of 95% is 2.85%), but an increase of
3% from 10% to 13% is a lot different from an increase of 10%.

In finance when talking about interest etc. the term used is "percentage
points" or often just "points" ("the stock is down 3 points from
yesterday").
As a former mathematician the situation is often even worse. "Inflation
is up by 1%" is talking about a second derivative, the rate of increase
of a rate of increase, but politicians often use it as a figure in its
own right. Several countries have claimed things like a decsrease in
the unemployment rate -- the actual number of people unemployed was
still rising, but the rate at which they were becoming unemployed was
reducing -- as a decrease "in unemployment".
