Percentage points (vs percent)

An absolute difference between two percentages. A rate moving from 5% to 7% is a 2 percentage point change — but a 40% increase in percent terms.

“Percentage point” and “percent” are not the same thing, and the difference matters in finance writing. A percentage point is the absolute arithmetic difference between two rates. A percent (or basis points) describes a relative change.

If your loan rate moves from 5% to 7%: • In percentage point terms, that's +2 percentage points (or +200 basis points). • In percent terms, that's a 40% increase ((7-5)/5 = 0.40).

Rate forecasts and Fed announcements use percentage points (or basis points) because the relative-change framing is misleading. A “25 percent rate cut” could mean Fed Funds dropping from 4% to 3% (one full point) OR from 4% to 3.99% (one basis point) depending on interpretation. The unambiguous version: “25 basis points” = 0.25 percentage points.

“Basis points” (often abbreviated “bp” or “bps”) is just percentage points multiplied by 100 — used in finance when sub-percentage-point precision matters. 100 basis points = 1 percentage point.

PayoffMath angle. Most rate-coverage gets the units wrong: a 'rate cut' headline usually means percentage points, not percent. The distinction matters for prepayment math — a half-point rate cut on a $50k HELOC saves a different amount than a 'half-percent' cut, which would mean almost nothing.

Why it matters. Lender ads, Fed announcements, and even some servicer letters mix the two terms. Reading them as the same thing routinely produces savings estimates that are wrong by an order of magnitude.

Common mistake. Translating 'the Fed cut 25 basis points' as 'my mortgage rate is going to drop 0.25%.' Prime-linked products (HELOCs, cards) move with Fed Funds; 30-year mortgages track the 10-year Treasury and often barely react to a Fed move.

Try the heloc payoff calculator model what a 25- or 50-basis-point Prime cut does to the payoff date on a variable-rate HELOC.

Worked example

Example: the Fed cuts rates “by 50 basis points.” That's 0.5 percentage points — Fed Funds drops from 4.50% to 4.00%. NOT a 50% rate cut. Mortgage rates that follow typically drop a similar 30-60 basis points (not the same as the Fed cut, since mortgages track the 10-year Treasury, not Fed Funds directly).
