# Basis Point Calculator

Convert basis points to percentages and calculate the dollar impact on loans and investments. 1 basis point = 0.01%.

## What this calculates

Quickly convert basis points to percentages and see the actual dollar impact on your loan, mortgage, or investment portfolio. One basis point equals 0.01%, so 50 basis points is 0.50%.

## Inputs

- **Basis Points (bps)** — min 0 — Number of basis points. 1 bp = 0.01%.
- **Principal Amount** ($) — min 0 — The loan, investment, or portfolio value to apply the basis points to.
- **Direction** — options: Rate Increase, Rate Decrease — Whether basis points represent an increase or decrease.

## Outputs

- **Percentage Equivalent** — formatted as percentage — The basis points expressed as a percentage.
- **Decimal Equivalent** — The basis points expressed as a decimal.
- **Dollar Impact (Annual)** — formatted as currency — Annual dollar change from this basis point shift on your principal.
- **Dollar Impact (Monthly)** — formatted as currency — Monthly dollar change from this basis point shift.

## Details

A basis point (bp or bps) is one hundredth of a percentage point. The finance industry uses basis points instead of percentages to avoid ambiguity. If someone says a rate "increased by 1%," that could mean from 5% to 6% (100 bps) or from 5% to 5.05% (5 bps). Saying "100 basis points" removes all confusion.

The dollar impact adds up fast on large amounts. A 25 basis point rate increase on a $500,000 mortgage adds $1,250 per year in interest, or about $104 per month. On a $10 million bond portfolio, that same 25 bps represents $25,000 annually.

The Federal Reserve typically moves its benchmark rate in increments of 25 basis points. When you hear "the Fed raised rates by a quarter point," that is 25 basis points. During aggressive tightening cycles, the Fed has moved by 50 or even 75 basis points at a single meeting, and the impact ripples through mortgage rates, savings yields, and bond prices.

## Frequently Asked Questions

**Q: How many basis points are in 1 percent?**

A: There are 100 basis points in 1 percentage point. So 0.25% equals 25 basis points, 0.50% equals 50 basis points, and 1.00% equals 100 basis points. To convert basis points to a percentage, divide by 100. To convert a percentage to basis points, multiply by 100.

**Q: Why do finance professionals use basis points instead of percentages?**

A: Basis points eliminate ambiguity. If a bond yield goes from 3% to 3.5%, saying it "rose 0.5%" could be confused with a 0.5% relative increase (which would be 3.015%). Saying it "rose 50 basis points" is unambiguous. This precision matters when billions of dollars are at stake.

**Q: How do basis points affect my mortgage payment?**

A: Every 25 basis points (0.25%) on a $300,000 30-year fixed mortgage changes your monthly payment by roughly $45. Over the life of the loan, that 25 bps difference adds up to about $16,000 in total interest. Even small basis point differences are worth shopping for when you are borrowing large amounts.
