Example Data Table

Scenario	Old Rate (%)	New Rate (%)	Change (bps)	Principal	Approximate Impact
Corporate Bond Yield	5.20	5.45	25	$100,000	$250.00
Mortgage Rate Review	6.10	5.85	-25	$250,000	-$625.00
Treasury Move	4.00	4.75	75	$500,000	$3,750.00
Fund Pricing Change	—	—	10	$1,000,000	$1,000.00

Formula Used

1. Basis points from percent difference
Basis Points = (New Rate − Old Rate) × 100

2. Percent from basis points
Percent = Basis Points ÷ 100

3. Decimal rate from basis points
Decimal Rate = Basis Points ÷ 10,000

4. Amount impact from basis points
Value Impact = Principal × (Basis Points ÷ 10,000)

These formulas help compare yield movement, loan pricing, spread changes, and value sensitivity using a standard finance unit.

Frequently Asked Questions

1. What is a basis point?

A basis point is one hundredth of one percent. It equals 0.01%. Finance teams use it to describe small rate changes clearly and avoid confusion.

2. How many basis points are in 1%?

There are 100 basis points in 1.00%. So 0.25% equals 25 basis points, and 2.50% equals 250 basis points.

3. Why use basis points instead of percent?

Basis points make small changes easier to read. Saying rates rose 15 basis points is clearer than saying they rose 0.15%.

4. Can this calculator compare two rates?

Yes. Use Rate Change mode, enter the old and new rates, and the tool returns absolute change, basis points, and relative movement.

5. How is value impact estimated?

The tool multiplies principal by the decimal rate equivalent of the basis point move. This gives an estimated change in value for the amount entered.

6. Can I convert basis points to a decimal rate?

Yes. The calculator shows decimal form too. Divide basis points by 10,000 to convert the move into decimal rate format.

7. Does a negative basis point move mean rates fell?

Yes. A negative result means the new rate is lower than the old rate. That signals a decrease in yield or pricing rate.

8. When should I download CSV or PDF?

Use CSV for spreadsheets and quick records. Use PDF when sharing a clean summary with clients, teams, or audit files.
