The Tiny Unit That Moves Trillions
Basis points are the fundamental unit of finance for expressing rate changes. 1 bp = 0.01% = 0.0001 — and that tiny difference can mean thousands of dollars on mortgages, bonds, and portfolios.
Did our AI summary help? Let us know.
50 bps fee on $1M portfolio = $5,000/yr; over 30yr at 7% return = $170K lost. Fed typically moves in 25 or 50 bp increments — each move reprices mortgages and credit. Bond yields and credit spreads are quoted in bps; DV01 measures dollar impact of 1 bp. Always compare expense ratios in bps — a 10 bp difference compounds dramatically over decades.

Why: Basis points eliminate ambiguity in rate discussions. Saying 'rates up 1%' could mean 5% to 6% (100 bps) or 5% to 5.05% (5 bps). The Fed, bond traders, and mortgage lenders all quote in bps. A 25 bp mortgage rate drop saves ~$18K over 30 years on a $300K loan.

💡 Money Facts
1 bp = 0.01% = 0.0001 in decimal form. 100 bps = 1%.
— CFA Institute
Fed raised rates by 75 bps multiple times in 2022 — each move = 0.75%.
— Federal Reserve
50 bps fee on $100K = $500/yr; over 30yr at 7% = $17K lost.
— SIFMA
25 bp mortgage drop from 7% to 6.75% saves ~$50/mo on $300K = $18K over 30yr.
— CFPB
On $1M portfolio: 1bp = $100/yr, 10bps = $1,000/yr, 100bps = $10,000/yr.

📐 What Is a Basis Point?
A basis point (bp) = 1/100th of 1% = 0.01%. Finance uses basis points to avoid ambiguity: saying "rates increased by 1%" could mean from 5% to 6% (100 bps) or from 5% to 5.05% (5 bps). The Fed's famous 75 bp hikes in 2022 meant 0.75% increases each time. On large portfolios, basis points matter enormously: a 50 bp fee on a $1M portfolio = $5,000/yr. Over 30 years at 7% return, that 50 bp fee costs $170K in lost growth! Warren Buffett famously said: "Watch the pennies and the dollars take care of themselves" — in finance, watch the basis points.

📊 Basis Points to Percentage
Divide basis points by 100. 25 bps = 0.25%, 75 bps = 0.75%, 100 bps = 1%. To convert percent to bps, multiply by 100.
| Basis Points | % Equivalent | Decimal |
|---|---|---|
| 1 bp | 0.01% | 0.0001 |
| 25 bp | 0.25% | 0.0025 |
| 50 bp | 0.50% | 0.005 |
| 100 bp | 1.00% | 0.01 |
💡 Why Use Basis Points?
Basis points eliminate ambiguity. "Rates up 1%" is unclear; "rates up 100 bps" is precise. The Fed, bond traders, and mortgage lenders all quote in bps.
🏦 Fed Rate in Basis Points
The Federal Reserve moves in 25 or 50 bp increments. In 2022, the Fed raised rates by 75 bps multiple times — each move = 0.75%. A 25 bp hike reprices mortgages, car loans, and credit cards.
📈 Basis Points in Bond Yields
Bond yields move in basis points. A Treasury yield moving 15 bps from 4.50% to 4.65% is precise. Credit spreads (corporate vs Treasury) are often 100–200 bps. DV01 = dollar value of 1 bp yield change.
🏠 Basis Points in Mortgage Rates
A 25 bp drop from 7.00% to 6.75% saves ~$50/mo on a $300K loan = $18K over 30 years. Lenders quote spreads over Treasury yields in bps. Each 25 bp change significantly impacts monthly payments.
📋 Key Takeaways
- • 1 bp = 0.01% = 0.0001
- • 100 bps = 1%
- • Fed moves in 25 or 50 bp increments
- • 50 bp fee on $1M = $5,000/yr; over 30yr at 7% = $170K lost
- • In fixed income, always quote in bps — never percentages
