Basis Points

A basis point (abbreviated bps, pronounced "bips") is a unit of measurement equal to one one-hundredth of a percentage point, or 0.01%. In numerical terms, 1 basis point = 0.0001 in decimal form. The scale is straightforward: 100 basis points equal 1 full percentage point, 50 basis points equal 0.50%, and 25 basis points equal 0.25%.

Commercial lenders, underwriters, and capital markets professionals use basis points rather than percentages to eliminate ambiguity. When someone says a rate "increased by 2%," it is unclear whether the rate moved from 5% to 7% (a 2 percentage point increase) or from 5% to 5.10% (a 2% relative increase). Saying the rate "increased by 200 basis points" removes all doubt: the rate moved exactly 2 percentage points. This precision is critical when even small differences represent significant dollar amounts on large commercial loans.

Basis points appear throughout commercial finance. Interest rate changes from the Federal Reserve are reported in basis points. Lending spreads, the margin a lender adds above a reference rate like the prime rate or SOFR, are quoted in basis points. Origination fees, guarantee fees, and other transaction costs are frequently expressed this way. For example, an SBA guarantee fee might be described as 50 basis points (0.50%) of the guaranteed portion.

The conversion math is simple. To convert basis points to a percentage, divide by 100. To convert a percentage to basis points, multiply by 100. A spread of 275 basis points equals 2.75%. An origination fee of 1.5% equals 150 basis points. On a $2,000,000 commercial loan, each basis point represents $200 annually, making the distinction between 325 bps and 350 bps a $5,000 per year difference.

The term originates from the concept of a "basis" or base difference between two rates. While the unit is used across all financial markets, including bonds, derivatives, and foreign exchange, its most practical application for commercial borrowers is in understanding the true cost of capital and comparing competing loan offers with precision.

Understanding basis points gives borrowers a shared language with lenders. When a loan officer quotes a spread of "SOFR plus 250," they mean the interest rate will be the current Secured Overnight Financing Rate plus 2.50 percentage points. When a competing lender offers "SOFR plus 225," the borrower can immediately identify a 25 basis point advantage, which on a $5,000,000 facility translates to $12,500 in annual interest savings. Without fluency in basis points, borrowers risk misinterpreting rate quotes, overlooking meaningful cost differences, or failing to negotiate effectively.

Basis point literacy is equally important for tracking rate movements over time. If a borrower holds a variable-rate loan and the Federal Reserve raises its benchmark rate by 25 basis points, the borrower can calculate exactly how their monthly payment will change. For a $3,000,000 variable-rate loan, a 25 basis point increase adds approximately $625 per month to interest costs. This kind of precision supports better cash flow planning and more informed decisions about when to lock rates, refinance, or restructure existing debt.

Basis points also expose the true cost of fees that lenders sometimes describe in vague terms. An origination fee described as "one and a quarter points" is 125 basis points, which on a $4,000,000 loan equals $50,000. Borrowers who think in basis points can compare fee structures across lenders on equal footing, distinguishing between offers where one lender charges a lower rate but higher fees and another takes the opposite approach.

• Confusing basis points with percentages. Saying a rate "went up 50 basis points" and a rate "went up 50%" are vastly different statements. A 6% rate that increases by 50 basis points becomes 6.50%. A 6% rate that increases by 50% would become 9%. Always confirm which unit is being used.
• Ignoring small basis point differences on large loans. A 15 basis point difference between two loan offers may seem negligible, but on a $10,000,000 Commercial Real Estate loan over a 10-year term, that gap represents approximately $150,000 in total interest. Small differences in bps compound into significant dollar amounts at commercial scale.
• Forgetting that fees and rates use the same unit. Borrowers sometimes compare rate quotes without factoring in origination fees, guarantee fees, and closing costs, all of which are expressed in basis points. A loan at 275 bps over SOFR with a 100 bps origination fee may cost more than a loan at 300 bps over SOFR with a 25 bps fee, depending on the hold period.
• Assuming basis points only apply to interest rates. Basis points are used across the entire cost structure of a commercial loan: spreads, fees, yield maintenance penalties, rate caps, and even the pricing of interest rate swaps. Borrowers who only associate bps with the headline rate miss important cost components.
• Misapplying the conversion in reverse. To go from a percentage to basis points, multiply by 100 (not divide). A 0.75% fee equals 75 basis points, not 0.75 basis points. This arithmetic error can distort cost comparisons by a factor of 100.
