How Interest Rates Affect Business Valuations

Every business owner planning an exit wants to know the same thing: is now a good time to sell? And inevitably, the conversation turns to interest rates. Having advised on dozens of transactions across different rate environments, I can tell you that rates matter — but probably not in the way you think.

Interest rates affect business valuations through two distinct channels, and understanding both is critical to making informed decisions about your exit timing.

Channel One: The Cost of Financing

Most business acquisitions involve leverage — borrowed money. When interest rates go up, debt service goes up, which means buyers can afford to pay less for the same business. This is the most direct and immediate impact of rate changes on valuations.

The math is straightforward. Consider a business generating $1M in annual cash flow. At 5% interest rates, a buyer borrowing $3M to fund the acquisition pays $150K/year in interest. At 8% rates, that same $3M loan costs $240K/year — $90K more in annual debt service. That $90K has to come from somewhere, and it usually comes from the purchase price.

This is especially pronounced in the lower middle market where buyers are more reliant on debt financing. A strategic acquirer with $500M in cash on their balance sheet doesn't care much about interest rates. A search fund buying a $5M business with 60% leverage cares enormously.

How SBA Lending Is Affected

For businesses under $5M in enterprise value, SBA 7(a) loans are the dominant financing mechanism. SBA rates are variable, typically pegged at Prime + 2.75% for loans over $350K. When the Fed raises rates, Prime moves in lockstep, and every SBA-financed acquisition gets more expensive overnight.

In the near-zero rate environment of 2020-2021, SBA 7(a) rates bottomed around 5.5-6.0%. By late 2023, they peaked at approximately 11.0-11.5%. That's nearly double the debt service cost. A buyer who could comfortably service a $2M SBA loan at 6% suddenly could only afford $1.5M at 11% — assuming the same cash flow coverage ratios.

The practical impact? In high-rate environments, I've seen SBA-financed deals where buyers ask sellers to carry 15-25% of the purchase price as a seller note at below-market rates. This effectively subsidizes the buyer's borrowing cost. Sellers who refuse often find their buyer pool shrinks dramatically.

How PE Leverage Changes

Private equity firms live and die by leverage. In the low-rate years, PE firms routinely financed acquisitions at 4-5x debt/EBITDA. A PE firm buying a $10M EBITDA business might borrow $40-50M against it. When rates rose, lenders pulled back, and leverage ratios dropped to 2.5-3.5x. That's 25-30% less borrowed capital per deal.

Less leverage means PE firms need more equity per deal, which compresses their returns and forces them to be more disciplined on entry multiples. The result is predictable: when rates rise, PE offer multiples tend to contract by 0.5-1.5 turns across the board.

Channel Two: Discount Rates and DCF Valuations

The second channel is more theoretical but equally important, especially for larger transactions where discounted cash flow analysis plays a role in the valuation.

In a DCF model, the value of a business is the present value of its future cash flows, discounted at a rate that reflects the riskiness of those cash flows. The discount rate is built on the risk-free rate (typically the 10-year Treasury yield), plus a risk premium for the specific business.

When the 10-year Treasury moves from 1.5% (early 2022) to 4.5% (2023-2024), the discount rate for every business in America goes up by roughly 3 percentage points. For a business generating $1M in perpetual cash flow, increasing the discount rate from 15% to 18% drops the present value from $6.67M to $5.56M — a 17% decline in theoretical value, with no change in the underlying business.

In practice, few small business transactions use formal DCF analysis. But the principle still applies indirectly: higher risk-free rates mean all alternative investments become more attractive relative to buying a business, which puts downward pressure on what buyers are willing to pay.

Historical Evidence: Rates and M&A Multiples

The correlation between interest rates and M&A multiples is real but far from perfect. Looking at our database of 25,000+ transactions, the patterns are instructive.

2010-2015 (rates near zero):Median EV/EBITDA multiples for sub-$25M deals ranged from 4.5-5.5x. Multiples were rising but hadn't yet reached their peak — there was still a post-recession hangover in buyer confidence.

2016-2019 (gradual tightening): Despite the Fed raising rates from 0.5% to 2.5%, multiples continued climbing. Median EV/EBITDA hit 5.5-6.5x for SMB deals. Why? Because the economy was growing, PE dry powder was at record levels, and business confidence was high. Rates were rising, but not fast enough to offset other tailwinds.

2020-2021 (emergency cuts):Rates crashed back to zero, stimulus flooded the economy, and M&A activity exploded. Multiples surged to record highs. Sub-$25M deal multiples hit 6-8x in many industries.

2022-2024 (aggressive tightening): The most rapid rate-hiking cycle in 40 years did compress multiples — but less than most people expected. Median multiples pulled back 0.5-1.5 turns from the 2021 peak, settling around 5-6.5x for most industries. Deal volume fell more than deal pricing.

The lesson? Rates are a factor, but they're one factor among many. Business quality, industry dynamics, buyer competition, and seller preparation often matter more.

The 2026 Rate Environment: What It Means for Sellers

As of early 2026, we're in what I'd call a "normalized" rate environment. The Fed funds rate has come down from its peak but remains well above the near-zero levels of 2020-2021. SBA 7(a) rates are in the 8-9% range. PE leverage is available but disciplined.

For sellers, this means a few things:

• Multiples have stabilized.The post-2021 correction is largely complete. Sellers shouldn't expect the frothy multiples of 2021, but the current market is healthy and active.
• Deal structure matters more than ever. In a higher-rate environment, how the deal is financed — seller notes, earn-outs, rollover equity — can affect your net proceeds as much as the headline multiple.
• Cash flow quality is paramount. Buyers with more expensive debt scrutinize cash flow sustainability more carefully. Lumpy, one-time, or declining revenue gets penalized harder when debt service eats more of the cash flow.
• Buyer mix is shifting. Higher rates have disproportionately impacted leveraged buyers (PE, search funds). Strategic buyers with cash on their balance sheets are relatively unaffected. If your business is attractive to strategics, you may not feel much rate impact at all.

Why Timing the Rate Cycle Is Usually a Mistake

I hear it constantly: "I'll wait for rates to come down before I sell." In my experience, this is almost always the wrong approach, and here's why.

You can't predict rates.In January 2022, most economists expected rates to stay low. By December, the Fed had executed the most aggressive tightening cycle in decades. If the PhD economists at major banks can't forecast rates reliably, neither can you or I.

Your business has a shelf life.Businesses don't stay at peak performance forever. I've watched owners delay selling for "better market conditions" only to see their business decline — a key employee left, a major customer churned, a competitor emerged. The optimal time to sell is when your business is performing well, not when macroeconomic conditions are theoretically perfect.

Rate cuts often coincide with recessions. The Fed cuts rates when the economy weakens. So waiting for lower rates might mean selling into a recession, where buyer confidence is low, deal volume has collapsed, and your own revenue may be declining. Be careful what you wish for.

The spread matters more than the level.What affects your sale price isn't the absolute level of rates but how rates interact with your specific buyer pool. A business with strong cash flows and multiple strategic buyers will sell well at any rate level. A highly leveraged transaction targeting financial buyers will be rate-sensitive regardless.

What You Can Actually Control

Instead of trying to time interest rate cycles, focus on the factors you can control that have a far greater impact on your business valuation.

• Revenue quality: Recurring revenue commands higher multiples in any rate environment. Convert project work to service contracts.
• Growth trajectory: A business growing 15% annually will attract premium offers regardless of rates. A declining business will struggle to sell in any environment.
• Owner independence: A business that runs without the owner is worth more to every buyer type. Build management depth.
• Financial cleanliness: Three years of audited or reviewed financials eliminate friction from the sale process and give buyers confidence to pay up.
• Competitive process: Running a structured sale process with multiple qualified buyers does more for your price than any macro tailwind.

The Bottom Line

Interest rates are a real input to business valuations, and understanding the mechanics helps you set realistic expectations. But in my experience, business owners who obsess over macro timing almost always leave money on the table compared to those who focus on making their business as strong and sellable as possible, then execute a disciplined sale process when they're ready. The rate environment is one chapter of the story. Your business fundamentals are the whole book.
