How Interest Rates Affect Your Business

Interest rates quietly shape the valuation landscape for private companies more than almost any other macroeconomic variable. When rates rise, the cost of capital increases, discount rates expand, and equity values typically compress. When rates fall, the opposite occurs, the cost of capital becomes less expensive, risk discount rates tighten, and valuations tend to increase.

For private companies, the effect is even more pronounced. Unlike public firms, private businesses rely heavily on bank financing, SBA programs, and private credit markets. Higher rates have the general effect of reducing borrowing capacity, decreasing free cash flow, and limiting business reinvestment of earnings necessary to support operations, all of which directly impact enterprise value. Lower rates generally improve leverage, increase cash flow, and encourage business reinvestment of profits.

The valuation mechanism is straightforward, equity value is the residual cash flow available after debt service, capital expenditures and reinvestment. As interest rates rise, more cash flow is consumed by financing costs and risk-adjusted discount rates increase. As rates fall, more cash flow is available for distribution to equity holders and valuations increase accordingly.

In today’s environment, understanding this relationship is essential for owners preparing for a sale, investors evaluating opportunities, and strategic financial decision making. Interest rates don’t just influence valuation; they define the boundaries of what buyers can pay and what sellers can expect.
