Debt-to-income ratio is a term most business owners associate with mortgages or personal loans, but it plays a role in business funding decisions too – especially when a personal guarantee is involved or when a business is newer and underwriters lean more heavily on the owner’s personal financial profile. Here’s how it factors into approval, and what to do if yours isn’t where you’d like it to be.
What Debt-to-Income Ratio Actually Measures
Debt-to-income ratio, or DTI, compares total monthly debt obligations against gross monthly income. For an individual, that includes things like mortgage or rent, auto loans, credit card minimums, and other personal debt, divided by income from all sources. When a business funding application involves a personal guarantee – common with many SBA loans and some term loans – the guarantor’s personal DTI can become part of the underwriting picture alongside the business’s own financials.
Why It Matters Even for Business Financing
When an owner personally guarantees a loan, they’re agreeing to be personally responsible for the debt if the business can’t pay. Underwriters want to know whether that owner already has significant personal debt obligations that could strain their ability to step in if needed. A high personal DTI can raise concerns even if the business itself looks strong on paper, since it signals less personal financial cushion behind the guarantee.
How DTI Differs From Business-Level Metrics
It’s worth distinguishing personal DTI from business-level measures like debt service coverage ratio, which looks purely at the business’s own cash flow versus its debt. A business can have excellent cash flow and a strong DSCR while the owner personally carries a high DTI from unrelated personal obligations, or vice versa. Products that don’t require a personal guarantee, or that weigh business cash flow more heavily than personal financial history, can be a better fit for an owner whose personal DTI doesn’t reflect the health of the business itself.
What Counts as a Reasonable DTI
There’s no single fixed number that applies across every funding source, since underwriting standards vary by product and lender. As a general guideline, many lenders view a personal DTI under roughly 40% to 45% favorably, though this is just one factor among several rather than an automatic cutoff. Business revenue, time in business, and industry all factor into the overall decision alongside personal DTI when a guarantee is part of the deal.
How to Improve Your Position Before Applying
Paying down high-balance revolving debt, such as credit cards, tends to move the needle faster than paying down installment debt like a fixed auto loan, since revolving balances are weighted heavily in most DTI calculations. It’s also worth considering whether a funding structure that doesn’t rely on a personal guarantee – such as a merchant cash advance based primarily on business revenue, or certain business lines of credit – might be a better fit if personal DTI is a limiting factor right now.
Frequently Asked Questions
Does my personal debt-to-income ratio affect my business loan application?
It can, particularly if the financing requires a personal guarantee. In those cases, underwriters often consider the guarantor’s personal DTI alongside the business’s own financial profile.
What debt-to-income ratio do I need for a business loan?
There’s no universal threshold, since it varies by lender and product. As a general guideline, a DTI under roughly 40% to 45% is often viewed favorably, but it’s typically weighed together with business revenue, time in business, and other factors rather than used as a strict cutoff on its own.
Can I get business funding without a personal guarantee if my DTI is high?
In some cases, yes. Certain funding products weigh business revenue and cash flow more heavily than personal financial history, which can make them a better fit when personal DTI is a limiting factor.
