For a $500K business loan, lenders typically require $1.5-3M in annual revenue and free cash flow that exceeds annual debt service by 25-50%. The exact requirement varies by lender type, loan structure, and industry.
The math underlying the bar is straightforward: lenders want confidence that the business can comfortably service the new debt without strangling operations. Here's how to back into the numbers.
The Core Math: DSCR
Debt Service Coverage Ratio (DSCR) = Annual free cash flow ÷ Annual debt service
For a $500K loan at 11% APR over 7 years, annual debt service is approximately $103K (monthly payment ~$8,580 × 12).
Bank DSCR target: 1.50x. Required annual free cash flow: $103K × 1.50 = $155K.
SBA DSCR target: 1.25x. Required annual free cash flow: $103K × 1.25 = $129K.
Online lender DSCR target: 1.10-1.20x. Required annual free cash flow: $113K-$124K.
Free Cash Flow vs Revenue
Free cash flow is roughly EBITDA (earnings before interest, taxes, depreciation, amortization) minus capital expenditures. For most small businesses, free cash flow is 5-20% of revenue depending on industry:
- Restaurants: 5-10% net margin → free cash flow ~5-12% of revenue
- Service businesses (legal, accounting, consulting): 15-25% net margin → free cash flow ~15-25% of revenue
- Retail: 3-7% net margin → free cash flow ~3-8% of revenue
- Construction: 5-10% net margin → free cash flow ~5-10% of revenue
- SaaS/software: 10-30% net margin → free cash flow ~10-30% of revenue
Revenue Requirements by Industry
For SBA 7(a) ($500K, 1.25x DSCR target, $129K free cash flow needed):
| Industry | FCF % of revenue | Annual revenue needed |
|---|---|---|
| Service business | 20% | ~$650K |
| Construction | 8% | ~$1.6M |
| Restaurant | 8% | ~$1.6M |
| Retail | 5% | ~$2.6M |
| SaaS | 25% | ~$520K |
Personal Income Requirement (Owner)
Lenders also look at personal income for the personal guarantee. The personal financial statement (SBA Form 413) requires:
- Personal salary/draws from the business
- Outside personal income
- Personal debt service (mortgage, car, credit cards)
- Personal net worth
For a $500K loan, lenders typically want the owner's personal financial position to be strong enough that the personal guarantee carries real weight. Generally:
- Personal liquidity: $50K+ in liquid assets (cash, brokerage accounts)
- Personal net worth: 25-50% of loan amount ($125K-$250K minimum)
- Personal debt-to-income: Under 45% including the new business loan obligation
Bank vs SBA vs Online Comparison
| Lender Type | FICO | Time in Business | Revenue | DSCR |
|---|---|---|---|---|
| Bank term loan | 700+ | 3+ years | $2M+ | 1.50x |
| SBA 7(a) | 650+ | 2+ years | $1M+ typical | 1.25x |
| Online term lender | 600+ | 1-2+ years | $500K+ | 1.10-1.20x |
If You Don't Meet the Revenue Bar
If your business genuinely needs $500K but doesn't have the revenue to support a traditional or SBA loan, two paths exist:
- MCA at $500K — typically requires $300K+ monthly revenue ($3.6M+ annual). Underwriting is based on bank statements, not P&L. Cost is much higher (~80% APR-equivalent) but qualification is more flexible. Westline funds $500K MCAs regularly to businesses with strong revenue but weak credit or short operating history.
- Smaller loan + growth — if revenue is $500K-$1M annual, a $100-200K loan might be more realistic. Use it to grow revenue, then refinance into a larger loan once the revenue supports it.
The Simplest Way to Estimate Your Bar
For a $500K loan, multiply your annual debt service ($103K at 11% over 7 years) by the lender's DSCR target. That's the free cash flow you need. Divide by your industry's typical free-cash-flow margin to estimate revenue requirement.
If your business comfortably exceeds those numbers and credit/time-in-business meet the lender's bar, $500K is achievable. If not, scale the loan size down or scale the path up to MCA.
