How much is a “substantial” E-2 investment?

Substantiality weighs the amount invested against the total cost of either purchasing an established enterprise or creating a new one. The test is relative, not absolute.

The practical consequence: the lower the total cost of the business, the higher the proportion of that cost the investor must commit. A low-cost service business may need close to 100% of its cost invested to qualify, while a capital-intensive business can be substantial at a lower percentage.

Because the test is proportional, a number that is plainly substantial for one business is plainly inadequate for another. A figure that comfortably starts a consulting practice would not credibly establish a manufacturing operation.

Anchoring on a rumored threshold (often quoted figures like $100,000) is a mistake. Some approvals sit well below common rules of thumb; some businesses need far more. The right number is the one proportional to that specific enterprise’s cost.

Since the percentage depends on the cost of the business, that cost must be documented. For a startup it is the realistic cost to get to operation — equipment, build-out, inventory, licenses, and working capital. For an acquisition it is the purchase price plus what it takes to operate.

A defensible use-of-funds breakdown does double duty here: it documents the denominator and shows the capital is deployed, not idle.

Present the investment as a proportion, not just a sum. Showing that the committed capital covers a high share of the documented startup cost is more persuasive than a large number with no context.

Working capital reserves count when they are genuinely committed to the operation. Pair the figure with the financial projections so the amount looks sufficient to reach the revenue the plan promises.
