Your operating-cash-flow-to-total-assets ratio is 20 percent, or $300,000 divided by $1.5 million, times 100. This means you produce 20 cents of operating cash flow for every dollar of assets you own.

If total cash flow is $50,000, you expand your operations, and cash flow rises to $52,000 as a result of the expansion, then the incremental cash flow from the expansion is $2,000.
