I thought revenue was the standard accounting term in the US. I think of income as what I get to keep / freely reinvest, and revenue as a number that contains all kinds of hidden liabilities such as taxes, cost of sales, etc. That said, I’m (obviously) not an accountant.

When I look at it as a private person I think of income as the my personal revenue: from there I have lots of costs and tax to pay.

What I end up with is disposable income which I can keep/invest.
