This is a nice theoretical answer, but I am looking for something a little more practical. Also, assume that a company has already acquired all its "expensive capital" via venture markets and sale of private shares. Given the current metrics of the business, how should it decide how much "cheap capital" to acquire via the debt markets?

It’s perhaps a high level answer but it’s not theoretical, if you are interested in diving deep I would highly recommend Professor Damodaran’s corporate finance course, he is the gold standard and it’s available for free on YouTube. Without repeating the entire course I’ll try and expand. The critical business metric is free cash flow, all operational data leads to that. We can project the firms free cash flows out over a period of years. Now the question is: how much should we spend to get this stream of cash? It’s not simply less than the sum of the cash flows, because the ones that come later are worth less than the ones that come sooner. To account for this, we “discount” those cash flows at a specific rate, the weighted average cost of capital. This number is where we bring in the mix of debt and equity in the firm and contains the cost of equity financing and the cost of debt financing, which mostly has to do with what interest rate the firm can borrow at. There is an optimal quantity of debt that minimizes this discount factor, thus maximizing the value of the future cash flows, it’s convex. If we can spend less than those summed discounted cash flows, funded with that optimal mix of debt and equity, we are NPV positive. This means we are generating real economic profits with our business activities.

Super helpful. Thank you for this thoughtful answer and I'll check out the YouTube recommendation. Cheers!

I just want to thank you again for that YouTube recommendation for Prof. Damodaran’s course. It is exactly what I am looking for. In particular, the middle part of his course (“the financing decision”) is specifically about how to think about debt vs equity mix.

Enjoy! I hope you find corporate finance as cool as I do. He’ll cover this but keep in mind there are a few differences with a firm such as yours who’s investors are less diversified.

Why would a company take on expensive capital if cheaper capital is readily available?

If the cheaper capital is cheaper because it’s more restrictive.
