When does it make sense to take out loans versus pay cash for college?

Pay cash when you genuinely can do so without raiding your emergency fund or cutting retirement contributions – it's debt-free and avoids years of interest. Lean toward borrowing when paying cash would force you to stop funding your 401(k), drain a safety net, or sell investments at a bad time, since modest student debt is recoverable but a gutted retirement is not. The smart middle path is usually a blend: pay what you comfortably can from savings and current income, then borrow a limited amount – ideally federal student loans first – to cover the rest. A useful test is whether the cash payment would leave you financially fragile; if it would, borrowing a portion is the prudent move. Keep total borrowing tied to realistic post-graduation income.
