What are your shortest, average, and longest times to replace a salary without VC?

I'm curious what the replacement timelines are in sorta the shortest, average, and longest cases. If you quit, say, a $45K/yr position, how long does it take for someone to be back at that with their own company or product without taking VC? (I'm excluding VC, because an answer such as "1 month" because the person took $500K in VC and paid themself a salary from that feels like it should be a separate discussion)
