How much can I spend on rent and bills?

Figuring out monthly spending limits requires listing every recurring expense—from rent and utilities to insurance and groceries—and subtracting them from your total income. Without a clear breakdown of these fixed costs, it is impossible to calculate true savings or determine how much money remains for personal use.

“So how much would all bills cost? Electrical, plumbing, mortgage, health insurance for both of us, car insurance, cell phone bill, gas for the car, internet? Give me a rough amount how much all this will cost a month because I know I’ll be paying most of it and the main reason why I’m asking is because I wanna know how much profit I’ll be making every month.”source ↗
