One of the strongest predictors of long-term financial stress is not income. It is whether you have any cash cushion at all. A 2019 Federal Reserve study found that 37 percent of Americans cannot cover an unexpected $400 expense from cash on hand. They borrow from cards, family, or payday lenders instead, and the cycle repeats.
What the buffer does
Setting a safety buffer in Finvy tells the AI engine: never recommend a payment that would push my checking balance below this number. With a $50 buffer, if your checking holds $300 right before payday and you have $200 of scheduled payments, the engine sees $50 of true surplus, not $100. You are protected from the small, unpredictable hits that turn into overdraft fees and missed payments.
How to pick a number
Most users start at $50 to $100. The right number depends on how variable your spending is. If you pay rent through autopay on the first of the month and have steady weekly income, $25 is fine. If you have unpredictable expenses or kids, $200 to $500 is safer. The buffer is editable in Settings any time.
