The Post-Mortem Problem
Most budgeting apps show you a red bar at the end of the month. "You overspent groceries by €87." That information is useful, but only for next month. It doesn't help you this month.
Effective budgeting requires a forward-looking signal, not a backward-looking report. You need to know you're approaching the limit before you cross it.
The 70% Rule in Practice
Here's a simple rule used by financial planners: when you've spent 70% of a budget category, it's time to consciously decide whether to continue at the same pace.
At 70%, you haven't overspent. You have 30% remaining, which is a real decision point, not a crisis. You can adjust your behavior with time to spare.
"70% is a warning sign. 100% is already over. Get the warning, not the crash."
How FoxyFi Implements This
FoxyFi's budget system has a customizable alert threshold, defaulting to 70%. When your spending in a category reaches that threshold, you get a notification and the budget card changes color from green to amber.
The progress bar shifts from "safe" to "warning" state. Hit 100%? Another notification, the bar turns red. You're never surprised at month-end because the system warned you 30% ago.
Multi-Category Budgets
A single "Groceries" budget can span five categories: fresh produce, supermarkets, specialty food stores, farmers markets, online delivery. FoxyFi aggregates spending across all of them into one budget total, with a breakdown by sub-category.
You see the aggregate (how close you are to the limit) and the breakdown (which sub-category is driving the spend).
Month-Over-Month Learning
Every budget period creates a `BudgetPeriod` record. After three months, FoxyFi can show you whether your grocery spending is trending up, down, or stable, and whether your budget limit is realistic for your actual behavior.
Not a projection. A pattern. Set better limits based on what you actually spend, not what you think you should.
