Frequently Asked Questions

It's a general guideline, not a strict rule. People with high housing costs, such as those in expensive rental markets, often exceed 50% on needs and that's not necessarily a problem \u2014 it's a starting point for reflection, not a pass/fail test.

The 50/30/20 rule groups debt repayment together with savings because both are about improving your financial position, rather than day-to-day living costs. Paying down debt faster than the minimum is, in effect, a form of saving.

A commonly cited range is 3 to 6 months of essential expenses, though the right number depends on job security, whether you have dependents, and other personal circumstances. This calculator gives you a starting estimate based on your entered expenses.

It means your entered expenses exceed your entered income for the month. Worth double-checking every figure is genuinely monthly (not annual or weekly), then looking at your Wants category first, since it's usually the most flexible.
