Important assumptions and limitations

50/30/20 is a guideline, not a requirement. High housing, care or debt costs may make a different allocation more realistic.

Calculator outputs are estimates unless the underlying arithmetic is exact by definition. For decisions involving tax filing, lending, health, contracts or institutional grading rules, use the calculator as a first check and confirm the final decision with the relevant authoritative source.
