Definition
A Rule of Thumb is a heuristic guideline that provides simplified advice or a basic rule-set regarding a particular subject or course of action. These guidelines usually arise from practice and experience, rather than from scientific research or a theoretical framework, offering practical instructions for accomplishing or approaching a certain task.

Examples
-
30% Rule for Housing: A popular rule states that one should spend no more than 30% of their gross income on housing. Remember, this only applies if you don’t decorate the entire house with gold trim and a moat!
-
50/30/20 Budgeting Rule: This rule recommends allocating 50% of your income to necessities, 30% to wants, and 20% to savings and debt repayment. Just don’t confuse “wants” with buying 10 pairs of the same shoes!
-
Savings Milestones: It is often suggested to have 1x your salary in savings by 30, 3x by 40, and 6x by 50. Or you can just hoard Monopoly money—it’s much easier to count!
