A budget translates priorities into numbers. The most popular frameworks are 50/30/20 (needs/wants/savings), zero-based budgeting (every franc assigned a job) and envelope budgeting (cash or virtual envelopes per category).
The act of tracking — not the method — drives results. Most overspenders simply do not know where the money goes. Modern apps (YNAB, Monarch, Lunchmoney) and bank-built tools automate categorisation, but the discipline of a monthly review is the active ingredient.
A household earning CHF 8,000 net per month allocates CHF 4,000 to needs (rent, food, utilities), CHF 2,400 to wants and CHF 1,600 to savings — a textbook 50/30/20 split.
