50/30/20 Budget Rule Calculator

The 50/30/20 rule is one of the most popular and simple budgeting frameworks. Popularized by US Senator Elizabeth Warren, it divides your after-tax income into three categories: 50% for needs, 30% for wants, and 20% for savings and debt repayment. This calculator instantly shows you the exact amounts for each category based on your Danish net income.

How the 50/30/20 Rule Works

Needs (50%) include essential expenses like rent, utilities, groceries, insurance, and minimum loan payments. Wants (30%) cover everything you enjoy but could live without, such as dining out, streaming, hobbies, and vacations. Savings (20%) should go toward building an emergency fund, pension contributions, investments, or paying down debt faster than required. On a net income of 30,000 kr, that means 15,000 kr for needs, 9,000 kr for wants, and 6,000 kr for savings.

Adapting the Rule to Denmark

Since Denmark has high taxes but also strong public services, some categories may differ from other countries. For example, healthcare costs are minimal, but housing costs in cities like Copenhagen are high. If your housing alone exceeds 50% of your income, consider adjusting the ratios to 60/20/20 or finding ways to reduce housing costs. The key principle remains: always save at least 20% of your income.
