Manage shared expenses and split bills fairly. Use 50/30/20 rule or create custom budget allocations.

Split a budget fairly and simply

This calculator helps allocate take‑home pay using popular rules like the 50/30/20 framework (needs/wants/savings) or your own custom percentages. It’s useful for personal budgeting and for splitting shared expenses with roommates or partners.

Enter your monthly income, adjust the category percentages, and choose pay frequency if needed. The results break down dollars per category so you can set targets for bills, discretionary spending, and savings goals. Revisit each month and tweak based on real spending.

Combine this with the Extra Payment and Savings Rate calculators to see how budget changes accelerate debt payoff and long‑term goals.

FAQs

Is 50/30/20 the best rule?

It’s a useful starting point, not a rule. If you have high‑interest debt, shift more to savings/debt. If housing costs are high, reduce wants temporarily.

How do we split shared expenses?

Common approaches: 50/50, proportional to income, or per‑category splits. Agree on a method, then track and reconcile monthly.

How often should I adjust my budget?

Review monthly and after any income or expense changes. Small, frequent adjustments keep budgets realistic and sustainable.
