1. Agree on your budget model
Pick one explicit structure: fully shared, partially shared, or mostly separate with shared obligations. Document the model so assumptions are clear.
2. Track the same core categories
- Housing and utilities
- Groceries and household costs
- Transport and commuting
- Subscriptions and recurring charges
- Debt payments
- Savings goals
3. Use a weekly + monthly rhythm
Weekly (10-15 min)
Review upcoming spending, confirm one-off purchases, and adjust this week's priorities.
Monthly (30-45 min)
Evaluate category totals, update savings targets, and make decisions for the next month.
4. Assign ownership
One owner tracks recurring bills, another tracks variable expenses, and both review together. Ownership reduces dropped items.
Tandem helps couples track shared finances alongside tasks and calendar planning.
