Recommendation
Important Notes:
- Financial arrangements in relationships should reflect both partners’ values and preferences – there’s no single “right” answer.
- Consider discussing how you’ll handle income changes, major purchases, and savings goals alongside regular expenses.
- Transparency and open communication matter more than the specific model you choose.
- Revisit your arrangement periodically, especially after significant life or income changes.
- The calculator provides financial analysis but doesn’t account for non-financial contributions to the household.
