Account structure tip

Most couples manage money best with three accounts:

🏦

Joint account (ours)

Both salaries in, shared bills out. Rent, groceries, utilities, subscriptions.

🟢

Partner A's personal account

Partner A's guilt-free money. No questions asked — personal spending, savings, investments.

🔵

Partner B's personal account

Partner B's guilt-free money. Full autonomy, zero resentment.

Each partner auto-transfers their contribution to the joint account on salary day. The rest stays personal.
