Let's start from basics. Pen down both of your monthly salaries, expenses (even with 2$ spent on tea c)

Now if it falls in below bracket then you no need to bother or else you should revise your satergies

40% - Expense

30% - Short term savings

20% - long term savings

10% - insurance, hospital plan, medical

​

Priority should be as below

1. Protection for uncertainty
2. Savings for short term like emergency fund
3. Savings for retirement
4. Expenses

Depend on each couple, else 50/50 is fair
