Key takeaways
- It is easy to underestimate monthly spending.
- Add up every purchase across all cards and accounts for the last three full months.
- MonthlyIQ connects your accounts, pairs transfers and card payments automatically, and leaves them out of spending — so the total you see is what you actually spent.
Why the number feels fuzzy
It is easy to underestimate monthly spending. Annual renewals, card payments, and transfers between your own accounts all blur the real picture.
Your bank statement shows money moving, not money spent. Paying a credit card from checking isn't new spending — it's a transfer.
A clean method
Add up every purchase across all cards and accounts for the last three full months.
Remove transfers between your own accounts and credit card payments.
Divide by three. That's your real monthly spending.
