Your regime choice is one decision of many.

FinPlan keeps your real salary, loans, goals and investments in one place, and shows which regime wins as your deductions actually change through the year.

How to read this

The new regime has lower slabs and a larger standard deduction, but allows almost nothing else. The old regime taxes you at higher rates and then lets you subtract HRA, 80C, 80D, NPS and home-loan interest first. So the old regime wins only once you genuinely claim enough — and claiming here means money actually spent or invested, not the cap.
