How this works
This converts your annual CTC (cost to company) into monthly take-home pay under Indian tax rules — applying the standard deduction (₹75,000 under the new regime, ₹50,000 under the old), any PF and professional tax you enter, then the applicable income tax slabs, to arrive at what actually lands in your account each month.
Common questions
Why is the standard deduction different for old vs new regime?
That's simply how each regime is currently structured — the new regime's ₹75,000 was raised specifically to make it more attractive after deductions, while the old regime keeps ₹50,000 but allows many more deductions (HRA, 80C, etc.) that the new regime mostly doesn't.
Does this account for HRA or other exemptions?
Only what you enter as a deduction under the old regime — it doesn't automatically calculate HRA exemption from your rent and salary structure, since that depends on several inputs beyond what this calculator asks for.
