Home Loan Tax Benefit Calculator — §24(b) Interest + §80C Principal

A home loan is one of the largest tax breaks available — but only in the old regime. You can deduct up to ₹2 lakh of interest a year under Section 24(b) on a self-occupied home, plus up to ₹1.5 lakh of principal repayment under Section 80C. This calculator shows your total deduction and the actual rupees of tax you save at your slab rate.

The Two Home Loan Deductions (Old Regime)

Section 24(b) — interest: up to ₹2,00,000 per year on a self-occupied property. For a let-out property the entire interest is deductible against rental income, but the net house-property loss you can set off against other income is capped at ₹2 lakh per year (the rest carries forward).
Section 80C — principal: the principal portion of your EMI qualifies within the overall ₹1,50,000 80C limit, which it shares with PF, ELSS, life insurance and so on.
Stamp duty & registration paid in the purchase year also count under 80C, within the same ₹1.5 lakh cap.

Your EMI splits into interest and principal — early in the loan most of it is interest. To see that split for your loan, use the home loan EMI calculator, which shows the interest and principal components over the tenure.

Section 80EEA — extra interest for affordable housing

First-time buyers of affordable homes (stamp value up to ₹45 lakh) who took the loan in the eligible window could claim an additional ₹1.5 lakh of interest under Section 80EEA, over and above the ₹2 lakh under 24(b). Check whether your loan sanction date qualifies, as this benefit applied to loans sanctioned within specific years.

Why this only matters in the old regime

The new tax regime does not allow the 24(b) interest deduction on a self-occupied home or the 80C principal deduction. So a borrower with large home-loan deductions is exactly the kind of taxpayer for whom the old regime can still win. Before deciding, run the comparison in our new vs old regime tool — the home-loan deductions you calculate here are the biggest input into that decision.

Worked example

Suppose you pay ₹2.5 lakh interest and ₹1.8 lakh principal in a year and are in the 30% slab. Your interest deduction is capped at ₹2 lakh and principal at ₹1.5 lakh, for a total deduction of ₹3.5 lakh. At 30% plus 4% cess, that saves you about ₹1,09,200 in tax for the year.

Frequently Asked Questions

In the old regime you can deduct up to ₹2 lakh of interest a year (Section 24b) on a self-occupied home plus up to ₹1.5 lakh of principal within the 80C limit. At a 30% slab, the maximum ₹3.5 lakh deduction saves roughly ₹1.09 lakh in tax including cess.

No. The new regime does not allow the Section 24(b) interest deduction on a self-occupied property or the Section 80C principal deduction. These benefits exist only in the old regime, which is why home-loan borrowers should compare both regimes.

Yes. The interest (up to ₹2 lakh) is claimed under Section 24(b) and the principal (within the ₹1.5 lakh limit) under Section 80C. They are separate sections, so you can claim both in the same year.

For a let-out property the full interest is deductible against the rental income, with no ₹2 lakh cap on the deduction itself — but the net loss from house property that you can set off against other income in a year is limited to ₹2 lakh, with the balance carried forward for up to 8 years.

Yes — stamp duty and registration charges paid in the year of purchase are deductible under Section 80C, within the overall ₹1.5 lakh limit it shares with the loan principal and other 80C investments.
