What is the Home Loan Tax Benefit Calculator?
This calculator illustrates potential deductions for one eligible borrower with a self-occupied home under the old regime. The tax references here apply to FY 2025-26 / AY 2026-27. It is not a complete tax-return or regime-comparison calculation.
For qualifying self-occupied housing, the old-regime illustration uses the ₹2 lakh Section 24(b) interest cap and the shared ₹1.5 lakh Section 80C limit. The new regime does not allow these self-occupied deductions. Let-out interest is treated differently and cannot be estimated safely from these inputs alone.
Enter only your eligible share of payments. Ownership, borrowing and actual contribution must be established separately; the calculator does not allocate a joint loan or assume a 50/50 split.
How does it work?
Enter annual principal and interest from your lender's certificate. This tool does not calculate an amortisation schedule from loan amount, rate and tenure. For the self-occupied old-regime illustration, it caps the entered eligible principal at ₹1.5 lakh and interest at ₹2 lakh. Enter principal only to the extent of your unused 80C allowance after other eligible payments.
The displayed impact is eligible deductions multiplied by the entered slab percentage. It excludes cess, surcharge, rebate effects and changes across tax slabs; it is not an exact tax saving. The ₹2 lakh interest illustration assumes qualifying acquisition/construction and completion conditions, not repair loans or every housing loan.
Let-out cases require rent, municipal taxes, other house-property income and loss information. The old regime permits limited set-off against other income and subject-to-conditions carry-forward; the new-regime guidance restricts these losses. This calculator has no such inputs and therefore displays “Requires tax review” for either regime.
Worked example
For one eligible self-occupied borrower under the old regime, assume ₹1 lakh eligible principal (within unused 80C capacity), ₹2.6 lakh annual interest and a 30% slab input. The illustration uses ₹1 lakh principal plus ₹2 lakh interest: ₹3 lakh × 30% = ₹90,000 before cess and surcharge. This does not establish which regime produces the lower total tax.
When to use this calculator
- 1To illustrate self-occupied deductions using your annual lender certificate and confirmed eligibility.
- 2After a repayment change, using actual eligible annual principal and interest rather than the outstanding balance.
- 3To identify cases needing a full tax calculation, including rental property and joint ownership.
Common mistakes to avoid
- ✕Entering the entire joint-loan payment instead of your eligible share.
- ✕Double-counting principal when employee EPF or other eligible payments already use the 80C allowance; employer EPF is not your own 80C contribution.
- ✕Treating deduction multiplied by slab rate as an exact tax saving or a reduction in the EMI due to the lender.
- ✕Assuming the self-occupied ₹2 lakh cap covers repair loans or cases that fail the completion conditions.
- ✕Using the self-occupied calculation for a rental property without computing house-property income and losses.
Frequently asked questions
- Can I claim Section 80EEA?
- The historical sanction window is 1 April 2019 to 31 March 2022, with a stamp-duty-value ceiling of ₹45 lakh and other conditions including first-home and Section 80EE eligibility. The window closing does not automatically end deductions on eligible existing loans. The toggle assumes you have verified eligibility; it does not check it or double-count interest used under 24(b).
- Is interest deductible under the new regime?
- Not for a self-occupied property in this illustration. Eligible let-out interest may enter the house-property calculation, but that does not mean the full interest is a saving against salary. Rental cases require professional review because this tool does not model rent or loss restrictions.
- Do co-owners split the ₹2 lakh cap equally?
- Do not divide the statutory cap automatically. Each eligible taxpayer is assessed separately; establish ownership, borrowing and actual payment shares first, then apply that person's limits and remaining 80C capacity. This calculator does not verify or allocate those shares. Obtain tax advice for your joint-loan facts.
- What documents support the inputs?
- Use the annual interest certificate, principal repayment record, ownership and loan documents, and completion or possession evidence where relevant. Additional deductions require their own eligibility evidence.
- Where can I verify these rules?
- See the Income Tax Department's “Salaried Individuals for AY 2026-27” guidance and the co-owner provisions in Section 26. Verify the applicable tax year before filing.
