How to use this calculator
- Enter the loan sanction date, the stamp duty value, the interest paid and the loan outstanding.
- Choose the loan date to match your situation.
- Read the extra deduction allowed and the interest already claimed in the result.
The deduction applies only to loans sanctioned within a stated window; confirm the dates and conditions.
The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
