How to use this calculator
- Enter the donation made to each institution and the mode of payment.
- Choose the category of the institution to match your situation.
- Read the deduction in each category and the total in the result.
This deduction is available under the old regime only; cash donations above a limit do not qualify.
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.
