House Rent Allowance (HRA) calculator helps salaried employees in India calculate the tax exemption on the HRA component of their salary, which is provided to cover rental accommodation expenses. The exemption is calculated as the lowest amount among three values: the actual HRA received, 50% (for metro cities) or 40% (for non-metro cities) of the basic salary plus Dearness Allowance, or the actual rent paid minus 10% of the basic salary plus Dearness Allowance. The HRA exemption calculator requires inputs such as basic salary, HRA received, actual rent paid, and city of residence to compute the exempt and taxable amounts. Would you like me to provide a specific HRA calculation example or a link to a popular online HRA calculator? Or is assistance needed to calculate HRA exemption for particular salary and rent details? This can be done with a tool or formula guidance. Let me know the preference.
