How to use the Tax Saving Investment Planning Calculator
Compare Indian old and new tax regimes for FY 2025-26 (AY 2026-27) using the current slab and rebate rules. This tool is designed for Indian users who want a quick estimate before comparing options, speaking with an advisor, or committing money. It helps you estimate tax impact, compare regimes, and understand deductions before making salary or investment decisions.
What this calculator answers
How much tax you can save with eligible deductions such as Section 80C and 80D, and whether they make the old regime worthwhile.
Practical tip
Choose tax-saving products for their own merit first. A deduction does not make an unsuitable product a good investment.
Worked example
Using the full Rs 1.5 lakh Section 80C limit saves up to Rs 46,800 in tax for someone in the 30% bracket under the old regime, including cess. The same investment gives no deduction under the new regime.

Formula and methodology
Tax calculators apply slab-based rules, eligible deductions, exemptions, surcharge or cess assumptions where relevant, and then estimate net liability from the entered income details.
WealthWiseGrow keeps calculator inputs private in your browser wherever possible. The result should be treated as an educational estimate and reviewed against the official product terms, bank quote, fund document, tax rule, or salary structure that applies to your situation.
Example interpretation
For example, the new regime may look simpler, but the old regime can still work better for users with HRA, 80C, home loan interest, medical insurance, or other deductions. A calculator makes the comparison visible.
After calculating, compare at least two scenarios: a conservative case and an optimistic case. This helps you avoid planning around a single number that may not survive changes in income, interest rates, inflation, tax rules, or market returns.
