What this specific question is asking

Most wrong answers here are setup errors, not math errors. Confirm income type, gross annual income (₹), tax regime and deductions, old regime (₹) — units, periods and definitions — before you touch Income Tax Calculator India, and keep the output's unit attached when you use it.

Use the example (As a worked reference for “What Is Better New Tax Regime Or Old”,…) as a calibration run: reproduce it first, then change only income type. The output should track the change predictably; if it does not, the inputs are on mismatched bases.

Inputs to verify

Verify income type before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify gross annual income (₹) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify tax regime before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Verify deductions, old regime (₹) before calculation; if this value uses a different unit, period or definition, convert or restate it first.

Step-by-step check

Enter your gross annual income.
Choose the New regime or the Old regime.
If you picked Old, enter your total eligible deductions (the New regime ignores them).
Tap Calculate for the tax, the 4 percent cess, and your effective rate.

Worked example and sanity check

As a worked reference for “What Is Better New Tax Regime Or Old”, Worked example FY 2025-26, AY 2026-27 · old regime · income type: salary / eligible pension. On ₹7,00,000 gross salary the salary standard deduction of ₹50,000 applies (it does not apply to freelance / business / other income); assuming no other eligible deductions, taxable income is ₹6,50,000. Under the old-regime slabs (nil to ₹2,50,000; 5% on ₹2,50,001–5,00,000; 20% above ₹5,00,000): ₹12,500 + 20% × ₹1,50,000 = ₹42,500 , plus 4% health & education cess = ₹44,200. This calculator adds the 4% cess and applies the new-regime simplified rebate-threshold marginal relief just above ₹12,00,000, but does not calculate surcharge or other high-income marginal relief . These are FY 2025-26 / AY 2026-27 figures, not timeless “current rates.” Compare the resulting magnitude with the calculator result; if those disagree materially, inspect the setup before trusting the decimal precision.

Interpreting the result

So what does the number mean? In the worked example the calculation produced ₹6,50,000. A result in that range is plausible for this kind of input; if your result lands far from it, revisit income type first — it is the input most often entered on the wrong basis. Read the magnitude before the decimals: a result ten times too large or small almost always means a unit or period slipped, not that the formula failed.
