Worked example and sanity check

As a worked reference for “How To Calculate Depreciation As Per Income Tax Act”, Worked example FY 2025-26, AY 2026-27 · old regime · income type: salary / eligible pension. Take ₹7,00,000 gross salary. The salary standard deduction of ₹50,000 applies (it would not apply to freelance / business / other income), and assume no other eligible deductions, giving ₹6,50,000 taxable. Under the old-regime slabs (nil to ₹2,50,000; 5% on ₹2,50,001–5,00,000; 20% above ₹5,00,000) the tax is ₹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 ; on business income the same ₹7,00,000 would be taxed without the ₹50,000 standard deduction. These are FY 2025-26 / AY 2026-27 figures, not timeless “current rates.” Compare the resulting magnitude with a hand calculation; if those disagree materially, inspect the setup before trusting the decimal precision.

Interpreting the result

Interpretation starts with magnitude. The worked example landed at ₹12,500 + 20% × ₹1,50,000 = ₹42,500 , plus 4% health & compare yours before trusting the decimals. If the two disagree wildly, the setup — usually income type's unit or period — is the suspect. Treat the figure as an estimate under stated assumptions, not a promise of returns or a lending decision; fees, taxes and rate resets will move the real outcome.
