Tax Saving Calculator
How much old-regime tax an 80C-style investment actually saves at your income — computed across real slabs and cess, not a flat rate.
What this tax saving calculator does
"Invest ₹1,50,000 and save ₹46,800 in tax" — you have seen the pitch. This calculator shows what that number actually is for your income. It computes the old-regime tax you would pay without the investment, then with it, and reports the difference between two complete slab calculations — slab boundaries, cess and surcharge all included, never a flat percentage multiplied by the investment.
That distinction matters. The real saving depends on which slab your deduction lands in: the same ₹1,50,000 saves ₹46,800 for someone earning ₹15,00,000 but only ₹31,200 at ₹8,00,000. Note that 80C-style deductions only reduce tax in the old regime — if the new regime is already cheaper for you, investing purely "to save tax" may not be worth it.
How the saving is computed
Tax saved = Tax(income) − Tax(income − deduction)
- Tax(income) — full old-regime tax on your income with no deduction: slabs, 87A rebate where it applies, surcharge and 4% cess
- Tax(income − deduction) — the same complete calculation after subtracting your 80C investment (capped at ₹1,50,000)
- Effective saving rate — tax saved ÷ investment, e.g. ₹46,800 ÷ ₹1,50,000 = 31.2%
Running the slab table twice is what keeps the answer honest when a deduction straddles two slabs — a marginal-rate shortcut would get those cases wrong.
How to use this calculator
- Enter your annual gross income before any deductions.
- Set the planned 80C investment — anything from ₹0 to the ₹1,50,000 ceiling.
- Pick the income type: Salaried applies the ₹50,000 old-regime standard deduction automatically.
- Choose the financial year whose slab rates should apply.
You get the tax with and without the investment, the rupee saving, and the effective saving rate on every rupee invested.
A worked example
₹15,00,000 salary, ₹1,50,000 in 80C, FY 2025-26 (old regime):
- Tax without the investment: taxable ₹14,50,000 → ₹2,57,400
- Tax with the investment: taxable ₹13,00,000 → ₹2,10,600
- Tax saved: ₹46,800 — an effective 31.2% of the amount invested
At this income the whole deduction sits in the 30% slab, so the saving is 30% plus the 4% cess on it: ₹45,000 × 1.04 = ₹46,800.
What a full ₹1,50,000 in 80C saves at different incomes
| Gross salary | Tax without | Tax with | Tax saved | Effective rate |
|---|---|---|---|---|
| ₹8,00,000 | ₹65,000 | ₹33,800 | ₹31,200 | 20.8% |
| ₹12,00,000 | ₹1,63,800 | ₹1,17,000 | ₹46,800 | 31.2% |
| ₹15,00,000 | ₹2,57,400 | ₹2,10,600 | ₹46,800 | 31.2% |
| ₹20,00,000 | ₹4,13,400 | ₹3,66,600 | ₹46,800 | 31.2% |
Salaried taxpayer below 60, FY 2025-26 old regime, cess included. The saving plateaus at ₹46,800 once the entire deduction falls inside the 30% slab — investing more than ₹1,50,000 in 80C instruments earns no additional deduction.
No. The new regime disallows section 80C (and most other Chapter VI-A deductions). The saving this calculator shows is old-regime tax saved — so first check, with the income tax calculator, whether the old regime plus your deductions actually beats the new regime for you.
The common ones: EPF and VPF contributions, PPF, ELSS mutual funds, life insurance premiums, NSC, 5-year tax-saver fixed deposits, Sukanya Samriddhi deposits, home-loan principal repayment, and children's tuition fees. They all share the single ₹1,50,000 ceiling.
Combined. Sections 80C, 80CCC and 80CCD(1) together are capped at ₹1,50,000 a year. An extra ₹50,000 is available separately under section 80CCD(1B) for your own NPS contributions, taking the practical old-regime total to ₹2,00,000.
Because the saving happens at your marginal slab. If part of your deduction falls in the 20% slab — typical below roughly ₹10,00,000 of taxable income — that part saves 20.8% including cess, not 31.2%. The calculator handles the split automatically.
Yes — health insurance premiums under 80D (₹25,000, or ₹50,000 for senior-citizen parents), the extra ₹50,000 NPS window under 80CCD(1B), home-loan interest up to ₹2,00,000 under section 24(b), education-loan interest under 80E, and donations under 80G, among others.
