Section 80C Calculator

How the Section 80C Calculator Works

This calculator adds up your eligible Section 80C investments, applies the statutory 1,50,000 deduction cap, and estimates the income tax you save at your chosen slab rate. Enter your EPF/PPF, ELSS, life-insurance premiums and other 80C items, pick your highest slab, and read off the result instantly.

Section 80C of the Income Tax Act lets individuals and Hindu Undivided Families (HUFs) reduce their taxable income by investing in specified savings instruments. It is one of the most-used tax-saving sections in India, but only under the old tax regime.

The Formula

Deduction = min(total eligible 80C investments, 1,50,000) Tax saved ≈ Deduction × slab rate × 1.04

The 1.04 factor accounts for the 4% Health and Education Cess charged on top of income tax. The deduction lowers your taxable income, so the actual rupees saved equal the deduction multiplied by the marginal rate at which that income would otherwise have been taxed.

Worked Example

Suppose you invest 50,000 in EPF/PPF, 40,000 in ELSS, 25,000 in LIC and 30,000 in other 80C items, and your top slab is 30%:

• Total invested = 50,000 + 40,000 + 25,000 + 30,000 = 1,45,000
• Deduction = min(1,45,000, 1,50,000) = 1,45,000
• Tax saved = 1,45,000 × 30% × 1.04 = 45,240

If you had instead invested 1,80,000, the deduction would still be capped at 1,50,000, saving 1,50,000 × 30% × 1.04 = 46,800.

Tax Saved by Slab

The table below shows the maximum tax you can save by claiming the full 1,50,000 deduction at each common slab, including the 4% cess.

Highest slab rate	Deduction claimed	Approx. tax saved
5%	1,50,000	7,800
20%	1,50,000	31,200
30%	1,50,000	46,800

Old Regime vs New Regime

Section 80C is a key reason many salaried taxpayers still choose the old regime. The new regime offers lower headline slab rates but disallows most deductions, including 80C. Compare both regimes’ total tax before deciding — the deductions you can genuinely claim often tip the balance.

Tips and Common Mistakes

• Count EPF automatically deducted from salary — your own EPF contribution already counts toward 80C, so you may need to invest less separately than you think.
• Don’t double-count — the same rupee cannot be claimed twice; the 1.5 lakh ceiling is shared across all instruments.
• Lock-in periods vary — ELSS has a 3-year lock-in, tax-saving FDs and NSC 5 years, PPF 15 years. Match the instrument to your horizon.
