Section 80C Tax Savings Calculator (FY 2025-26)
Section 80C of the Income Tax Act lets you deduct up to ₹1,50,000 a year from your taxable income for investments like PPF, ELSS, life insurance premiums, EPF, 5-year tax-saving fixed deposits, and home loan principal repayment. This calculator shows the actual rupee amount of tax you save by claiming a given Section 80C investment — not just the deduction amount itself. Section 80C benefits are available only under the old tax regime; the new regime does not allow this deduction at all. If you're unsure which regime suits you, use the Old vs New Tax Regime Calculator first.

What is the Section 80C Tax Savings Calculator?
Section 80C is the most widely used deduction in the Income Tax Act, letting individuals reduce their taxable income by up to ₹1,50,000 a year through eligible investments and payments. But the deduction amount itself isn't the same as the tax you save — the actual saving depends on which income slab that ₹1,50,000 falls into. This calculator computes your tax twice, once on your full taxable income and once after subtracting your Section 80C investment, and shows you the difference in rupees.
Section 80C applies only to the old tax regime. The new tax regime, now the default option, does not permit a Section 80C deduction under any circumstances — it trades away most deductions in exchange for lower slab rates. If you're not sure whether the old regime's deductions (including 80C) beat the new regime's lower rates for your income, check the Old vs New Tax Regime Calculator before deciding where to invest for tax savings.
How to use this calculator
- Enter your taxable income before Section 80C — that is, your gross income after the standard deduction, HRA exemption, and any other exemptions have already been subtracted, but before subtracting Section 80C.
- Select your age category, since the old regime's basic exemption limit depends on age.
- Enter the amount you plan to invest (or have invested) under Section 80C, up to the ₹1,50,000 annual cap.
- Select "Calculate Tax Saved" to see your tax payable with and without the deduction, the total tax saved, and your effective marginal savings rate.
Formula
"Old Regime Tax" here includes the progressive slab tax for your age category, the Section 87A rebate (with marginal relief near its threshold), surcharge, and 4% health & education cess — the same computation used by the Income Tax Calculator. See the editorial policy for how these figures are sourced and kept current.
Example
Consider a taxpayer below 60 with a taxable income of ₹9,00,000 before Section 80C, claiming the full ₹1,50,000 deduction. Without 80C, slab tax on ₹9,00,000 works out to ₹92,500 (₹12,500 on the ₹2,50,000–₹5,00,000 band at 5%, plus ₹80,000 on the ₹5,00,000–₹9,00,000 band at 20%); income is well above the ₹5,00,000 rebate threshold, so no rebate applies, and adding 4% cess brings total tax to ₹96,200. With the ₹1,50,000 deduction, taxable income drops to ₹7,50,000, and slab tax comes to ₹62,500 (₹12,500 plus ₹50,000 on the remaining ₹2,50,000 at 20%); again no rebate applies, and 4% cess brings total tax to ₹65,000. The tax saved is ₹96,200 − ₹65,000 = ₹31,200 — exactly what you'd expect from ₹1,50,000 taxed at this person's 20% marginal slab plus 4% cess (₹1,50,000 × 20% × 1.04 = ₹31,200), since their entire 80C deduction fell within the 20% slab.
Factors that affect your Section 80C tax saving
- Regime is fixed to old. Section 80C benefits are exclusive to the old tax regime — there is no equivalent under the new regime, so this calculator does not offer a regime toggle. Use the Old vs New Tax Regime Calculator separately to see which regime is cheaper overall for you.
- Your marginal tax slab, not a fixed percentage. The rupee saving from claiming 80C depends on which slab(s) the deducted amount falls into. The same ₹1,50,000 deduction can save ₹0 (income below the basic exemption), roughly ₹5,200 (fully in the 5% slab), roughly ₹31,200 (fully in the 20% slab), or more (in the 30% slab), depending on your income.
- The statutory cap. Section 80C is capped at ₹1,50,000 per financial year, combined across every eligible instrument you invest in — PPF, ELSS, life insurance, EPF, and the rest all share the same limit rather than each getting their own.
- Age category. Senior citizens (60–80) and super senior citizens (80+) have a higher basic exemption limit under the old regime, which can change how much of a given 80C deduction falls into a taxed slab versus the exempt band.
- Surcharge smoothing. For very high incomes, this calculator applies a flat surcharge slab rate and does not smooth the small marginal-relief band right at each surcharge threshold (₹50L, ₹1Cr, ₹2Cr, ₹5Cr) — the same documented limitation as the Income Tax Calculator.
Frequently Asked Questions
Common options include Employee Provident Fund (EPF) contributions, the Public Provident Fund (PPF), Equity Linked Savings Scheme (ELSS) mutual funds, life insurance premiums, 5-year tax-saving fixed deposits, National Savings Certificates (NSC), Sukanya Samriddhi Yojana, and principal repayment on a home loan. All of these are grouped under one combined ₹1,50,000 annual limit — you don't get a separate ₹1,50,000 for each instrument.
The new tax regime was designed around lower slab rates in exchange for giving up most deductions and exemptions, including Section 80C. It only allows a small set of benefits, mainly the standard deduction and the employer's contribution to NPS under Section 80CCD(2). If you rely heavily on 80C investments to reduce your tax, the old regime may still work out cheaper even with its higher slab rates — compare both with the Old vs New Tax Regime Calculator.
Yes, but only under the old regime, and only if you invest in something outside the 80C list. The most common example is the additional ₹50,000 deduction for NPS contributions under Section 80CCD(1B), which sits on top of — and separately from — the ₹1,50,000 Section 80C limit. This calculator only computes the Section 80C benefit; use the NPS Calculator to explore your NPS contribution separately.
Any amount above ₹1,50,000 in a financial year does not reduce your taxable income any further — the deduction is capped by law regardless of how much more you invest. This calculator enforces the same cap, so entering more than ₹1,50,000 will show a validation message rather than an inflated tax-saving figure. Extra contributions may still be worthwhile for their own returns (e.g. PPF's interest rate) even though they stop producing an additional tax benefit.
Not automatically. The old regime's higher slab rates can outweigh the tax saved from Section 80C and other deductions, depending on your income and how much you actually invest. Use this calculator to see your Section 80C tax saving under the old regime, then compare the resulting total tax to what you would pay under the new regime using the Old vs New Tax Regime Calculator before deciding.
