Tax Savings Calculator (FY 2025-26)
Most taxpayers under the old regime don't rely on just one deduction — they combine Section 80C investments with health insurance premiums, an additional NPS contribution, and home loan interest. This calculator adds up all four together and shows the actual rupee amount of income tax you save, by computing your old-regime tax once on your full income and once after subtracting everything you claim. All of these deductions are available only under the old tax regime; the new regime does not permit any of them. If you're unsure which regime suits you, use the Old vs New Tax Regime Calculator first.

What is the Tax Savings Calculator?
This is the comprehensive, multi-deduction version of a tax-savings calculator. The Section 80C Tax Savings Calculator is deliberately scoped narrowly to Section 80C investments only — PPF, ELSS, life insurance, EPF and similar instruments, capped at ₹1,50,000 — to keep that page focused and easy to reason about. This calculator instead combines Section 80C together with three other major old-regime-only deductions — Section 80D health insurance, Section 80CCD(1B) additional NPS contribution, and Section 24(b) home loan interest — into one combined "total tax savings" view, which the Section 80C calculator deliberately does not do. If you only want to check your Section 80C benefit specifically, use the Section 80C Tax Savings Calculator; use this one when you want to see your total old-regime tax savings across everything you're claiming.
All four deductions modelled here apply only to the old tax regime. Under the new tax regime for FY 2025-26, none of Sections 80C, 80D, 80CCD(1B) or 24(b) are available — the new regime only permits a flat standard deduction (and, for salaried employees, the employer's NPS contribution under Section 80CCD(2), which this calculator does not model). That's exactly why this calculator, like the Section 80C calculator, does not offer a regime toggle and always computes old-regime tax. If you're unsure whether the old regime's deductions still beat the new regime's lower slab rates for your income, check the Old vs New Tax Regime Calculator before deciding.
How to use this calculator
- Enter your gross taxable income before deductions — that is, your income after the standard deduction, HRA exemption, and any other exemptions have already been subtracted, but before subtracting the four deductions below.
- Enter your Section 80C investment amount, up to the ₹1,50,000 annual cap.
- Enter your Section 80D health insurance premiums separately for yourself/family and for your parents — these are two independent caps, not one combined limit.
- Enter your additional Section 80CCD(1B) NPS contribution, up to ₹50,000, over and above Section 80C.
- Enter your Section 24(b) home loan interest for a self-occupied property, up to ₹2,00,000.
- Select "Calculate Tax Saved" to see your total deductions claimed, taxable income after deductions, tax payable with and without the deductions, and your total tax saved.
Formula
"Old Regime Tax" here includes the progressive slab tax for a taxpayer below 60, 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 gross taxable income of ₹12,00,000, claiming the full amount under each section: ₹1,50,000 under Section 80C, ₹25,000 under Section 80D for self/family, ₹0 under Section 80D for parents, ₹50,000 under Section 80CCD(1B), and ₹2,00,000 under Section 24(b). Total deductions come to ₹4,25,000, bringing taxable income down to ₹7,75,000. Tax on the full ₹12,00,000 (old regime, below 60, including 4% cess) works out to ₹1,79,400. Tax on the reduced ₹7,75,000 works out to ₹70,200. The total tax saved is ₹1,79,400 − ₹70,200 = ₹1,09,200 — nearly one-fifth of the taxpayer's original income tax bill, entirely from deductions that only exist under the old regime.
Factors that affect your total tax saving
- Regime is fixed to old, age fixed to below 60. None of these four deductions exist under the new regime, so this calculator does not offer a regime toggle, and it always uses the below-60 age category. Senior and super senior citizens have a higher basic exemption limit, which would change the results slightly — use the Income Tax Calculator directly if you need an age-specific comparison.
- Your marginal tax slab, not a fixed percentage. The rupee saving from any deduction depends on which slab(s) the deducted amount falls into. The same ₹4,25,000 in combined deductions can save very different amounts depending on whether that income falls in the 5%, 20% or 30% slab.
- Two separate 80D caps. Section 80D for self/family and Section 80D for parents are independent limits, not one shared cap — a taxpayer with senior citizen parents can claim up to ₹25,000 + ₹50,000 = ₹75,000 in total, not a single ₹50,000 limit.
- 80CCD(1B) is additional, not part of 80C. The ₹50,000 NPS deduction under Section 80CCD(1B) sits on top of the ₹1,50,000 Section 80C limit and is never counted against it.
- Section 24(b) applies to self-occupied property only. The ₹2,00,000 cap modelled here is for a self-occupied home loan. A let-out property follows different rules with no such fixed cap on the interest deduction itself — this is a known limitation of this calculator, not modelled here.
- 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
The Section 80C Tax Savings Calculator is deliberately scoped to just Section 80C — PPF, ELSS, EPF, life insurance and similar instruments, capped at ₹1,50,000. This calculator is the comprehensive, multi-deduction version: it combines Section 80C together with Section 80D health insurance (self/family and parents separately), the additional Section 80CCD(1B) NPS deduction, and Section 24(b) home loan interest into one combined total tax-saving view. If you only want to check your 80C benefit specifically, use the Section 80C Tax Savings Calculator; use this one when you want to see your total old-regime tax savings across everything you're claiming.
The new tax regime, now the default option, trades away nearly all deductions and exemptions in exchange for lower slab rates. Section 80C, Section 80D, Section 80CCD(1B) and Section 24(b) on a self-occupied property are all unavailable under the new regime — it only permits a flat standard deduction and the employer's NPS contribution under Section 80CCD(2). That is exactly why this calculator, like the Section 80C calculator, does not offer a regime toggle and always computes old-regime tax. Use the Old vs New Tax Regime Calculator to see whether the old regime's deductions still beat the new regime's lower rates for your income.
No — this is a common point of confusion. Section 80D actually has two separate, independent caps rather than one combined limit. You can claim up to ₹25,000 for health insurance premiums for yourself and your family (rising to ₹50,000 if you or your spouse are a senior citizen), and separately, up to ₹25,000 for premiums paid for your parents (rising to ₹50,000 if your parents are senior citizens). A taxpayer with senior citizen parents could claim up to ₹25,000 + ₹50,000 = ₹75,000 in total, not a single shared ₹25,000 or ₹50,000 limit.
Section 80CCD(1B) allows a further deduction of up to ₹50,000 for your own contribution to the National Pension System (NPS), and this amount sits on top of — and separately from — the ₹1,50,000 Section 80C limit. It is not counted against your 80C cap, so an investor can claim the full ₹1,50,000 under 80C and an additional ₹50,000 under 80CCD(1B) in the same year, for up to ₹2,00,000 in combined deductions from these two sections alone. Use the NPS Calculator to explore your NPS contribution and projected corpus separately.
The ₹2,00,000 cap modelled by this calculator applies specifically to interest paid on a home loan for a self-occupied property. A let-out (rented) property follows different rules under the Income Tax Act, where the interest deduction is not capped at ₹2,00,000 in the same way, though the resulting loss that can be set off against other income in a year is limited. This calculator does not model let-out property interest — if that applies to you, treat the Section 24(b) figure here as a self-occupied-property estimate only.
