Free Financial Calculators for India
Income tax, EMI, SIP, GST and more — built for Indian rules and rupee formatting.
Last updated: 5 September 2026What India Calc is for
India Calc answers the money questions that come up in an ordinary Indian household — how much tax will actually be deducted from a ₹14,00,000 salary, what a ₹45,00,000 home loan costs over 20 years, whether a ₹5,000 monthly SIP is worth starting, and what the price of a service looks like before and after GST. Every tool runs in your browser, gives you a full breakdown rather than a single mystery number, and needs no sign-up.
We built it because most Indian calculators either bury the result behind a lead-capture form or quietly use last year's slabs. Ours state the assumptions on the page. If a number depends on something that changes — a slab, a GST rate, a filing deadline — we date it, and we tell you where the official version lives.
The tools are aimed at salaried employees, freelancers and small business owners who want a quick, honest estimate before a bigger decision: choosing a tax regime in April, comparing two home loan offers, deciding between a fixed deposit and an index fund SIP, or sanity-checking a GST invoice from a vendor.
Latest guides
Calculators give you a number. The guides explain what to do with it — written in plain English, with Indian rupee examples and current rules.
Quick reference for FY 2026-27
The Budget presented in February 2026 left the new-regime slabs untouched, so the rates below apply to both FY 2025-26 and FY 2026-27. The new regime is the default; you have to actively opt out to use the old one.
New regime income tax slabs
| Taxable income | Rate |
|---|---|
| Up to ₹4,00,000 | Nil |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Add 4% Health & Education cess on the tax computed. A salaried person or pensioner also gets a ₹75,000 standard deduction, and the rebate under section 87A wipes out up to ₹60,000 of tax when taxable income is ₹12,00,000 or less.
GST slabs after GST 2.0
The 56th GST Council meeting collapsed four main slabs into two, effective 22 September 2025. The 12% and 28% rates were removed for most goods and services.
| Rate | Typical coverage |
|---|---|
| 0% | Unbranded staples, fresh produce, individual life and health insurance premiums |
| 5% | Most packaged food, household essentials, small-ticket services |
| 18% | The standard rate — electronics, most services, restaurant and professional fees |
| 40% | De-merit goods: tobacco, pan masala, aerated and sugary drinks, luxury cars |
Two special rates survive outside this structure: 3% on gold and silver, and 0.25% on rough diamonds. Run a specific invoice through the GST calculator to split a gross amount into base price and tax.
How we keep the numbers right
A financial calculator is only useful if the rules behind it are current. Here is exactly how we maintain ours.
Where our figures come from
- Income tax slabs, rebates, deductions and filing deadlines — the Income Tax Department portal, the Finance Act as passed, and CBDT circulars.
- GST rates and exemptions — CBIC notifications and GST Council press releases, cross-checked against the GST portal.
- Interest rate context — the Reserve Bank of India for the repo rate and lending benchmarks. We never quote a specific bank's FD or home loan rate as fact, because those move weekly. Where a rate matters, we give a range and tell you to check your own bank.
Our update policy
- Budget day and Finance Act passage. Tax pages are reviewed within a week of the Union Budget and again when the Finance Act receives assent, since the two can differ.
- GST Council meetings. GST pages are checked after every Council meeting that changes rates.
- Quarterly sweep. Every calculator and guide is re-read at least once a quarter, whether or not anything changed, and the "last updated" date on the page reflects the real review date rather than a script.
Formulas are tested separately from the rules. Each calculator's output is checked against a hand-worked example and against at least one independent source before it goes live. If you find a number you can't reproduce, tell us the exact inputs on the contact page and we will either fix it or explain the assumption.

Popular questions
- Are the tax slabs on this site for FY 2025-26 or FY 2026-27?
- Both, because they are identical. The new-regime slabs introduced for FY 2025-26 were carried forward unchanged into FY 2026-27, so the same table applies to the return you file now and to the salary you are earning this year.
- How much can I earn before paying any income tax?
- Under the new regime, a salaried person or pensioner earning up to ₹12,75,000 gross pays nothing. That is ₹12,00,000 of taxable income, at which the section 87A rebate cancels the tax, plus the ₹75,000 standard deduction. Someone without salary income — a freelancer, say — gets the same rebate but no standard deduction, so their zero-tax ceiling is ₹12,00,000.
- Should I choose the old regime or the new one?
- Most salaried people below roughly ₹15,00,000 are better off in the new regime unless they have a large home-loan interest deduction. The old regime only overtakes it once your total deductions — 80C, 80D, HRA, home loan interest, NPS — are big enough to offset the lower rates. Our old vs new comparison tool works out the exact break-even for your numbers.
- Do you store the amounts I type into a calculator?
- No. Every calculation runs as JavaScript inside your browser. Your salary, loan amount or investment figure is never transmitted to us and never written to a server. There is no account to create and nothing for us to leak.
- Why did GST on my restaurant bill change?
- GST 2.0 took effect on 22 September 2025 and removed the 12% and 28% slabs for most items, leaving 0%, 5%, 18% and a 40% de-merit rate. Many goods moved down a slab. Our GST 2.0 guide lists the main reclassifications.
- Can I use these calculators for filing my actual return?
- Use them to estimate and to plan, not to file. They cover the common cases well but deliberately leave out surcharge on incomes above ₹50,00,000, capital gains treatment and business income adjustments. For the return itself, use the Income Tax Department's own utility or a qualified chartered accountant.
