Disclaimer
Every figure Calculix produces is an estimate based on the numbers you enter and the rates configured on this site. This page sets out, honestly, where those estimates stop being reliable.
1. Not professional advice
Nothing here is tax, legal, investment or accounting advice, and no relationship of adviser and client is created by using this site. The calculators model common situations. They do not know your facts, your contracts, your history or your intentions.
Have anything material reviewed by a qualified professional before you act on it.
2. Tax calculators
Income tax slabs, rebates, surcharge thresholds, deduction limits and cess change with each Finance Act, sometimes retrospectively. Professional tax varies by state. Your employer's salary structure may differ from the standard model used here.
These tools do not model set-off or carry-forward of losses, relief under section 89 for arrears, foreign tax credit, clubbing provisions, presumptive scheme interactions beyond those stated, additional depreciation under section 32(1)(iia), or transfer pricing. Capital gains on property acquired before 23 July 2024 may qualify for an alternative computation that must be compared manually.
Treat any tax figure as an indication for planning, never as a filing.
3. GST calculators
The correct GST rate depends on the HSN or SAC classification of what you supply, and classification is a question of law, not arithmetic. Late fees, interest rates and caps change by notification, and amnesty schemes are not modelled. Always confirm the figure the GST portal itself demands before paying.
4. Seller and platform calculators
Marketplace referral fees, closing fees, shipping and fulfilment charges vary by category, price band, weight, dimension and fulfilment channel, and are revised by the platforms without notice. Check your current rate card in Seller Central or the equivalent.
5. Investment and savings calculators
SIP, lumpsum, FD, RD and PPF projections assume a constant rate of return for the whole period. No market delivers that. Real returns swing either side of the average, and the order in which they arrive materially changes the outcome, especially near the end of a long period. Small savings rates are notified quarterly by the government and will not stay fixed for fifteen years. Expense ratios, exit loads and taxes are not modelled unless stated.
Past performance is not a guide to future returns. Nothing here is a recommendation to buy or sell any financial product.
6. Loan calculators
EMI figures assume the rate stays fixed. Most home loans are linked to an external benchmark and reprice as it moves. Processing fees, insurance sold alongside the loan and other charges vary by lender.
7. Advertising revenue calculators
Earnings estimates depend on niche, country, season, ad demand and network policy. They are projections from your own inputs, not a forecast of what you will actually earn.
8. Rates configured on this site
Slabs, rates, thresholds and limits are stored as editable settings so they can be corrected quickly when the law changes. We update them promptly, but there may be a gap between a change taking effect and this site reflecting it. If a figure looks wrong to you, it may be — tell us at info@calculix.in and we will check it the same day.
9. Liability
Dream Blend Solutions Private Limited accepts no liability for any decision taken on the basis of a calculation made here. See our Terms and Conditions for the full position.
