About AbacusHand
Free, accurate financial calculators built specifically for India — updated for FY 2025-26.
Why AbacusHand Exists
If you have ever typed “home loan EMI calculator” into Google, you know the problem: dozens of tools give you slightly different answers, most haven't been updated since the last tax revision, and none of them explain the formula they're using. For a decision as important as a ₹50 lakh loan or a 20-year SIP, that's not good enough. AbacusHand was built out of that exact frustration — the belief that every Indian, whether a salaried employee planning a home purchase or a small business owner calculating GST, deserves calculation tools that are honest, accurate, and up to date.
Our Mission
Our mission is to make every Indian financially empowered — not by selling products, taking commissions, or hiding results behind a paywall, but by giving everyone free, instant access to the same calculation tools that banks and chartered accountants use internally. From EMI planning to SIP projections, income tax under both old and new regimes to GST for businesses, AbacusHand exists to put clarity in your hands before you walk into any financial conversation.
What Makes Us Different
- India-specific, always: Every calculator is built for Indian regulations — RBI lending norms, SEBI rules, IT Act slabs, GST rates. No generic global tools repackaged for India.
- 67 calculators in one place: From basic EMI and FD to complex brokerage charges and SSY projections — the largest free calculator suite built for Indian personal finance.
- No signup, no login: Open any calculator and start immediately. We ask for nothing. No account, no email, no phone number.
- Instant results, zero delay: Results update in real time as you move sliders. No "Calculate" button to press, no page reload.
- Privacy-first — your numbers stay with you: Every calculation runs entirely inside your browser. Your financial data never touches our servers. We store nothing.
- Constantly updated: Updated after every Union Budget, quarterly government rate notifications, and any RBI/SEBI policy change affecting calculations.
How Our Calculators Work
Every calculator on AbacusHand is built using the standard formulas published by RBI, SEBI, the Income Tax Department, and other Indian government bodies. We cross-verify our logic against official circulars, published CA textbooks, and real bank sanction letters. No assumptions, no approximations beyond what the original formula specifies. Our calculators are updated for FY 2025-26, including the revised income tax slabs from Union Budget 2025, current PPF and SSY interest rates, and the latest GST notification rates.
Our Commitment to Accuracy
We don't ask you to take our accuracy on faith. Every calculator page on AbacusHand shows the exact formula being used, explains each variable, and includes a worked numerical example you can verify by hand or against your bank's statement. If you ever spot a discrepancy between our result and an official figure from your bank or the income tax portal, we want to know — and we will investigate and fix it within 48 hours. Accuracy is non-negotiable on a YMYL (Your Money or Your Life) platform.
