Why PaisaTools?
Most calculator sites are slow, stuffed with popups, and hide the formula. PaisaTools is different: every calculator loads instantly, works on any phone, shows its exact formula, and uses the latest official rates — income tax slabs for FY 2026-27, PPF at 7.1%, and bank-style quarterly compounding for FDs.
Built on official numbers
Tax slabs follow the Income Tax Act as amended by Budget 2025 and retained in Budget 2026 (₹75,000 standard deduction, Section 87A rebate up to ₹12 lakh income under the new regime). Small savings rates match the Ministry of Finance quarterly notification.
