Formula verification: All calculation formulas are cross-verified against official documentation from the relevant regulatory body. For example, EMI formula is verified against RBI guidelines, SIP formula against AMFI standards.
Rate updates: Rate-linked calculators draw from versioned JSON files in our codebase. When rates change, we update the JSON and trigger ISR revalidation — all tools automatically reflect the new rates within the hour.
Test coverage: Every calculation function has unit tests with expected values hand-calculated from official sources. We run these tests before every deployment.
No web scraping: We do not scrape bank websites, competitor tools, or government portals. All data comes from official public documents (PDFs, circulars, press releases).
IndiaUtils is built and maintained by the IndiaUtils Editorial Team. We are a team of engineers and finance professionals who believe that accurate financial tools should be accessible to every Indian, not just those who can afford a financial advisor.
