Why Trust ArthPilot?
Built specifically for the Indian financial ecosystem — from tax slabs to PF rules. Every number is sourced, verified, and kept current.
Verified Formulas
Every calculator uses formulas sourced from official government notifications, the Income Tax Act, and RBI guidelines — not approximations.
Updated for FY 2026-27
Tax slabs, PPF rates, gratuity limits, and standard deductions are reviewed and updated every financial year.
No Data Stored
All calculations happen in your browser. We never store your income, salary, or investment details on any server.
Independently Reviewed
Each calculator is cross-checked against official examples and sample calculations before publication.
Editorial Standards
We hold our articles and calculators to the same standard you would expect from a financial advisor.
Source-First Writing
Every claim in our articles links to the official source — the Income Tax Department, RBI, or the Ministry of Finance.
Unbiased Comparisons
We do not sell financial products or earn commissions. Our comparisons are based on data, not affiliate relationships.
Regular Reviews
Articles are reviewed at least once a year and whenever a rule changes. The last review date is shown on every article.
Plain-Language Explanations
We translate legal and financial jargon into language a non-finance person can understand and act on.
Calculation Methodology
Every result you see follows a four-step process — from official source to your screen.
Source the Official Rule
We start from the primary source — the Finance Act, RBI circular, or scheme notification — to get the exact formula.
Build the Calculation
The formula is implemented in code with the same slab boundaries, rounding rules, and exemptions the law specifies.
Cross-Check with Examples
We verify each calculator against official sample calculations and edge cases like rebate limits and surcharge thresholds.
Publish and Monitor
After publication, we track regulatory changes and update the calculator the moment a new rule takes effect.
