The Foundation of Trust
At InterCalculator, accuracy is not a goal, it is our standard. Since our founding in 2025, we have committed to a “verification-first” model. We recognize that our users rely on us for significant life decisions, from financial planning to health tracking. This is how we ensure every number you see is one you can trust.
Our 4-Step Verification Method
Step 1: Authoritative Sourcing
We do not rely on second-hand information. Our developers, led by Haris Farooq and Ali Ejaz, source formulas directly from:
-
Government Agencies: (e.g., IRS, CDC, NHS, NIST).
-
Academic Institutions: Peer-reviewed research and standardized textbooks.
-
Industry Standards: Global financial regulations and scientific benchmarks.
Step 2: Technical Logic & Development
Once a formula is validated, our team builds a custom calculation engine. This phase includes “hard-coding” the logic to ensure that the tool handles variables (like compounding interest or metric-to-imperial conversions) with absolute precision.
Step 3: Expert Peer Review
In high-stakes categories like Finance or Health, we consult with subject matter experts. This ensures that our tools don’t just “do the math,” but also follow current industry best practices and legal standards.
Step 4: Stress Testing & Edge Cases
Before any tool goes live, it is subjected to a battery of tests using real-world datasets and extreme values. We compare our outputs against manual calculations and legacy benchmarks to ensure zero margin of error.
Ongoing Maintenance & Updates
-
Scheduled Audits: Every tool is reviewed every 6–12 months to ensure it remains aligned with any changes in laws or scientific standards.
-
Event-Driven Updates: If a tax law changes or a health guideline is updated, our team prioritizes an immediate update to the affected tool.
-
Community Reporting: We maintain a transparent feedback loop. Every user report of a potential calculation error is investigated by our technical lead within 48 hours from our contact page.
Our Commitment to You
When you see the “Accuracy Reviewed” badge on an InterCalculator tool, you are seeing the result of hours of research, expert consultation, and technical testing. We are committed to remaining the most transparent and reliable calculation platform on the web.
