👋 Meet the Team
Hi, I'm Amanda Reeds — founder and Editor-in-Chief of Ace Calculator. I hold a B.S. in Mathematics and have spent 8+ years in web development and data-driven content. I started this platform after growing frustrated with slow, cluttered, ad-saturated calculator sites that buried the answer in noise.
My role covers overall editorial direction, formula sourcing, and quality standards. Every calculator published on this site ultimately goes through my review before it goes live.
✉️ support@acecalculator.comJames Carter joined Ace Calculator in 2022 as Senior Content Editor. With a background in financial analysis and technical writing, James oversees our finance and health calculator descriptions, ensuring every explanation is accurate, jargon-free, and genuinely useful to everyday users.
Sehrish Sattar is the lead developer responsible for building and maintaining every calculator on the platform. She brings 6 years of front-end and JavaScript development experience and personally stress-tests each tool against reference data sources before it reaches users.
📖 Our Story & History
Ace Calculator was founded in 2021 by Amanda Reeds after experiencing the same frustration that millions of users share — calculator websites that are slow, packed with ads, and hard to trust. The solution was a clean, fast, free platform where anyone could get an instant, accurate answer.
Site Launched
Ace Calculator goes live with 12 core calculators covering basic math, BMI, and simple loan calculations. Operated by Web Studio London, registered in the United Kingdom.

50+ Calculators Milestone
The library passes 50 free calculators. Each tool now includes a sourcing footnote linking to the academic or governmental reference used for its underlying formula.
Ongoing — Accuracy & Transparency Initiative
We publish this updated About page with full publisher identity, named team members, and a formal editorial policy — because our users deserve to know exactly who is behind the numbers they rely on.
📋 Editorial & Accuracy Policy
Because Ace Calculator covers finance and health topics that fall under Google's YMYL (Your Money or Your Life) standards, we hold ourselves to a strict editorial process. Here is exactly how every calculator is researched, built, and maintained:
Formula Sourcing from Primary References
Every formula is sourced from peer-reviewed academic publications, U.S. government agencies (e.g. CDC, IRS, Federal Reserve), or established professional standards bodies (e.g. ACOG for health calculators, CFPB for financial tools). Secondary sources are never used alone.
Independent Cross-Testing
Each calculator is tested against at least two independent reference tools — including official government calculators where available — using a standardized set of 10+ edge-case inputs before publication.
Human Editorial Review
All calculator descriptions, methodology notes, and result explanations are written by a named team member and reviewed by the Editor-in-Chief before going live. No content is auto-generated and published without human review.
Scheduled Review Cycle
Finance and health calculators are reviewed on a 6-month cycle — or immediately when a governing standard changes (e.g. IRS tax brackets, CDC BMI guidelines). The last-reviewed date is shown on each calculator page.
Error Reporting & Correction
Users can report suspected errors directly to support@acecalculator.com. Confirmed errors are corrected within 48 hours and noted in a correction log on the affected page.
"We are not a nameless content farm. Every number on this site has a person's name attached to it — and that person stands behind it."
