Everything on Quanticed is built to be accurate, transparent, and genuinely useful for understanding money — not just for ranking in a search engine. This page sets out the standards we hold our calculators and content to, so you can judge for yourself how much to trust what you read here.
How a calculator is built
Each calculator goes through the same disciplined process:
- Define the formula. We start from the established, canonical formula for the calculation — drawn from standard finance and mathematics, not reverse-engineered from other websites.
- Implement it in an isolated engine. The maths lives in a framework-agnostic calculation engine, separate from the user interface, so the logic is easy to read, test, and verify.
- Cover it with automated tests. Each engine ships with a suite of unit tests that pin its output to known-correct values — worked examples, textbook results, and boundary cases such as zero or negative inputs. A calculation can't change without the tests confirming it still matches the expected answer.
- Explain it on the page. Every tool is published alongside a plain-English explanation of the concept, the formula written out, worked context, and frequently asked questions.
Accuracy and assumptions
Many financial calculations depend on conventions — how often interest compounds, which day-count basis a bond uses, whether a model assumes constant volatility. We make these assumptions explicit on each page rather than hiding them, because the same inputs can produce different answers under different conventions, and you deserve to know which one a result reflects.
Where a calculator uses a simplified model — as our educational equities and derivatives tools do — we say so plainly. Those tools illustrate how the formulas behave; they are not professional-grade systems and do not use live market data.
Sourcing
Our formulas and definitions are grounded in widely accepted financial theory and standard references in mathematics, accounting, and finance. Where a concept has more than one common definition, we describe the variant we use. Tax-related tools reflect generally applicable rules and rates as described on each page; because tax law changes and varies by jurisdiction, we note when figures are illustrative and may not reflect the latest legislation.
Expert review
We are building a network of qualified financial professionals — including CFAs, CFPs, accountants, and finance academics — to review our calculators and explanations. When a tool or article has been reviewed, we credit the reviewer and the date of review so you can see who stands behind it. If you are a professional interested in reviewing our work, please see theabout page and get in touch.
Corrections
We want every number on the site to be right, and we treat errors seriously. If you believe a calculator or explanation is incorrect, pleasetell us with as much detail as you can. We investigate every report, fix confirmed errors promptly, and update the affected pages.
Independence
Quanticed's calculations are never influenced by commercial relationships. Results are not sponsored, and we do not adjust outputs to favour any product or partner. Any future advertising or affiliate content will be clearly labelled and kept separate from the tools themselves. For the limits of what our tools can do, please read ourdisclaimer.
