How AKCalc researches, builds, verifies, and maintains its calculators
Last updated: June 2026
This page describes the general methodology AKCalc uses to research, build, verify, and maintain its finance calculators. It is intended to help users understand how the calculators work, where the underlying rules come from, and what steps are taken to keep them reliable.
Each calculator on AKCalc may reference its own country-specific rules and sources. This methodology applies across the website while allowing each tool to follow the approach that is appropriate for its subject and jurisdiction.
When a new calculator is being developed, the first step is identifying the applicable rules for the country and topic. Research relies on authoritative primary sources wherever they are available and applicable. These may include:
Not every calculator draws on every type of source. The specific sources depend on what is published and applicable for the country and topic in question. Where authoritative primary sources are not available or do not cover the specific calculation, we use the best publicly available information and clearly indicate the basis.
The process for building calculator logic generally follows these steps:
The exact implementation details and internal logic vary by calculator. This description outlines the general approach rather than the specifics of any single tool.
Each calculator is accompanied by explanatory content written to help users understand:
Explanations are written in plain language and are reviewed alongside the calculator logic before publication.
Every country has its own:
Each calculator is researched individually using sources that are relevant to that country. A calculator for one jurisdiction should not be used as a substitute for a calculator designed for another. The methodology for each calculator reflects the rules and practices of its specific jurisdiction.
Wherever appropriate, calculators reference the authoritative sources used to build them. Examples of sources that may be referenced include:
The exact sources cited differ by calculator and jurisdiction. Where a specific source is referenced on a calculator page, users can consult it directly to verify the basis for the calculation.
AKCalc reviews its calculators when important official changes are identified. This includes changes such as:
When a verified change is identified, the relevant calculator is updated to reflect the new rules. AKCalc does not continuously monitor every jurisdiction in real time, and updates may take time depending on the availability and verification of source documents. Users should check the last-verified date shown on each calculator for an indication of its review status.
AKCalc calculators are designed to provide general informational assistance. They are not a substitute for professional financial, tax, legal, or accounting advice.
Results may differ from actual outcomes depending on individual circumstances, including but not limited to:
Users who require personalized advice should consult a qualified professional with knowledge of their specific situation.
Users who identify potential issues, outdated information, or errors in any calculator are encouraged to report them. Feedback can be submitted through the Contact page. Reported issues are reviewed and, where verified against the relevant sources, corrected in the affected calculator.
