Tools Policy

Last Updated: October 2, 2026

Requirement Calculator provides online calculators and tools designed to simplify calculations, estimates, comparisons, and planning tasks.

This Tools Policy explains how our tools are designed and how users should interpret their results.

Purpose of Our Tools

Our tools are designed to provide convenient calculations and estimates based on information entered by the user.

They are intended to support planning, learning, research, and general decision-making.

How Calculations Work

Each calculator may use its own formulas, assumptions, variables, and calculation methods.

Where practical, we explain the methodology used by a tool so users can understand how the result is produced.

For example, the Requirement Calculator uses feature counts and complexity multipliers to estimate project effort and then uses team capacity to estimate project duration.

User Inputs

The accuracy of a result depends partly on the quality of the information entered.

Users should provide realistic and relevant inputs and review the assumptions associated with each tool.

Incorrect, incomplete, outdated, or unrealistic inputs may produce misleading results.

Estimates Are Not Guarantees

Many of our tools produce estimates rather than guaranteed outcomes.

Actual results may differ because of changes in circumstances, individual conditions, technical issues, scope changes, human factors, or other factors.

Users should not treat a calculator result as a promise or guaranteed outcome.

Tool Updates

We may modify formulas, assumptions, design, functionality, or inputs when we determine that an improvement is appropriate.

As a result, the same inputs may potentially produce different results after a calculator has been updated.

Technical Availability

We aim to keep our tools available and functional, but we cannot guarantee uninterrupted availability or that every tool will always be free from errors or technical issues.

User Responsibility

Users are responsible for evaluating whether a tool is appropriate for their particular situation.

For important decisions, we recommend checking the result against relevant professional advice, historical data, documentation, or other appropriate sources.

Reporting a Tool Issue

If you find a calculation issue, broken feature, incorrect formula, or unclear explanation, please contact:

info@requirementcalculator.com

Please include the calculator name and, where possible, the inputs that produced the issue.
