About SolveNook

SolveNook provides browser-based utilities for material planning, business arithmetic, energy estimates and finance illustrations. Our purpose is to make a practical task easier and show how the answer was reached.

SolveNook is operated by Renvoro Pty Ltd.

We publish the formulas, assumptions, worked examples and review date for each tool. We do not claim professional qualifications, product certifications or guaranteed savings. Estimates are not a substitute for measured supplier information or professional advice where needed.

How we maintain tools

Numeric engines use automated known-answer and boundary tests. Changes should update the method and relevant tests together. If you find a calculation that does not match its documented assumptions, report the issue.
