Money Rule Tools
Simple finance rules. Clear calculators. Real-world answers.
Money Rule Tools helps you understand how financial rules actually work — from paychecks and taxes to loans and mortgages — using focused tools and plain-language explanations.
Instead of generic calculators, we build rule-based micro tools that reflect real situations people deal with every day.

Why Money Rule Tools Is Different
Most financial tools show you a number — and stop there.
We believe numbers only make sense when you understand the rule behind them.
That’s why every tool on Money Rule Tools is built to:
- Focus on one specific problem
- Clearly state assumptions
- Explain how the result is calculated
- Include real-world examples
This makes our tools easier to trust, reuse, and bookmark.
Built for Clarity & Accuracy
Our tools are based on commonly used financial rules and publicly available guidelines. While we aim to keep everything accurate and up to date, financial rules can vary by location, employer, and personal situation.
Money Rule Tools is intended for educational and informational purposes only, not as personalized financial advice.
Free to Use
All tools on Money Rule Tools are free to access.
To support ongoing maintenance and improvements, we may display advertising on some pages. Advertising does not affect how our tools work or the results they provide.
