Terms of Use
Last updated: 2026-10-21
This is not financial advice.
The calculators on this site are arithmetic tools. They are not financial, investment, tax, legal, or accounting advice, and using them does not create a professional relationship of any kind. They cannot know your full circumstances, and their output is only as good as the assumptions you feed them.
Before acting on any result here, talk to a qualified professional who knows your actual situation.
By using iwilldecide.com, you agree to what follows. If you don't, please don't use the site.
What this site is
A set of free calculators for common financial and life decisions, plus written explanations of the reasoning behind them. Everything is offered for general informational purposes. Results are estimates based on the numbers and assumptions you enter, not predictions or financial advice.
Accuracy
Real effort goes into the formulas and the assumptions behind them — the methodology page documents them. But tax rules, rates, and regulations change, and models simplify. The content may be incomplete, out of date, or wrong. You use it at your own risk.
No warranty and no liability
This site is provided as-is, without warranty of any kind. To the fullest extent the law allows, the site and its operator are not liable for any loss or damage arising from your use of it, or from decisions you make based on it. That includes financial loss from a decision a calculator here informed.
Content and ownership
Unless stated otherwise, the content on this site belongs to its operator. Link to it and quote it with attribution freely; wholesale reproduction requires permission.
Links elsewhere
This site links to sites it does not control and is not responsible for their content or practices.
Changes
These terms may change. The date above says when they last did.
