About us
We build free, fast, independent financial calculators that show the whole picture — including inflation.
Why this calculator exists
Most SWP calculators answer one question: “What is left after N years?” But people planning a retirement income need to know more — whether their money lasts, what their income will really be worth after inflation, and how much they can safely withdraw. We built calculateswp.com to answer those questions in one place, for free, without an account or an app download.
What we stand for
- Transparent maths. Every formula is published on the methodology page, and every result can be checked in the downloadable schedule.
- Independence. We don’t sell funds or take commissions, and the calculator never nudges you towards a product.
- Privacy. Calculations run in your browser; we don’t collect what you type.
- Accessibility. Keyboard-friendly, readable in light and dark mode, and available in nine languages.
