Support this project
This calculator is free, has no sign-up, and never sees your numbers — and we'd like to keep it that way. If it helped you plan with a little more confidence, here are three simple ways to help it reach more people. Every one of them makes a real difference.
Share it with someone
The single most helpful thing you can do: post a link where friends, family, or colleagues will see it. One share often reaches exactly the person who's been putting off this question.
Link to it from your website
If you write a blog, run a forum, or maintain a resources page, a link helps other people discover the tool — and helps search engines trust it. Copy and paste this snippet anywhere on your site:
Make a small donation
Hosting and development have real costs. If the calculator saved you time or gave you clarity — and only if you comfortably can — a small donation helps keep it free and private for everyone.
