Perma calculator — transparent math, no hallucinations
Published: 2026-05-27
The perma calculator does exact taxable calculations for permaculture / CSA projects. Every number has a public source or is directly measured.
What is real, what isn't

Removed from a previous version (no public source): "10% overhead", "0.5% value share", "€1 floor", "expertise minutes" formula, the word "commission" (legally inappropriate for donations). See .vitepress/calculator-data.json for the full audit record.
Why free
svilena.me is a public project. The calculators give accurate information for free to anyone who needs it. If your project is better-built because of them and you want to support the work, do it voluntarily — the suggested amount in the calculator is only a reference point, not an obligation.
