Thanks for your appreciation of SageMath! I find a lot of happiness in it too!

There used to be a donation button for donating to "The Sage Foundation", a foundation supporting SageMath which was operated by the University of Washington; however this foundation has been discontinued.

SageMath applying to become a sponsored project of NumFOCUS (or of its European equivalent, which is in the process of being created) is regularly discussed; this has not happened yet but I am sure it will become a reality in the not so distant future.

In the meantime, you could make a donation to one or several of the NumFOCUS-sponsored projects that underly SageMath, for example NumPy, Matplotlib, Jupyter, IPython, SymPy, Conda-Forge, MathJax... Or to other NumFOCUS-affiliated projects, for example Cython... Or to the Python Software Foundation.

The "14 USD/month" you refer to is probably a CoCalc plan; note that you can subscribe to it once in a while for just a month or two, if that is the kind of amount you want to spend.

Another way to help is to get Google Cloud starting credits and to set up some GitLab runners to help with the continuous development / continuous integration of SageMath. See the GitLab-CI page on the SageMath wiki.

Edit (2020-12).

There are now two easy ways to donate to the SageMath project.

via OpenCollective: https://opencollective.com/sage_math

Donations are tax deductible in the USA under IRC 501(c)(6).via GitHub Sponsors: https://github.com/sponsors/sagemath

or visit the SageMath page on GitHub and click the "Sponsor" button

If anybody would like to donate hardware, please get in touch with me.
