Small things I built because I wanted them.

Each one started as a spreadsheet I was tired of reopening. They run in your browser, they are free, and none of them will ask you to make an account.

Personal finance

Coast FIRE Calculator

Find the point where your savings can carry themselves to retirement without another dollar from you. Handles multiple accounts, adjusts for inflation, and shows the year you cross the line.

More on the way. If there is something you keep doing by hand in a spreadsheet, tell me and I will probably build it.
