Savings Runway Calculator: See exactly how long your savings will last

I built this after realizing most budget calculators want you to sign up, connect a bank account, or hand over an email before they'll tell you something simple: how many months will my savings actually last? So I stripped it down to just that. Three inputs, one answer, a chart showing the balance over time. No account, no data stored, nothing sent to a server — it all runs in your browser. It's free to use. If you want to take the next step and actually build out a full monthly budget, I also put together a more detailed Cash Flow and Budget Tracker template, linked on the page. Would love feedback on what else would make this more useful — more scenarios, an export option, something else entirely.
