Emergency Fund Calculator

An emergency fund is the difference between a setback and a spiral. This tool helps you size yours honestly: what your real monthly expenses are, how many months of buffer feels right for your life, and — given what you can actually save each month — when you'll get there. No moralising, just numbers.

What it does
  • Target buffer in months (you choose)
  • Current savings + monthly save rate
  • Months until fully funded
  • Visual progress bar
  • Honest framing — no guilt, no shame

A widely-cited standard: 3–6 months covers most non-catastrophic life events.

A note on the numbers above: An emergency fund isn't about reaching some "correct" amount — it's about reaching the amount that lets you sleep. If 1 month is what you can manage right now, that's the right target right now. The next 1 comes after that.
