Know exactly how long
your money will last.

Enter your savings, monthly expenses, and housing costs. Get a specific calendar date — not a vague "about a year" — when your money runs out. Then see how each scenario shifts it.

With income

Model any income change — a new role, a raise, or a side gig — and see how quickly your financial pressure drops.

With unemployment

Benefits extend your runway. See the new zero date with unemployment factored in — and by exactly how many months it buys you.

Burn only

Income stops entirely — the worst case. Know exactly how many months you have before the account hits zero.

Most tools give you one number.
One number isn't enough.

The problem

Your runway depends on decisions you're making right now.

Extra mortgage payments, retirement contributions, food budget — each one changes your zero date by months or years. A burn rate calculator ignores all of that.

The opportunity

Disruption is also a window.

Could you pay off your mortgage 8 years early? Max your 401(k) to the IRS limit? Survive on less than your current salary? You can't answer those with a simple calculator.

The persistence

Your financial picture is a living document.

One-shot calculators reset every visit. Your numbers should persist — updated as your situation changes, not re-entered from scratch next week.
