Most tools stop at one number

A runway calculator tells you when the money runs out. It doesn't tell you what to do about it.

Your runway depends on decisions

Extra mortgage payments, retirement contributions, food budget — these change your runway by months or years. A single burn rate ignores all of that.

Disruption is also an opportunity

Could you pay off your mortgage 8 years early? Max your 401(k) to the IRS limit? You can't answer those questions with a burn rate calculator.

Your numbers should persist

One-shot calculators reset every visit. Your financial picture is a living document — not a form you fill out again next week.

The complete financial picture

Six tools in one — all built around your actual numbers, all private, all in one place.

Runway + Zero Date

Your exact runway in days, weeks, and months — with a specific calendar date when savings hit zero. Urgency colour-coding so you know how much time you actually have to act.

Free — no account needed

Mortgage Optimizer

Full amortization with extra payment scenarios. See exactly how many years you cut off your payoff date and how much interest you save.

Pro

Investment Projections

401(k), IRA, and brokerage balances at 60, 65, and 67 — with employer match, multiple contribution scenarios, and tax-aware estimates.

Pro

Live Budget Cascade

Salary flows through housing → savings → food → expenses → remaining, updating live. See the waterfall in real time as you adjust any number.

Pro

Minimum Income Target

What's the lowest gross salary you can survive on? Calculated across health insurance premium tiers so you know your floor before any negotiation.

Pro

Annual Expense Set-Aside

Car registration, insurance renewals, home maintenance — enter them once as annual costs and see exactly how much to hold back each month so nothing blindsides you.
