What to look at first

Your runway gap

You are $5,600 short of your 6-month target. At the current savings pace, the target is approximately 4 months away.

The whole picture

What this means

Your current transition funds support 4.2 months of runway against your 6-month target.

The starting-funds gap is $5,600.

The one-variable options below show how savings, spending, income, or time change that gap.

At the current savings pace, the target is approximately 4 months away.

Transparent by design

How this calculation works

Your protected reserve stays outside spendable transition funds. The deterministic engine models the remaining balance month by month, and temporary income stops after the duration entered.

Waiting scenarios use your current monthly savings pace. This tool helps compare assumptions; it does not determine whether leaving a job is personally or professionally safe.

What this tool answers

A focused view of your job-exit runway

Runway and protected reserve

Runway is the time your spendable transition funds support the entered post-exit outflow. Protected reserve stays visible but is excluded from the money both chart lines and scenarios may use.

Waiting scenarios

Quit now, Wait 3, Wait 6, and the custom sandbox use the same assumptions. Waiting applies the signed savings pace, so it can add or reduce transition funds.

Ways to reach a target

The four target solvers each change one variable while holding the others constant. They are transparent comparisons, not recommendations or a readiness score.

Your selected plan

The local three-page PDF records the chosen scenario, current and projected runway, assumptions, checkpoints, minimum target timing, and chosen exit timing.

Recalculate when the assumptions change

Revisit the plan if spending, reliable income, savings, protected reserve, or intended exit timing changes. The calculator is a planning aid based on entered estimates; it does not account for taxes, investment returns, unemployment eligibility, or job-market outcomes, and it does not determine whether resigning is safe.
