Transparent calculations

Methodology

BeforeLeap uses deterministic calculations: the same valid assumptions produce the same result. The tool shows its inputs, keeps scenarios separate from the current state, and does not create a safety score.

What enters the runway model

Transition funds begin with liquid savings after the protected reserve is excluded, then include entered severance and other available cash. The protected reserve remains visible but is not treated as money the plan may consume.

Monthly spending is compared with reliable recurring income. Temporary income applies only for its entered duration, so the model can reflect a later increase in monthly outflow when that income ends.

Runway, targets, and timing

The engine models the spendable balance month by month. Runway is the time that balance supports positive net outflow under the assumptions entered. If reliable recurring income covers spending, the result is shown as ongoing rather than as a fabricated number of months.

A selected three-, six-, nine-, or twelve-month target is used to estimate the required funding level and any current gap. When the entered savings pace can close that gap, the tool estimates the minimum target month. That minimum is distinct from a later exit date the user may deliberately choose as a plan.

Scenarios and target solvers

Quit-now and waiting scenarios use the same underlying model. Waiting changes transition funds by the signed monthly savings pace, so a negative pace can reduce funds rather than incorrectly improving the outcome.

Target solvers change one variable at a time—starting savings, spending, reliable recurring income, or waiting time—while holding the other assumptions constant. They are mathematical comparisons, not recommendations.

Plans, privacy, and limitations

Selecting a plan does not change the current-state result. The chosen scenario is recalculated whenever valid assumptions change. Its three-page PDF is generated locally in the browser and distinguishes minimum target timing from chosen exit timing.

Results depend entirely on entered assumptions and intentionally omit taxes, investment returns, unemployment eligibility, job-market probability, and detailed category budgeting. The tool does not determine whether leaving a job is safe or appropriate and is not a substitute for professional advice.
