If the Paycheck Stops

The Surprise Hit

Compare cash, credit, or a mix before you choose how to handle it.

Get answers on:

  • Cash left

  • Buffer risk

Example result

Comfortable or Stretched

When you're eyeing a new place to live

What if this home costs 30% more than you planned?

See whether this home's monthly cost leaves room to breathe, compare it against a second option, and stress-test what happens if costs run higher than planned.

Get answers on:

  • Affordability verdict
  • Home comparison
  • Cost stress test
  • Cushion months

Example result

Staying put leaves $1,762/mo — comfortable. The new home leaves $515 — stretched. Example run: $6,800/mo take-home, $1,938/mo to stay put, $3,185/mo for the new home.

Where You Land

When the month disappears on you

What if you looked at your month honestly?

Get answers on:

  • Monthly landing
  • Trim payoff
  • Reserves runway

Example result

The month lands at +$1,030 — room to move, once it has a job. Example run: $5,800/mo take-home, $2,570/mo bills, $1,400/mo flexible, $550/mo saved, $3,000/yr irregular.

When You Stop

When the date you stop is still up to you

What if you stopped sooner, later, or right on schedule?

See how stopping work sooner or later than planned changes your odds of meeting your spending target and what's typically left over.

Get answers on:

  • Odds by date
  • Median left over
  • Year by year

Example result

Among the 954 futures that reached all three dates: stopping sooner met the target 31% of the time, the planned date 59%, one more year 71%. Median $163,000 left on the planned date. Example run: single, age 61 in 2026, planning to stop working in 2 years — $760,000 saved (taxable, tax-deferred, and Roth), $68,000/yr spending target, $1,500/mo still saved, $2,600/mo Social Security at full retirement age 67, $16,000/yr pre-Medicare healthcare.

How Scenarios Work

Four steps from question to plan.

1

Pick a scenario

Start with the money question that feels most real right now.

2

Enter your numbers

No need for exact cents. Ballpark your income, bills, or debt amounts.

3

Compare the paths

See what each path actually costs and which one fits your real life.

4

Save your plan

Turn the path you pick into a plan summary you can come back to.

Start with the question that feels most real right now.

Pick one money question, add a few numbers, and see the tradeoffs in plain English.

Example result

What if the paycheck stopped for three months?

Runway4.2 mo
Monthly gap−$680

Trimming flexible spending by 15% buys about six more weeks.
