Quick answer
Find your target fund.
Subtract what you already have saved.
Divide the gap by your monthly savings capacity.
The timeline formula
gap = target_fund − current_savings
months_needed ≈ gap ÷ monthly_savings_capacityIf the gap is zero or negative, you are at or above target. Rounding can add or remove a month because the planner counts whole months when showing a date.
What changes the timeline
| Lever | If it increases | What happens | Example change |
|---|---|---|---|
| Monthly expenses | Higher | Target fund goes up; gap and months can rise. | Expenses from $2,200 to $2,500 |
| Months of coverage | Higher | Target multiplies up; timeline can stretch. | Months from 4 to 6 |
| Current savings | Higher | Gap shrinks; months can drop. | Savings from $1,000 to $2,000 |
| Monthly savings capacity | Higher | Gap closes faster; months can shorten. | Contributions from $250 to $400 |
Why the completion date is an estimate
- Contributions can vary month to month.
- Expenses can change after new bills or price shifts.
- One-time deposits or withdrawals shift the gap.
- Rounding and partial months affect the displayed date.
Rerun after any material change to keep the timeline current.
Three worked examples
| Example | Monthly expenses | Months target | Target fund | Current savings | Monthly savings | Estimated months |
|---|---|---|---|---|---|---|
| A: Some savings, steady adds | $2,000 | 5 | $10,000 | $3,000 | $400 | ≈ 17.5 |
| B: Higher expenses, smaller adds | $3,200 | 6 | $19,200 | $1,000 | $300 | ≈ 60.7 |
| C: Boost savings or trim expenses | $2,800 → $2,600 | 6 | $16,800 → $15,600 | $2,000 | $500 → $600 | ≈ 29.6 → 22.7 |
A: A smaller gap and steady adds keep the timeline moderate. B: High expenses and lower contributions stretch the runway. C: Cutting $200 of expenses and adding $100 per month shortens the estimate meaningfully.
Using scenarios to speed up planning
Save a baseline scenario, then run a higher contribution scenario, a lower expenses scenario, and a higher months target scenario. Compare shortfall and timeline side by side in the planner. For steps, see the how-to guide.

FAQ preview
Why did my timeline change?
Updates to expenses, coverage months, savings, or contributions change the gap and months needed.
What if my monthly savings varies?
Rerun with new amounts; variable contributions shift the estimate.
What if I have a surplus?
If current savings exceed the target, the planner shows a surplus and the timeline may be zero.
How often should I rerun?
Rerun after bills change, after one-time deposits or withdrawals, or when your income shifts.
Can I export results?
Yes. Export summaries and review the Privacy Policy for data handling.
Is this financial advice?
No. Timelines are estimates and depend on your inputs.
