Catch-up planning
How to Catch Up on a Savings Goal (3 Levers)
Falling behind is common. You can model catch-up by adjusting time, contributions, or assumptions, then compare the trade-offs in the calculator without pressure or guesswork.

Lever 1: Time — extend the deadline to lower the required monthly amount in the model.
Lever 2: Contributions — save a bit more or more often to speed progress.
Lever 3: Assumptions — adding a rate can change projections, but it’s uncertain and not guaranteed.
Goal costs can move: inflation and savings goal timelines.

The 3 levers explained
Time
Extending the deadline reduces the required monthly amount in the model but takes longer to finish.
Contributions
Increasing the amount or frequency speeds modeled progress; the trade-off is cashflow pressure.
Assumptions (optional)
Adding a rate can change projections, but outcomes aren’t guaranteed. Use low/base scenarios rather than relying on one optimistic number.
Lever trade-offs
| Lever | What it changes | Typical downside |
|---|---|---|
| Time | More months to reach the goal | Goal takes longer |
| Contributions | Higher saving speed | Cashflow pressure |
| Assumptions | Projected growth (modeled) | Uncertainty; not guaranteed |
Example 1: Behind on a near-term goal
Goal £1,200 with 6 months left; current balance £300; original plan £150/month. Catch-up options (illustrative): add a one-off top-up and keep £150/month; or increase the monthly amount modestly for the remaining 6 months; or extend the deadline by 1–2 months. Run each as its own scenario in the calculator.

Example 2: Longer goal with inflation awareness
Goal today £10,000 over 5 years; current balance £2,000; contribution £200/month. Catch-up options: increase the contribution, extend the timeline, or add a conservative rate assumption and run low/base scenarios (not promises). Also stress-test an inflation-adjusted goal amount to see how the target could move.

How to model catch-up in the calculator
- Run your baseline plan (a 0% baseline is a clean starting point).
- Scenario A: extend the timeline, keep contributions the same.
- Scenario B: increase contributions, keep the timeline the same.
- Scenario C: add a one-off top-up (increase starting balance) if relevant.
- Optional: add a low/base assumption and compare. Keep one change at a time.

If you keep falling behind
- Reduce complexity: fewer active goals can make progress clearer.
- Use minimum vs stretch contributions to handle uneven months.
- Focus on consistency over perfection; rerun plans as life changes.
Reset the monthly view: how much to save per month.
Common mistakes
- Changing multiple inputs at once (hard to see what helped).
- Relying on an optimistic rate assumption to “solve” the gap.
- Ignoring inflation for long goals.
- Treating delays as failure instead of updating the plan.
FAQ
What’s the fastest way to catch up on a savings goal?
Model a one-off top-up vs a higher contribution and see which fits your cashflow.
Should I increase contributions or extend the deadline?
Test both separately. One may be gentler on cashflow; the other finishes sooner.
Is a one-off deposit the best catch-up method?
It’s one option. If a lump sum isn’t available, a temporary boost or timeline extension can also work.
Should I include an interest rate assumption?
Only as a scenario input. It’s not guaranteed. Run 0% plus low/base to see a range.
What if I missed multiple months?
Remove those contributions in a scenario, then test higher contributions or a longer timeline.
Does inflation change the goal amount?
It can for long goals. See inflation and savings goal timelines.
Are calculator results guaranteed?
No. They’re based on inputs and assumptions.
Where can I find help choosing a monthly contribution?
Start with how much to save per month.
Where can I learn about missed months?
Run 3 catch-up scenarios
Baseline, higher contribution or timeline extension, and one-off top-up. Pick the trade-off you can live with.
