Savings Goal Timeline Calculator Guide
Model a goal with steady contributions and optional compounding to get an illustrative time-to-goal or a “what to save each period” number. This page walks through the inputs, what the outputs show, and a few quick scenarios you can try.

Start with the calculator
Test your own goal in the Savings Goal Timeline Calculator to see an estimated timeline or an illustrative contribution-per-period figure.
Open the Savings Goal Timeline CalculatorQuick answer
The calculator gives you two quick reads: roughly how long it could take to hit your goal, or—if you set a deadline—how much to save each week or month to stay on track. Changing your contribution size, how often you add money, the deadline, or any rate assumption moves the result most.
- Outputs: an estimated time-to-goal and balance-by-date projection.
- Most sensitive inputs: contribution amount, how often you save, goal deadline, and any rate assumption.
- See rate notes and inflation context: interest/rate assumptions and inflation and savings goal timelines.

What this calculator is for
- Emergency buffer goals (generic) — map a target amount over a chosen time horizon.
- Sinking funds like car repairs, a holiday, or an annual insurance renewal.
- Medium-term goals such as a rental deposit or education fees where you want a month-by-month track.
- “Catch-up” planning after missing months, to see how extra contributions affect the timeline.

Inputs explained
Goal amount
The total you want to reach. Example: £1,500 for a holiday, including travel and spending money.
Common mistake: skipping small extras (like transfers or tips) so the target is too low.
Starting balance
What you already have set aside. Example: £300 already in a savings pot.
Common mistake: rolling this into your first contribution instead of entering it separately.
Contribution amount
What you plan to add each period. Example: £40 every week.
Common mistake: typing a monthly number when the frequency is set to weekly (or the other way round).
Contribution frequency
How often you add money: weekly, biweekly, or monthly. Example: £150 monthly on payday.
Common mistake: changing frequency later without resizing the amount, which shifts the totals.
Optional interest/return assumption
An illustrative annual rate if the pot earns interest. Example: 2% yearly for a simple savings account equivalent.
Common mistake: entering “5” when the field expects 0.05. See interest/rate assumptions.
Time horizon or end date
The deadline you’re aiming for. Example: 10 months from now to cover a yearly expense.
Common mistake: picking a short horizon without checking whether the contribution looks realistic.
Outputs explained
- Estimated time to reach the goal based on your inputs.
- A balance-by-date timeline that shows how contributions and any growth stack over time.
- Contribution vs growth breakdown if interest is included, so you can see what comes from deposits versus illustrative returns.

Example walkthroughs
Example A: simple sinking fund
Goal £1,200 in 12 months. Starting £0. Contribution £25 per week. Rate 0–1% (illustrative). You see a steady climb toward the target, with interest barely moving the needle.
Try it in the calculatorExample B: medium goal with a head start
Goal £10,000. Starting £2,000. Contribution £200 per month. Rate 2–4% (illustrative). An existing balance shortens the timeline, and a higher rate nudges the end date forward a little.
Try it in the calculatorExample C: time-to-goal comparison
Same goal. Compare £150 per month versus £250 per month. The higher contribution pulls the timeline in by several months; the lower option takes longer and might overshoot a fixed deadline.

Choosing an interest/rate assumption
Rates vary by provider and account type. Use a cautious figure and keep units consistent with the calculator. Read more in interest/rate assumptions for savings goals.
Remember inflation
Inflation can erode future purchasing power. Some people test a “real” view by adjusting the rate downward. See inflation and savings goal timelines.
Common mistakes
- Entering 5 instead of 0.05 when a decimal rate is expected.
- Mixing weekly and monthly numbers when the frequency is set differently.
- Forgetting irregular income weeks or months when planning contributions.
- Treating the projected timeline as guaranteed rather than illustrative.
