22,000 this year vs 18,000 last year = 22.2% growth rate. For savers, tracking annual growth spots problems early. A flat or declining savings balance despite a salary means lifestyle inflation is eating new income. Targeting 10-15% annual savings growth is aggressive; 5-10% is a solid baseline for most savers.
Run it with sensible defaults
Using current savings of 22,000, last year's savings of 18,000, the calculation works out to 22.22%. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Current Savings and Last Year's Savings — do not pull with equal force. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
How the math works
Percentage change formula. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Turning the result into a plan
A projection is just a starting point. The real work is setting the monthly amount aside automatically so the saving happens before you can spend it. Most people who hit savings goals set up a standing order on payday; most who miss them rely on willpower at month-end.
What this doesn't capture
The calculation assumes a steady savings rate and a stable interest rate. Real saving journeys include emergencies, windfalls, and rate changes — especially in easy-access products. The figure is a direction of travel, not a guarantee.
Related calculations worth running
Plans get firmer when you triangulate. Alongside this one, the annual net worth tracker, the savings rate calculator, and the high yield savings calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.
