Net Worth Milestone Calculator
Years to next wealth milestone.
Calculate years until reaching your next net worth milestone at current savings pace and expected return. Enter target net worth to see years to target.
What this tool does
This calculator estimates how many years it will take to reach a net worth target based on your current net worth, annual savings contributions, and expected investment return. The result shows the timeline to your milestone at your current savings pace and assumed growth rate. The calculation compounds your existing net worth and adds annual savings year by year until the target is reached. The time horizon is most sensitive to the gap between your current and target net worth, along with your annual savings amount and expected return rate. For example, a larger savings contribution or higher return assumption will shorten the timeline, while a bigger wealth gap extends it. This estimate assumes consistent annual savings and steady returns; actual results may vary based on market conditions, changes in savings behaviour, and economic factors. The output is for illustration purposes only.
Quick answer: with the default values, the result is 9.3 years (Years to Target). Adjust the values below for your own figures.

150,000 current, target 500,000, 20,000 annual savings, 6% return: 9.3 years. Changing any lever shifts the timeline. Savings rate dominates in the first half; return dominates in the second. Milestones (first 100k, first 250k, first 500k, first 1m) motivate consistent behaviour.
A worked example
With the defaults: current net worth of 150,000, target net worth of 500,000, annual savings of 20,000, expected return of 6%. The tool returns 9.3 years.
What moves the number most
The result responds to Current Net Worth, Target Net Worth, Annual Savings, and Expected Return.
The formula behind this
Year-by-year compound growth of current net worth plus annual savings. Stop when target reached.
What to calculate alongside this
One figure by itself is fragile. The wealth building rate calculator, the annual net worth tracker, and the frugal vs lifestyle inflation path calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool.
Which lever moves the date
Two levers move the milestone date and they dominate at different stages. Early on, contributions do most of the work, because the balance is small and growth has little to act on. Later the balance is large enough that returns contribute more each year than the contributions do. At the defaults, 150,000 growing at 6% with 20,000 added annually reaches 500,000 in about 9.3 years.
What the projection assumes
The projection assumes both the contribution and the return hold steady for the whole period, which no real portfolio does. It also works in nominal terms, so a target set today buys less by the time it is reached. Raising the target by expected inflation over the period gives a figure closer to constant purchasing power. The date the calculator returns is a projection under fixed assumptions rather than a schedule.
Reaching £500,000 from £150,000 with £20,000 annual savings takes approximately 9.3 years.

Sources & Methodology
Methodology
This calculator models year-by-year compound growth to determine when a net worth target is reached. Starting from your current net worth, it applies your expected annual return rate each year and adds your annual savings contribution. The computation continues iteratively until the projected net worth equals or exceeds your target figure. The model assumes a constant annual return rate, consistent annual savings amounts, and no withdrawals or changes to these inputs over time. It does not account for fees, taxes, inflation, market volatility, or variations in actual returns. Results represent a simplified projection based on these steady-state assumptions and should not be interpreted as a forecast of actual outcomes.
