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

Try 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. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Current Net Worth, Target Net Worth, Annual Savings, and Expected Return. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

The formula behind this

Year-by-year compound growth of current net worth plus annual savings. Stop when target reached. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

The annual review habit

Plug new numbers in every year. Income changes, expenses shift, markets move. A plan that isn't revisited quietly drifts out of date. This tool is cheap to re-run — so re-run it.

What this doesn't capture

Real plans get re-run against new information every year or two. The result here is a reasonable direction, not a destination. Treat it as a starting point for thinking, not a commitment to a specific future.

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. Worth a few minutes each, honestly.

Example Scenario

Net worth milestone produces a year count based on the inputs provided.

Frequently Asked Questions

Why not a simple formula?
Compound growth plus contributions doesn't have a clean closed form for time. Iterative simulation gives exact answer.
Good milestones to target?
100k (first big compounding base), 250k (decade marker), 500k (halfway to millionaire), 1m (millionaire). Each one motivates different behaviour.
What if I'm already past?
Tool shows zero years. Set a bigger target or check the one you picked.
How to hit milestones faster?
Raise savings rate primarily. Returns matter more at higher balances. Cutting spending compounds — every pound saved also isn't spent tomorrow.
