Break-even age is when you hit a specific financial milestone. Could be FIRE (financial independence), debt-free, or a specific net worth target. This calculator takes current age and financial position, then projects the age you hit your target.
Age 35 with 100,000 net worth, saving 20,000/year at 7% return, targeting 1,000,000: reach target at age 55. Same setup targeting 2,000,000: age 63. Increase savings to 30,000/year: age 58 for 2M target.
The tool is motivating - converting abstract 'saving for retirement' into 'you'll hit FI at age 55'. Run multiple targets to see curves. Often small increases in savings (another 200/month) compress the timeline meaningfully. The difference between saving 15% and 25% of income typically shifts break-even by 8-12 years.
Run it with sensible defaults
Using current age of 35, current net worth of 100,000, target net worth of 1,000,000, annual savings of 20,000, the calculation works out to Age 53. 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 Age, Current Net Worth, Target Net Worth, Annual Savings, and Investment Return — do not pull with equal force. 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.
How the math works
Year-by-year compounding of current net worth plus annual savings until target reached. Break-even age = current age + years to target. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Using this to recalibrate
Repeat the calculation with smaller inputs to see how much the final figure moves. That sensitivity is where the actionable insight lives — often a modest change today produces a dramatically different lifetime total.
What this doesn't capture
This is an illustration, not a prediction. The specific figure depends entirely on your inputs — change any assumption and the headline moves. The value is in the pattern it reveals, not the exact pound figure.
From age 35 years with £100,000 £ + £20,000 £/yr at 7% to £1,000,000 £ = Age 53.
