Answer
Bottom line
Position A (employee)
Position B (employee)
Position B (employee) ends with 0.32x the median net worth of Position A (employee) (80,250 vs 249,798 GBP), retires about 7 years earlier (age 56 vs 63), and is more likely to reach its target within 40 years (84% vs 63%).
Target 430,000 GBP per position (rule: explicit); medians over 10000 paths, seed 42.

Net worth over time
Final net worth distribution
How it feels
Reference (outcomes below it count as losses) — Position A (employee): your target net worth (430,000 GBP); Position B (employee): your target net worth (430,000 GBP).
How this works
Losses sting about twice as much as gains feel good, and rare risks feel bigger than they are. This chart scales both positions' income together and re-reads the distributions the way a typical human would (cumulative prospect theory, Tversky & Kahneman 1992) — a decision aid, not financial advice.
Retirement and risk
| Metric | Position A (employee) | Position B (employee) | vs Position A (employee) |
|---|---|---|---|
| Goal | |||
| Target net worth | 430,000 GBP | 430,000 GBP | 1.00x |
| Target rule | explicit | explicit | |
| Phase rule | preserve | preserve | |
| Timing | |||
| Years to target, P10 | 18.0 | 13.0 | |
| Years to target, median | 28.0 | 21.0 | |
| Years to target, P90 | 45.0 | 38.0 | |
| Retire age, median | 63.0 | 56.0 | |
| P(retire within the horizon) | 63% | 84% | |
| Median wealth at retirement | 472,695 GBP | 472,073 GBP | 1.00x |
| Risk among retired paths | |||
| P(spending unfunded: ruin) | 23% | 60% | |
| Median year of ruin | 41.0 (age 76.0) | 33.0 (age 68.0) | |
| P(real net worth below zero) | 23% | 60% | |
| Median year below zero | 41.0 (age 76.0) | 33.0 (age 68.0) | |
| P(back below the target) | 77% | 95% | |
| Median year back below target | 31.0 (age 66.0) | 23.0 (age 58.0) | |
| P(target restored at the plan age) | 46% | 18% | |
A position stops working once its real net worth reaches its target; the ruin and restoration rows read the retired paths only.

How to read this report
Amounts are absolute in the display currency; the right-hand column shows the second position as a multiple of the first and reads n/a when either amount is zero or negative.
The target is typed; a path stops working once its real net worth reaches its target and then lives off the wealth — the country's net pension income where its payout rules ship, then the liquid wealth, then company withdrawals. The phase rule (preserve, checked at age 90) allows dips into principal on the way and reports them.
Ruin means the spending is not fully funded; below zero means the real net worth turns negative; back below the target counts a dip into principal after the target had been reached. The retirement, ruin and restoration rows read the retired paths only, and P(retire within the horizon) is the share retiring inside the report's horizon.
