What is the Surplus rung?
Surplus is whatever sits above the ladder once the three rungs below are covered. It has no target and no colour, and what it is for is your decision rather than arithmetic.
Surplus is the fourth rung: what sits beyond independence, and what you choose to do with it. It has no target and is not meant to have one — it is simply whatever is left above the ladder once Survival, Sustenance and Sufficiency are covered. The card says so directly: what it is for is your decision, not an arithmetic one.
The four rungs
| Rung | Protects against | Held as |
|---|---|---|
| Survival | A shock that will not wait | Cash you can reach the same day |
| Sustenance | Income stopping | A laddered runway, no growth assets |
| Sufficiency | The number itself | One equity-to-debt decision |
| Surplus | What comes after | Whatever you choose it to be |
Each rung has its own purpose, its own target formula and its own instrument mix. They are not four versions of one allocation model.
The four rungs side by side. Surplus is the last row: what comes after, held as whatever you choose it to be.
Illustrative figures — not anybody’s real plan.
How it shows on the page
- The bar always draws all four rungs. Surplus gets a fixed, hatched band after the end of the ladder, because an open-ended amount cannot be drawn to scale.
- Its readout row says No target — this is what is left over, and its card carries no funding word or meter.
- Before anything is there, the card reads Nothing above the ladder yet. This rung fills itself once the three below it are covered.
Surplus while Sufficiency is still short
Money is placed on Surplus only once the three rungs below are filled. While Sufficiency does not yet read Funded, the Surplus card adds a note — Sufficiency is not covered yet, so this is money that could still be doing the work of the rung below it. It is a note, never a lock: Surplus is shown at whatever level it exists.
Money you have ticked as your Emergency fund never lands on Surplus, however much of it there is. It stays on Survival, because a shock buffer is the opposite of spare money.
When you are past the top
Once what you hold covers the FI number, the line at the top of the page reads Your corpus covers what the plan says independence costs. What you add from here is Surplus. Well past it, with money still going in each month, it says the page is now about what that surplus is for.
