What A Funded Ratio Measures

A funded ratio compares what a household has against what it has committed to spend. The measure comes from pension accounting, and applying it to an individual plan changes what the plan reveals.

The numerator and denominator both need valuing

Assets are relatively straightforward: portfolio balances, the value of guaranteed income streams, and any other resources intended to fund retirement.

Future spending is harder. It must be projected across the full horizon and then discounted back to a present value, which requires a discount rate.

The result is a ratio. Above one, resources exceed commitments on current assumptions; below one, they do not.

The discount rate does most of the work

A higher discount rate makes future spending look cheaper today and pushes the ratio up. A lower one does the reverse, and the sensitivity is considerable over long horizons.

Using an expected portfolio return as the discount rate embeds an assumption that risky assets will deliver, which is precisely the thing the measure is supposed to test.

Using a low, near-certain rate produces a more conservative figure that answers a different question: whether the plan works without relying on risk being rewarded.

The ratio changes what a market fall means

A portfolio fall lowers the numerator, but if interest rates rose at the same time the discount rate rises too, lowering the denominator.

The funded position can therefore be more stable than the portfolio balance alone suggests, because both sides respond to the same conditions.

Watching only the asset side can trigger reactions to a change that has not actually worsened the household's position relative to its commitments.

Surplus and shortfall imply different actions

A plan with a comfortable surplus has options: it can reduce investment risk, increase spending, or bring forward gifts, and the surplus makes those choices visible.

A shortfall points to a limited set of levers — spending, working longer, or accepting more risk — and quantifies how much each would need to move.

Framing the position this way tends to produce more specific conversations than a portfolio balance considered on its own.

What the measure cannot capture

The ratio is a snapshot under one set of assumptions. It says nothing about the range of paths that could lead away from that snapshot.

It also depends on a spending projection that is itself uncertain, particularly for late-life care costs whose distribution is extremely wide.

Used alongside path-based analysis rather than instead of it, the ratio contributes a clear present-tense reading that projections tend to obscure.
