  5. Where the scorecard appears

The wellness scorecard grades nine ratios from your plan’s projection against two thresholds each. A ratio at or past the better threshold grades Strong, one between the two grades Fair, and one short of both grades Needs attention. Every figure reads a value the projection already reports; the scorecard never changes the projection.

A metric whose inputs the plan doesn’t have is left off the scorecard.

  • Essential spending counts essential and uncategorized expenses, the essential part of an expense with a discretionary percent, loan payments, property costs and health coverage. Discretionary expenses, gifts and taxes don’t count.
  • Retirement is your first milestone whose name mentions retirement and not a partner, the same milestone the Success odds tab uses. The retirement metrics read the first full calendar year after it, against balances at that year’s start. If the milestone is already in the past, they read the first plan year against opening balances, and Financial independence is left off.
  • A partial first year is scaled to a full year wherever a year’s flow is set against a balance or an annual target: monthly essential spending, earned income for savings to income and a first-year withdrawal rate. Ratios of two flows in the same year need no scaling.
  • Liquid follows each account’s liquid setting: a withdrawal-locked account, or one you exclude, isn’t liquid and isn’t counted in savings to income or the withdrawal rate.

The target multiple of income is 1× at 30, 3× at 40, 6× at 50, 8× at 60 and 10× at 67, straight-line between those ages and from 0× at 25. It stays at 10× after 67. At 25 and younger the metric is left off.

Savings to income=Opening account balances÷Earned income for a full year

A 46-year-old starts a plan in January 2026 with a $100,000 salary, $40,000 of essential and $10,000 of discretionary expenses, a $20,000 car loan at $500 a month, $30,000 in checking, $200,000 in a traditional 401(k) and $100,000 in a brokerage account.

Debt payments are $6,000 ÷ $100,000 = 6% of income, which is Strong.
