Retirement Readiness Score
A retirement readiness score is a summary metric — typically expressed as a percentage or on a numerical scale — that measures how well-prepared an individual or household is to fund their projected retirement income needs based on current savings, expected future contributions, projected investment growth, anticipated Social Security benefits, and retirement spending targets.
Retirement readiness scores were developed by financial institutions, plan record-keepers, and financial planning software providers to translate the complexity of retirement projections into an accessible single number that motivates action. While the specific methodology varies by provider — Fidelity, Vanguard, T. Rowe Price, and Morningstar each use proprietary models — most share a common logical structure.
The numerator of a readiness score is the projected annual income the household can sustainably generate in retirement from all sources: portfolio withdrawals at a safe withdrawal rate, Social Security benefits at the projected claiming age, any defined benefit pension income, and other recurring income sources such as rental income or part-time work. The denominator is the projected annual spending target in retirement, typically expressed in today's dollars and adjusted for inflation to the expected retirement date. A score above 100% indicates that projected income exceeds projected needs; a score below 100% indicates a shortfall.
Fidelity's well-known retirement savings benchmarks — saving 1x salary by age 30, 3x by 40, 6x by 50, 8x by 60, and 10x by retirement — are simplified versions of a readiness calculation that assumes an 85% income replacement target and a 30-year retirement horizon. These benchmarks allow quick self-assessment without requiring a full financial plan.
Retirement readiness scores are sensitive to their input assumptions. Small changes in assumed portfolio returns, retirement age, Social Security claiming strategy, or spending inflation can produce large swings in the score. A household scoring 85% readiness on a 6% nominal return assumption might score only 72% if returns are modeled at 4% — a plausible difference given current market valuations. Understanding the assumptions embedded in any readiness score is essential to interpreting it correctly.
The primary value of a retirement readiness score is not its precision but its directional guidance: households scoring below 70-75% have a meaningful gap that requires intervention — higher savings, lower spending targets, later retirement, or some combination. Households scoring above 90% have significant flexibility. Regular re-scoring (annually or after major financial changes) allows households to monitor whether they are on track and to course-correct before gaps become difficult to close.
