The P-Fin 8 Index is a publicly available, eight-question measure of financial literacy developed by the TIAA Institute and the Global Financial Literacy Excellence Center (GFLEC). Introduced in 2026 as part of the 10th anniversary of the TIAA Institute-GFLEC Personal Finance Index (P-Fin Index), it offers a practical way to measure financial literacy using a short instrument.
The full P-Fin Index uses 28 questions to assess knowledge across eight areas of personal finance: earning, consuming, saving, investing, borrowing and managing debt, insuring, comprehending risk, and go-to information sources. The P-Fin 8 includes one question from each area, selected through empirical analysis to best proxy the full 28-question index.
