IFR Module 214 -- Decade-by-Decade Data Visualization
No one can predict the future economic environment. This data shows the dramatic variability of key economic factors over the past century. The IFR approach embraces this unpredictability by building plans that are needs-based rather than rate-of-return-based.

Key Insights for Financial Planning
Unpredictability is the Norm
Every decade looks radically different. Stock returns ranged from -0.1% (1930s) to 19.4% (1950s). Any plan built on a single assumed rate of return is built on sand.
Needs-Based Planning Works
The IFR approach focuses on NEEDS (protection, income, legacy) rather than PREDICTIONS (what rate will I earn?). This makes plans robust regardless of economic conditions.
Tax Rates Have Been Much Higher
The top marginal rate was 91% in the 1950s. Today's rates of 37% are historically low. Planning as if current rates will last forever is a dangerous assumption.
Inflation is the Silent Thief
Even "low" inflation of 3% cuts purchasing power in half every 24 years. The 1970s saw 7.4% average inflation -- destroying fixed-income purchasing power in a single decade.
Interactive: What If You Retired in Each Decade?
This chart uses actual year-by-year S&P 500 total returns to show how a $1,000,000 portfolio would have performed over 30 years with $50,000 annual withdrawals, depending on when you retired.
The Sequence of Returns Risk: Even with the same average return, the ORDER of returns matters enormously. A 2000 retiree faced three consecutive down years (dot-com bust) followed by the 2008 crash — nearly depleting their portfolio. Meanwhile, a 1970 retiree survived the '73-'74 bear market and then rode the 1980s-1990s bull run to over $20M. Same withdrawal rate, radically different outcomes. This is why protection-based income guarantees are a critical component of retirement planning.
