What is Purchasing Power?
Purchasing power is the real value of money — what it can actually buy. When inflation is 3% per year, a basket of goods that costs $100 today costs $103 next year. Your dollar buys 3% less. Over 25 years at 3%, that $100 buys only about $48 worth of goods in today's terms.
The Rule of 72 for Inflation
Just like growth, you can estimate how long until inflation halves your purchasing power: divide 72 by the inflation rate. At 3% inflation, purchasing power halves in about 24 years. At 7% (like 2022), it halves in just ~10 years. This is why holding cash long-term is a guaranteed slow loss.
Why Your Investment Return Must Beat Inflation
A 5% nominal return at 3% inflation is only a 2% real return. That's what you actually gain in purchasing power. If your savings account earns 2% but inflation is 4%, you're losing ground in real terms even though your balance is growing. Always compare returns to inflation, not to zero.
Inflation and Retirement Planning
A $5,000/month retirement budget today will feel like less and less over time. After 20 years at 3% inflation, it has the purchasing power of only ~$2,770 in today's dollars. Retirees must either have inflation-adjusted income (Social Security, TIPS) or a portfolio large enough that withdrawals keep up with rising costs.
