The Real Impact: Fixed Income vs Rising Costs

This calculator demonstrates what happens when your income stays flat while living costs rise. For someone with little or no spare income, this isn't just reduced savings — it's a direct hit to lifestyle and quality of life.

Year-by-Year Erosion of Purchasing Power

This table shows how costs compound over time while income remains fixed. The "Weekly Shortfall" column represents the gap between what you earn and what you'd need to maintain the same lifestyle.

Visualising the Gap: Income vs Cost of Living

💡 Why This Matters

For those with spare income: This erosion means reduced capacity to save, invest, or build wealth. Your surplus shrinks each year.

For those living on the edge: This isn't just numbers — it represents real choices: skipping medications, eating less, turning off heating, or missing social activities.

The compounding effect: Unlike a one-off cost, inflation compounds. A 3% annual increase doesn't just add 3% — it multiplies on top of previous increases, accelerating the gap over time.

Pensioners are protected... partially: Government pensions are indexed to the higher of CPI or PBLCI, but self-funded retirees with fixed drawdowns or those on other fixed incomes don't receive this protection.
