Salary Erosion
If your salary stays flat while inflation runs at 3%, you effectively take a 3% pay cut each year. Over a decade, you'd lose nearly 26% of your purchasing power.
Calculate how inflation and cost of living changes affect your money. Enter an amount and the inflation rate to see the adjusted value — whether you're planning a salary negotiation, budgeting for the future, or comparing prices across time periods.
See how inflation erodes your purchasing power and what adjustments are needed.
A cost of living increase (COLA) is an adjustment to wages, benefits, or budgets to keep pace with inflation. As prices rise, the same dollar amount buys less. COLA adjustments ensure your purchasing power doesn't erode over time.
If inflation is 3.5% annually, something that costs $100 today will cost $103.50 next year. Over 5 years at 3.5% annual inflation, you'd need $119 to buy the same goods. A $60,000 salary would need to become $71,253 just to maintain the same standard of living.
Without cost of living adjustments, your real income effectively decreases every year. Understanding this helps you negotiate fair raises, plan retirement income, and budget for future expenses accurately.

Rent, property taxes, insurance, and maintenance all rise with inflation. A $1,500/month apartment could cost $2,100+ in 10 years at 3.5% annual inflation.
Inflation is a retirement killer. What costs $50,000/year today could cost $90,000+ in 20 years. Your retirement savings must outpace inflation to maintain your lifestyle.
Rent/mortgage, insurance, property taxes, utilities, and maintenance. Housing is typically the largest component of the CPI basket.
Vehicle costs, gas prices, public transit fares, auto insurance, and maintenance. Fuel price spikes can dramatically affect this category.
Insurance premiums, deductibles, prescriptions, and medical services. Healthcare costs have historically risen faster than overall inflation.
Groceries and dining out. Food prices are sensitive to supply chain disruptions, weather events, and agricultural policy changes.
Tuition, books, childcare, and student loans. College tuition has outpaced general inflation for decades, rising 5-8% per year.
Clothing, entertainment, communications, personal care, and miscellaneous services round out the rest of the CPI basket.

$1,500/mo rent at 4% annual increase.
$40K/yr retirement budget in 20 years at 3.5% inflation.
$200/mo groceries at 6% food inflation for 3 years.
A COLA is a periodic increase to wages, benefits, or payment amounts designed to match inflation. Social Security, for example, applies an annual COLA to keep benefits aligned with rising costs.
The U.S. inflation rate fluctuates. Check the Bureau of Labor Statistics (BLS) CPI data for the most current rate. Historical average has been around 3% annually. Recent years have seen elevated inflation around 3-4%.
Ideally, yes. A raise that matches inflation maintains your purchasing power, but doesn't actually increase your standard of living. Only the portion of your raise above inflation represents a real increase in purchasing power.
Inflation compounds just like interest. 3% inflation doesn't mean prices rise 30% in 10 years — they rise about 34.4% because each year's increase is applied to the already-inflated price from the previous year.
Purchasing power is how much your money can actually buy. If prices double, your purchasing power is halved — the same $100 buys only half as much. The calculator shows what your current money will be worth in future "today's dollars."
