How to use it
- Choose CPI history or a custom inflation scenario, then enter the amount, start year, end year, and salary-growth assumption if you are comparing income. Use the same period the real-life decision spans instead of a random historical window.
- Read cumulative inflation, annualized inflation, and purchasing-power loss together. At roughly 3% inflation, purchasing power is cut in half in about 24 years using the Rule of 72.
- If salary growth is below inflation, you took a real pay cut even if your paycheck rose. That matters for wage negotiations, retirement targets, and emergency-fund sizing.
- Use the result to restate expenses, salary, or goals in today's dollars, then check the personal effect with the real raise calculator or retirement calculator instead of leaving the answer as an abstract percentage.
- Re-run when CPI assumptions move, when you change the years being compared, or before updating long-term plans. Track real income growth and real expense growth, not just nominal changes.

Agent playbook
- Resolve Inflation Impact Calculator from /agent-tools.json and open its contract before execution.
- Validate inputs against the contract schema instead of scraping labels from the page UI.
- Open the browser page only when a person wants to review charts, assumptions, or related tools.
Agent FAQ
Should ChatGPT, Claude, or another agent click through the UI?
No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.
When do tools show Quick and Advanced?
Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.
When should an agent still open the browser page?
Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.
Questions people usually ask
What years are available in CPI mode?
The baked-in CPI range spans 2000 through 2025 with annual-average values.
Can I run future what-if inflation scenarios?
Yes. Custom mode lets you set your own annual inflation assumption.
How should I interpret salary delta?
A negative salary delta means projected salary growth lags inflation-adjusted purchasing needs.
Is this country-specific?
CPI mode uses US data. For other regions, use custom mode with local inflation assumptions.
Is this professional advice?
No. Outputs are planning estimates only — not financial, tax, or investment advice.
