How it works
- Equivalent ending amount = × ÷ ; Inverse purchasing power = × ÷
- Worked example: 50 × 120 ÷ 100 = 60; 50 × 100 ÷ 120 ≈ 41.6666667
- Supported input limits: : 0 ≤ x ≤ 1,000,000,000,000; : 1e-12 ≤ x ≤ 1,000,000,000,000; : 1e-12 ≤ x ≤ 1,000,000,000,000; : n ≤ 100; : n ≤ 100; : n ≤ 100

Assumptions and limitations
Supply comparable index values from the same series and market, using a consistent base. No inflation data is fetched. The equivalent amount follows that index ratio and may not match a particular household’s spending or an exchange-rate change.
