What is PPP purchasing power parity definition
PPP is a way to compare buying power across countries by adjusting for typical price levels instead of just swapping currencies. It is often used in purchasing power parity salary checks to see how far income might stretch.
- What it measures: relative price levels between places.
- Where it comes from: broad price baskets tracked over time.
- Why it is used: to see buying power differences beyond FX, including PPP ratio meaning for quick comparisons.

PPP vs FX: how they differ
| Term | What it does | What it does not do |
|---|---|---|
| FX conversion | Swaps currency at a market rate to show nominal amounts. | Does not reflect local prices or buying power. |
| PPP adjustment | Adjusts for average price levels to show relative buying power. | Not a bank rate, not city specific, not a forecast. |

What PPP is not
- Not a spendable exchange rate.
- Not city level pricing.
- Not a promise of lifestyle.
- Not personal budgeting advice.
Two quick illustrative examples
Example 1: Same net pay, different prices. $60,000 net in Country A vs Country B with a PPP ratio of 0.7. FX shows $60,000 either way, but PPP suggests the buying power feels like $85,000 in Country B. Illustrative only.
Example 2: FX looks great but PPP shows less change. €50,000 in Country C converted to $55,000 by FX, but PPP ratio of 1.1 means local prices are higher, so the PPP adjusted salary feels closer to $50,000. Illustrative only.

FAQs
Is PPP the same as FX?
No. FX converts currency; PPP compares price levels to show buying power.
Can I spend PPP rates?
No. PPP is a comparison metric, not a spendable rate.
Does PPP reflect my city?
PPP is national. City costs can differ, so pair it with local checks.
Why does PPP sometimes show a big lifestyle gain?
If the destination basket is cheaper, PPP may show higher buying power even when FX looks flat.
Does PPP include rent?
Housing is part of the basket on average, but your rent may differ.
Is PPP a forecast?
No. It is descriptive and does not predict future prices.
How does PPP relate to after tax salary?
Estimate net pay first, then use PPP to see buying power. See the after tax explainer for steps.
Is this advice?
No. This is educational and not financial, tax, legal, or relocation advice.
Does PPP include taxes?
PPP itself does not model tax. Use a tax estimate first, then apply PPP.
