1. What is Purchasing Power Parity (PPP)?

Purchasing Power Parity (PPP) is an economic theory that compares different countries' currencies through a "basket of goods" approach. In commercial deals, PPP helps assess whether a deal price represents good value compared to a standard reference price.

2. How Does the Calculator Work?

The calculator uses the PPP formula:

Where:

• \( Deal\ Price \) — The price being evaluated (same currency as standard price)
• \( Standard\ Price \) — The reference price for comparison

Interpretation:

• PPP = 1: Deal price equals standard price (parity)
• PPP < 1: Deal price is better than standard (discount)
• PPP > 1: Deal price is worse than standard (premium)

3. Importance of PPP Calculation

Details: PPP calculations help businesses evaluate pricing strategies, compare deals across markets, and assess value for money in procurement and contracting.

4. Using the Calculator

Tips: Enter both prices in the same currency. The standard price should reflect your benchmark or market reference price for the product/service.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between PPP and simple price comparison?
A: PPP provides a standardized ratio that can be compared across different products, services, and markets, while simple price comparison only shows absolute differences.

Q2: How should I determine the standard price?
A: The standard price should be based on market averages, historical prices, or competitor pricing for equivalent products/services.

Q3: Can PPP be used for services as well as goods?
A: Yes, PPP can be calculated for any deal where you have both a deal price and a meaningful standard reference price.

Q4: What PPP value indicates a good deal?
A: Generally, values below 1.0 indicate better-than-standard pricing, but the acceptable threshold depends on your specific requirements and market conditions.

Q5: How often should PPP be recalculated?
A: PPP should be recalculated whenever standard prices change significantly or when evaluating new deals.
