Calculation Methodology & Official Data Sources (2026)
Unlike automated calculators that extrapolate macroeconomic CPI/GDP indices often disconnected from tourist reality, TravelComparator.org combines on-the-ground price audits across 23 cities, central bank exchange rates, and official customs regulations.
1. Our 4 Pillars of Data Collection & Verification
Every price and rule displayed in our interactive tools is cross-checked against at least three independent sources:
On-the-Ground Price Audits & Weighted Numbeo Index
We track real local-currency prices for accommodation (hostels, 3★ hotels/riads, 4-5★ resorts), dining (street food, 3-course restaurant dinners, cafe coffee, bottled water), and urban transit (metered taxis, public buses/metro).
Official Exchange Rates & Closed-Currency Regulations
EUR and USD conversions use official reference rates (ECB) while accounting for real-world banking rules: closed currencies (TND, MAD, DZD), ATM withdrawal caps, and mandatory local ATM operator surcharges (e.g., 220 THB in Thailand).
Customs Allowances, Drone Laws & Airport Regulations
Our customs guides verify exact duty-free quotas for tobacco and alcohol, cash currency declaration thresholds, and strict import bans (drones, binoculars, vaping devices).
Telecom Audit, Local Operators & International eSIMs
We compare prepaid tourist SIM plans from national carriers (Ooredoo, Maroc Telecom, Djezzy, AIS, Vodafone, Cosmote, Turkcell) against international eSIM providers to help travelers eliminate roaming fees.
2. Why Algorithmic CPI Calculators Overestimate North Africa & Asia Costs
Many generic travel cost websites rely on automated Consumer Price Index (CPI) formulas or international business hotel rates. This creates massive distortions that our field-verified methodology corrects:
| Destination | Generic Algorithmic Estimate | Verified Real Budget (3★ Standard) | Field Explanation (Why the gap?) |
|---|---|---|---|
| 🇹🇳 Tunisia (Tunis, Sousse, Djerba) | ~€125 / day ($137) | €45 to €58 / day | Generic algorithms overweight USD-priced international business hotels, whereas local 3-4★ hotels, metered taxis (€0.30 flag drop), and restaurants cost 60% less in Tunisian Dinars (TND). |
| 🇩🇿 Algeria (Algiers, Oran, Constantine) | ~€110 / day ($120) | €36 to €45 / day | Public subsidies on fuel and transit (metro/tram ticket ~€0.30, full meal €2.50–€10) keep daily on-the-ground expenses remarkably low. |
| 🇲🇦 Morocco (Marrakech, Fes, Agadir) | ~€105 / day ($115) | €45 to €60 / day | Abundant traditional riads (€45–€60/night for two) and authentic Moroccan dining cut automated estimates in half. |
| 🇪🇬 Egypt (Cairo, Luxor, Hurghada) | ~€95 / day ($105) | €38 to €50 / day | Egyptian Pound (EGP) devaluation gives Euro and Dollar travelers exceptional purchasing power on dining, Uber/Careem rides, and hotels. |
| 🇹🇭 Thailand (Bangkok, Chiang Mai, Phuket) | ~€90 / day ($98) | €38 to €55 / day | Street food (€1.50–€2.50), BTS/MRT transit, and competitive Thai hospitality deliver 3-4★ comfort for under €50/day excluding flights. |
