Metodologi dan Sumber Data
Bagaimana Spend.lookval bekerja, dari mana data berasal, dan asumsi apa yang kami buat.
1. Data kekayaan miliarder
Primary source: Forbes Real-Time Billionaires list.
Net worth figures are estimates based on publicly available financial data — stock holdings, private company valuations, real estate, art collections, and other assets tracked by Forbes. Key points:
- Figures are in US dollars (USD) and may not reflect pre-market or after-hours price movements.
- Private company valuations (e.g. SpaceX, OpenAI) are estimated and can vary significantly between reporting periods.
- Net worth does not include illiquid assets such as trusts, hidden holdings, or debt obligations beyond what is publicly known.
- All data is for educational and entertainment purposes — it is not financial advice.
2. Estimasi harga barang
The simulator features 100+ items across 12 categories (yachts, jets, cars, watches, homes, tech, food, experiences, donations, sports, business, islands). Prices are estimated as follows:
| Category | Pricing Method | Examples |
|---|---|---|
| Yachts | Based on manufacturer MSRP and brokerage listings for comparable models. | Azimut 80 ($4.5M), REV Ocean ($650M) |
| Private Jets | Based on manufacturer list prices and industry valuation guides (VREF, Aircraft Bluebook). | Gulfstream G700 ($79M), Boeing 747-8 VIP ($400M) |
| Supercars | Based on manufacturer MSRP and collector market data. | Porsche 911 Turbo S ($230K), Bugatti Chiron ($4M) |
| Watches | Based on retail prices from official brand boutiques and gray market data. | Rolex Daytona ($35K), Graff Diamonds ($55M) |
| Homes | Based on recent real estate listings and public sale records for comparable properties. | Beverly Hills Mansion ($15M), The One Bel Air ($500M) |
| Technology | Based on manufacturer pricing and market rates. Bitcoin price from major exchange averages. | Apple Vision Pro ($3.5K), Nvidia DGX H100 ($400K) |
| Food | Based on standard menu prices and restaurant pricing for luxury experiences. | Dinner at Noma ($500), Year with Private Chef ($2M) |
| Experiences | Based on published prices from providers and industry estimates. | Blue Origin Space Trip ($1M), SpaceX Orbital Flight ($50M) |
| Donations | Illustrative amounts representing typical charitable giving levels. | Local Food Bank ($1K), Global Health Foundation ($100M) |
| Sports | Based on recent franchise valuations (Forbes Sports Money) and industry estimates. | MLS Club ($500M), NBA Franchise ($3B) |
| Business | Based on typical startup/company valuations at different growth stages. | Food Truck ($50K), Social Platform ($2B) |
| Islands | Based on private island listings and real estate comparables. | Private Island Caribbean ($25M), Island Resort ($200M) |
3. Konversi mata uang
The tool supports 10 currencies: USD, PLN, EUR, BRL, INR, IDR, TRY, JPY, KRW, VND.
Base prices are in USD. Conversion to other currencies uses:
- Primary: Exchange rates fetched from our backend API, updated from financial data providers.
- Fallback: Hardcoded baseline rates stored in the client bundle for offline/fallback scenarios.
- Caching: Rates are cached in localStorage for up to 24 hours to reduce API calls.
Currency conversion is a visual approximation — actual exchange rates fluctuate in real time and may differ from the rates used in the tool.
4. Perhitungan simulasi pengeluaran
The simulator uses a straightforward calculation:
Wealth Spent (%) = Total Cart Value / Billionaire Net Worth × 100Where:
- Total Cart Value = Sum of (item price × quantity) for all items in the cart.
- Net Worth = Billionaire's total net worth in USD (from Forbes data).
The progress bar updates in real time as items are added or removed. Once the cart exceeds 100% of net worth, the display shows "Fortune spent!" but continues tracking.
5. Metodologi kalkulator waktu
Results are mathematical estimates that do not account for interest, inflation, taxes, investment returns, or changes in spending habits over time.
6. Perhitungan skenario
- Spend $1K/day: Net worth ÷ ($1,000 × 365.25) = years to spend it all.
- Buy Jets/Islands: Net worth ÷ item price = maximum number that can be purchased.
- Pool Fortunes: Sum of all 15 billionaires' net worth = combined total.
- 24-Hour Spree: Net worth ÷ 86,400 seconds = spend rate per second.
- Give to Everyone: Net worth ÷ 8,000,000,000 = amount each person receives.
Results are simplified mathematical illustrations. Real-world constraints (market liquidity, time constraints, logistics) are not considered.
7. Fitur perbandingan
- Difference: The absolute difference in net worth between two billionaires (A − B).
- Years to Earn: How long it would take at $60,000/year (average US salary) to earn each fortune. This is a simple division and does not account for taxes, savings rates, or career progression.
- Jet/Island Equivalents: How many Gulfstream G700 jets ($75M each) or private islands ($25M each) each billionaire could buy with their entire fortune.
8. Biografi dan fakta menarik
