How to Track Your ETF Portfolio for Free (S&P 500, QQQ, VOO)
How to track S&P 500 ETFs like SPY, QQQ, and VOO alongside crypto and other assets for a complete net-worth view.
ETFs like SPY (S&P 500), QQQ (Nasdaq 100), and VOO (Vanguard S&P 500) form the core of most index investing strategies. If you hold these alongside crypto or gold, tracking them in a single dashboard gives you a much clearer picture of your total financial position than checking each brokerage account separately.
Why ETF Tracking Matters Beyond Your Brokerage
Your brokerage app shows your ETF holdings — but only within that brokerage. Problems arise when:
- You hold ETFs and crypto separately — no single view of both.
- Multiple brokerage accounts — e.g., a 401(k) with Fidelity and a taxable account with Schwab.
- No allocation breakdown — you don't easily see what percentage of your wealth is in equities vs crypto vs cash.
A separate portfolio tracker that accepts manual entries solves this without requiring you to connect your accounts.
Adding ETFs to WalletLens
WalletLens supports US ETFs including SPY, QQQ, VOO, VTI, and many others. To set up ETF tracking:
1. Open walletlens.live/dashboard.
2. Tap Add asset and search for the ticker (SPY, QQQ, VOO, etc.).
3. Enter your share count and your average purchase price (cost basis).
4. Your ETF appears in the dashboard with the live price, P&L, and allocation percentage.
Repeat for each ETF you hold across different accounts. The dashboard blends them all into a single net-worth view.
Seeing ETFs Alongside Crypto and Gold
The real value of WalletLens for ETF investors is the mixed-asset view. If your financial picture includes:
- VOO shares from a brokerage account
- Bitcoin from a Coinbase wallet
- Gold coins stored at home
...no single app from any of those providers shows the complete picture. WalletLens does, because it uses manual entry rather than account linking.
Common ETF Portfolios to Track
3-Fund Portfolio:
- US Total Market (VTI or FSKAX)
- International (VXUS or SWISX)
- Bonds (BND or FXNAX)
Simplified 2-Fund:
- VOO (S&P 500)
- BND (Total Bond Market)
Tech-Heavy:
- QQQ (Nasdaq 100)
- SOXX (Semiconductors)
Add any of these by ticker in WalletLens to see your ETF portfolio alongside your other holdings.
How WalletLens Calculates ETF P&L
The calculation is straightforward:
- Current value = Shares × Live price
- Cost basis = Shares × Your average purchase price
- P&L = Current value − Cost basis
This is the same method your brokerage uses. WalletLens just shows it alongside all your other assets in one place at walletlens.live — free, no account needed.
