Most investors check their portfolio and see one number: total value. Maybe they subtract what they put in to get a rough profit figure. That's a starting point — but it answers only the most basic question. It tells you nothing about how efficiently your capital is working, how much risk you're taking to get those returns, or whether you're beating the simplest alternative of just buying an index fund.
These five metrics answer the questions that actually matter. They're not just for institutional investors — any serious individual investor should be tracking all of them.
1. Internal Rate of Return (IRR)
IRR is the most important single metric for any portfolio. Unlike simple return percentages, IRR accounts for when you invested each euro — making it the only metric that gives you a true apples-to-apples comparison across different investments and time periods.
A 40% return sounds great. But whether it's impressive or not depends entirely on how long it took. IRR annualizes the return so you always know what your money was earning per year, regardless of holding period or cash flow timing.
What to look for: Compare your portfolio IRR against your benchmark (usually a broad market index). If your IRR is consistently below the S&P 500 equivalent, you're underperforming the simplest passive strategy. Read our full IRR guide for a deeper explanation.
Track it: Monthly at the portfolio level; quarterly per individual asset.
2. Total Return vs. Invested Capital
This metric is simpler than IRR but complementary — it tells you the absolute growth of your wealth in euros (or your base currency), not just a percentage.
Where Total Invested Capital is the sum of all contributions you've ever made across all assets, net of withdrawals.
Why track this alongside IRR? Because they answer different questions. IRR tells you the rate at which your money grew. Total return tells you how much actual wealth was created. A high IRR on a small investment creates less absolute wealth than a moderate IRR on a large one.
What to look for: Steady growth in total return over time. A flat or declining total return despite positive IRR suggests you've been withdrawing more than you're earning.
Track it: Monthly. This is your "headline number" — the clearest measure of whether you're building wealth.
3. Asset Allocation vs. Target Allocation
Your target allocation is the strategic split you chose between asset classes — for example, 60% stocks, 20% real estate, 10% crypto, 10% cash. Your actual allocation is what you currently hold.
Over time, these drift apart as some assets outperform others. A 10% crypto allocation that doubles becomes 20% of your portfolio, taking on more concentration risk than you intended. Tracking the gap between target and actual allocation tells you when it's time to rebalance.
| Asset class | Target allocation | Current allocation | Drift | Action needed? |
|---|---|---|---|---|
| Stocks / Funds | 60% | 55% | −5% | Monitor |
| Real estate | 20% | 21% | +1% | No action |
| Crypto | 10% | 18% | +8% | Rebalance |
| Cash | 10% | 6% | −4% | Monitor |
What to look for: Any asset class drifting more than 5–10 percentage points from its target is a signal to consider rebalancing.
Track it: Monthly as a quick sanity check. A good portfolio dashboard shows this automatically as a pie chart or percentage breakdown.
4. Income Yield
Not all returns come from asset appreciation. Dividends from stocks, rent from real estate, staking rewards from crypto, and interest from bonds or deposits all generate income that contributes to your total return — and that income matters independently.
Tracking income yield separately from capital gains helps you understand the income-generating capacity of your portfolio — which is especially important if you're building toward financial independence or planning to live off your investments.
A portfolio with a 4% income yield generates €4,000 per year for every €100,000 invested, regardless of what markets do. That income is real cash flow you can spend or reinvest, and it provides a cushion during market downturns when asset values fall.
What to look for: For income-oriented investors, a yield of 3–5% is a common target. Growth-oriented investors may accept lower yield in exchange for higher capital appreciation potential.
Track it: Monthly. Log every dividend, rental payment, and staking reward as it arrives to keep the calculation accurate.
5. Maximum Drawdown
Maximum drawdown measures the largest peak-to-trough decline your portfolio has experienced. It's the most direct measure of how much pain you would have had to endure at the worst moment — and it's a crucial reality check on risk.
For example, if your portfolio peaked at €150,000 and then fell to €105,000 before recovering, your maximum drawdown was −30%. That's the real-world risk you experienced, not a statistical abstraction.
Why it matters: Many investors accept high volatility in theory but panic-sell in practice. Knowing your historical maximum drawdown helps you understand whether your actual risk tolerance matches your theoretical one — and whether your current allocation is sustainable for you emotionally and financially.
💡 Rule of thumb: If your maximum drawdown would have forced you to sell, your allocation is too aggressive. A good allocation is one you can hold through its worst historical period without changing the plan.
What to look for: Compare your maximum drawdown to that of the S&P 500 (which has experienced drawdowns of 30–50% in major crises). If your portfolio drawdown is much larger, your allocation carries more risk than the broad market.
Track it: Review quarterly. Track it as your portfolio grows so you have a complete picture of the range of outcomes you've actually experienced.
Putting it all together
These five metrics form a complete performance picture when read together:
- IRR tells you how efficiently your capital is working
- Total return vs. invested capital tells you how much wealth you've actually built
- Allocation drift tells you whether you're staying on strategy
- Income yield tells you how much passive income your portfolio generates
- Maximum drawdown tells you what the real-world risk feels like
None of these requires a finance degree to understand. They do require clean, consistent data — which means logging every transaction, keeping your portfolio up to date, and using a tool that calculates these metrics automatically rather than forcing you to do it in a spreadsheet.
