Cash Allocation Explained: Are You Holding Too Much or Too Little Cash?
The One-Sentence Definition
Cash allocation is a 0-100 score for how close your wallet cash is to 20% of your total net worth. Hit 20% exactly and you score 100. Every percentage point off knocks 2 off the score.

The Intuition: Why 20%?
20% is a balanced default - enough to cover emergencies and short-term opportunities without sacrificing too much long-term growth. It is not law. Conservative savers might prefer 30%. Aggressive young investors might prefer 10%. The point is to have a target and know how close you are to it.
Person A: 5% cash
Almost everything invested. Great for compounding - but no cushion. A surprise expense or a market drawdown forces selling at the worst time. Score around 70 (15 points away from target × 2).Person B: 50% cash
Half in cash, half invested. Very safe - but most of the money is earning below inflation. Score around 40 (30 points away from target × 2).The score is symmetric: holding too little cash gets penalised the same as holding too much. Both extremes are problematic, just for different reasons.
What the Mixed Badge Means
Inside Turbobulls, every metric carries a small scope badge that tells you what data feeds it. Cash allocation carries the Mixed badge.
That means it blends two scopes in its calculation:
- Wallet cash (your tracked cash accounts) - the numerator.
- Total net worth (wallet + portfolio + broker cash - debt) - the denominator.
The ratio of one to the other is what the score is measuring.
How to Read the Number
| Score | What it typically means |
|---|---|
| 90 - 100 | Right at your cash target (within 5 percentage points). Comfortable buffer, not bloated. |
| 70 - 90 | Close to target. Minor rebalancing might help, but not urgent. |
| 40 - 70 | Meaningful deviation. You're either holding too little or too much cash. Worth investigating. |
| 0 - 40 | Far from target. Either critically under-cash (one bad month away from forced selling) or significantly over-cash (large amounts losing real value to inflation). |

The Cost of Getting It Wrong
Too little cash: You're forced to sell investments at the worst time. A 10% market drawdown plus an emergency expense can compound into a 30%+ realized loss because you had to sell to raise cash. The "buying high, selling low" trap.
Too much cash: Inflation quietly erodes your purchasing power. At 3% inflation, 50,000 sitting in cash loses about 1,500 of real value every year - even though the nominal number doesn't change. Over a decade, that's tens of thousands of lost real wealth.
How Turbobulls Calculates Cash Allocation
In plain words: Turbobulls computes what percentage of your net worth is sitting in your wallet as cash. Then it measures how far that percentage is from 20%, and converts the gap into a 0-100 score.
cashPercent = walletBalance / totalNetWorth × 100
distance from target = the gap between cashPercent and 20% (always positive, whether over or under)
score = 100 − distance × 2 (floored at 0)
Compute the cash percentage. Wallet balance divided by total net worth, in percentage terms.
Find the distance from target. Absolute difference between your cash percentage and 20%.
Convert to a score. Subtract distance × 2 from 100. Floor at 0.
When Cash Allocation Matters - and When to Ignore It
- Rebalancing portfolios. Use the score as a trigger to top up or trim cash.
- After big market moves. A market rally can leave you under-cash; a drawdown can leave you over-cash.
- Before recurring large expenses. Make sure you have enough cash to cover them without selling.
- Long-term planning. A consistently bad score signals systemic over- or under-investing.
- You have a different deliberate target. If you've decided on 30% or 10%, the 20% score won't match your strategy.
- You hold significant non-cash safe assets. Bonds and money market funds count as portfolio, not cash, in this metric.
- Your net worth is tiny. The percentages swing wildly when net worth is small.
- You just made a big transfer. The score will spike then settle - wait for it to stabilise.
