# Tracking Funding Rate Impact on Your Crypto P&L

Funding rates are one of the most overlooked costs in crypto futures trading. A trade that looks profitable at face value can be a loss after funding fees — and your journal should make this visible.

## What Is a Funding Rate?

On perpetual swaps, the funding rate mechanism keeps the perpetual price close to the spot price. Every 8 hours (on most exchanges), longs pay shorts (or vice versa) based on the rate:

- **Positive funding:** Longs pay shorts. This happens when the market is bullish/leveraged long.
- **Negative funding:** Shorts pay longs. This happens when the market is heavily short/bearish.

Typical rates: 0.01%–0.03% every 8 hours. During extreme markets: 0.1%–0.3% per 8 hours.

## How to Calculate Funding Cost on a Trade

```
Funding cost = Position size × Funding rate × Number of funding periods held
```

Example: $10,000 long on BTCUSDT at 0.05% funding, held 24 hours (3 funding periods):
- Cost = $10,000 × 0.05% × 3 = $15

On a trade targeting $50 profit, $15 in funding is 30% of your target eaten by fees.

## What to Record in Your Journal

For every crypto futures trade, add:

- **Funding rate at entry:** Check the exchange and note it
- **Hold duration:** Hours from entry to exit
- **Funding periods:** How many 8-hour periods passed
- **Estimated funding cost:** Calculate and record
- **Net P&L:** Gross P&L minus funding minus trading fees

## Tagging Funding Conditions

- `funding-high-long`: Opened long when funding > 0.05% — you paid above-average funding
- `funding-neg-long`: Opened long when funding was negative — you received funding income
- `funding-neutral`: Funding was 0.01%–0.02% (normal range)

## What the Data Reveals

After tracking 50 trades with funding data:
- What is your average funding cost as % of P&L?
- Do you tend to open longs during high positive funding (crowded trades)?
- Are your overnight holds disproportionately costly?

Many active traders discover that 10–20% of gross profits disappear to funding + fees — a number that changes risk management decisions significantly.

## Summary

Funding rates are invisible until you track them. Adding three fields to your journal (funding rate, hold duration, funding cost) turns an invisible cost into a visible performance factor you can optimize.
