========================================================
Understanding basis calculation is essential for traders in futures, options, and crypto derivatives. Basis reflects the difference between the spot price of an asset and its futures price. Accurately calculating and interpreting basis helps traders identify arbitrage opportunities, manage risks, and optimize hedging strategies. In this basis calculation tutorial, we’ll explore multiple methods of calculating basis, explain their implications, and provide practical insights for both beginners and professionals.
Introduction to Basis
What Is Basis?
Basis is defined as:
Basis = Futures Price – Spot Price
It reflects the relationship between the futures market and the underlying spot market.
- A positive basis (futures > spot) often indicates contango, where futures are priced higher due to carrying costs such as interest or storage.
- A negative basis (futures < spot) indicates backwardation, usually driven by high demand for immediate delivery or scarcity of the asset.
Why Basis Matters
Basis is more than a number—it impacts arbitrage, hedging, and speculative decisions. Professional traders consistently track it because even small changes can open or close profit opportunities. This is why understanding how to calculate basis in perpetual futures is a fundamental skill for modern traders.
Methods of Basis Calculation
1. Absolute Basis Calculation
The simplest approach is to subtract the spot price from the futures price.
Formula:
Basis = Futures Price – Spot Price
Example:
- Futures price: $20,100
- Spot price: $20,000
- Basis = $100
This positive basis suggests contango, meaning futures are priced above spot.
Advantages:
- Easy to calculate.
- Quickly shows market structure.
Disadvantages:
- Lacks context regarding percentage deviation.
- Less useful when comparing across assets of different price ranges.
2. Relative Basis Calculation (Percentage)
To normalize across different assets and price ranges, traders use percentage-based basis.
Formula:
Relative Basis (%) = (Futures Price – Spot Price) / Spot Price × 100
Example:
- Futures price: $2,020
- Spot price: $2,000
- Relative Basis = (20 / 2000) × 100 = 1%
This provides a more standardized view of whether the futures are trading at a premium or discount relative to spot.
Advantages:
- Enables comparison across multiple assets.
- Better for analyzing arbitrage profitability.
Disadvantages:
- Slightly more complex than absolute calculation.

Hedging
Traders use basis to optimize hedging. For example, a farmer selling wheat futures should watch basis changes closely to avoid over- or under-hedging.
Arbitrage
Basis forms the foundation of cash-and-carry arbitrage strategies. When futures trade significantly above spot, traders buy the spot asset and short the futures to lock in profit. This is why many institutional traders study how to use basis for arbitrage in perpetual futures to exploit risk-free spreads.
Market Sentiment
Basis is a reflection of supply-demand dynamics and trader expectations. Persistent contango often signals bullish market expectations, while backwardation indicates strong spot demand.
Basis in Perpetual Futures
Why Perpetual Futures Are Unique
Unlike standard futures contracts, perpetual futures have no expiry. Instead, they rely on a funding rate mechanism to keep the contract price close to the spot price.
How Basis Functions in Perpetual Markets
In perpetual futures, basis is often expressed through the funding rate. If perpetual futures trade above spot, long traders pay short traders a funding fee, and vice versa.
Monitoring these differences is critical because why basis matters in perpetual futures trading lies in its ability to signal profitable funding arbitrage or hedging opportunities.
Basis in perpetual futures is tied to funding rate mechanics, unlike standard futures contracts
Comparing Basis Calculation Methods
| Method | Formula | Best Use | Pros | Cons |
|---|---|---|---|---|
| Absolute Basis | Futures – Spot | Quick market check | Easy to compute | Not standardized |
| Relative Basis (%) | (Futures – Spot) / Spot × 100 | Arbitrage & comparisons | Standardized, scalable | Requires more steps |
| Funding Basis (Perpetuals) | Derived from funding rate | Crypto derivatives | Adjusted for perpetual features | More complex |
Recommendation: For traditional markets, start with absolute and relative basis. For crypto and perpetual futures, integrate funding rate analysis for a more complete picture.
Modern Tools for Basis Analysis
- Basis Analysis Platforms – Many trading terminals offer built-in basis trackers.
- Custom Spreadsheets – Traders often calculate relative basis using Excel or Python.
- Crypto Analytics Tools – Platforms like Glassnode and Coinglass provide basis and funding rate data.
By combining traditional calculations with analytics tools, traders gain an edge in understanding where to find basis data for perpetual futures and how to act on it effectively.
Industry Trends in Basis Usage
- AI-Powered Basis Forecasting – Machine learning models predict basis changes using volatility, liquidity, and sentiment data.
- Cross-Exchange Arbitrage – Traders increasingly exploit differences in basis across multiple exchanges.
- Institutional Adoption – Hedge funds and family offices use basis as a key indicator for crypto market structure.

Market outlook reports often track basis trends as indicators of forward-looking sentiment
Best Practices for Basis Calculation
- ✅ Always compare both absolute and relative basis for a complete view.
- ✅ Adjust calculations for transaction costs when evaluating arbitrage.
- ✅ Use real-time data—basis opportunities disappear within seconds.
- ✅ Track historical basis patterns to anticipate changes.
- ✅ For perpetual futures, integrate funding rates into analysis.
FAQ: Basis Calculation Tutorial
1. How does basis affect perpetual futures?
In perpetual futures, basis is closely tied to funding rates. A positive basis means futures trade above spot, leading to funding payments from longs to shorts. A negative basis means the opposite. Understanding this helps traders align strategies with expected funding costs.
2. How to hedge using basis in perpetual futures?
Hedging with basis involves holding opposite positions in spot and futures. For example, a trader holding Bitcoin can short perpetual futures when the basis is positive, effectively locking in returns while neutralizing exposure to price fluctuations.
3. Where to access basis analytics for perpetual futures?
Professional traders rely on data providers like Coinglass, Skew, or TradingView. Many also build Python scripts that fetch real-time data from exchanges via API. This enables basis tracking across multiple platforms simultaneously.
Conclusion
This basis calculation tutorial demonstrates that basis is more than a formula—it’s a critical market signal for arbitrage, hedging, and trading strategy. By mastering absolute, relative, and perpetual basis calculations, traders gain the ability to interpret market sentiment and act on profitable opportunities.
Whether you are a retail investor exploring simple futures or an institutional trader building complex hedging models, basis analysis is indispensable.
