Future pricing is the way to figure out the fair value of a futures contract, which is a deal to purchase or sell an underlying asset at a fixed price on a set date in the future. The current spot price of the asset is not the only thing that determines the price of a futures contract. Instead, it is figured out by adding the cost of storing or carrying the item until the end of the period.
This cost can include interest, storage, and other costs. Futures pricing commonly uses a cost-of-carry framework: carrying costs (e.g., financing, storage where applicable) are added, and known income/yield (e.g., expected dividends, convenience yield as applicable) is adjusted, consistent with no-arbitrage logic. The no-arbitrage concept is the main notion underpinning futures pricing. This means that there shouldn't be a way to make money without taking any risks between the spot and futures markets. Arbitrageurs are traders who make transactions to bring prices back to normal if there is a price discrepancy.
Futures pricing makes sure that everyone knows what the prices are, helps traders set price expectations, and makes all financial markets the same. It is very significant for hedging, speculating, and risk management, especially when it comes to equities, commodities, and currency futures.
How is the Price of a Futures Contract Determined?
The price of a futures contract is generally calculated using the cost-of-carry model, which establishes the fair value of a futures contract by considering both the current market price of the underlying asset and the cost or benefit of holding it until the expiry date. In simple terms, the futures price reflects what the asset should logically be worth on the settlement day if there are no risk-free profit opportunities in the market. The formula commonly used is:
Futures Price = Spot Price × (1 + Risk-Free Interest Rate × Time to Expiry) – Expected Income or Yield. A common representation is F = S × e^{(r + carrying costs − income/yield)T}; the exact form depends on the asset and assumptions (discrete/continuous compounding).
Here, the spot price refers to the current market price of the asset. The risk-free interest rate typically represents the return on government-backed securities for the same time period, and the time to expiry is measured in days, months, or years, depending on the contract. The expected income or yield may include dividends in the case of equity futures or benefits arising from holding certain commodities.
The result of this calculation is known as the theoretical price, which acts as a benchmark. However, the actual market price may differ due to factors such as market speculation, transaction costs, liquidity, demand-supply changes, and investor sentiment.
When a noticeable difference arises between the theoretical and market prices, traders may execute arbitrage strategies to benefit from the price gap, helping the market return to equilibrium. Therefore, while the formula provides a structured and logical valuation, real-world pricing also reflects behavioural and market-driven influences.
Things to Consider in Futures Pricing
When evaluating futures pricing, it is important to understand several influencing factors beyond the basic formula. The most common concept is the basis, which is the difference between the spot price and the futures price.
This difference can widen or narrow depending on interest rates, carrying costs, and time left until expiry. As the expiry date approaches, convergence normally occurs, meaning the futures price tends to move closer to the spot price. Traders should also consider market liquidity, volatility, and expected returns while analysing price behaviour, as these elements can cause short-term deviations from the theoretical value.
Things to Understand in Futures Pricing
Margin Requirement: When trading futures, you don’t have to pay the full price of the contract. You only pay a small amount, margin call, as a security deposit.
Mark-to-Market (MTM): Every day, your profit or loss is calculated based on how the price moves. If the price goes your way, you earn money. You lose money if it goes against you. This cycle continues until you close the trade or it expires.
Convergence Principle: As the expiry date comes closer, the futures price slowly moves closer to the actual market price of the asset. By the expiry date, both prices usually become almost the same.
Assumptions vs Reality: The formula for pricing assumes that markets are perfect, cheap to trade in, and without easy profit tricks. But real markets can change due to news, demand, supply, and investor mood.

Different Future Pricing Models
There are mainly two commonly discussed models for pricing futures contracts: the cost-of-carry model and the expectancy model.
The cost-of-Carry Model is the most widely used. It explains that the futures price should be equal to the current market (spot) price plus the cost of holding or carrying the asset until the contract expires. These carrying costs may include interest, storage, insurance, or other expenses. If the asset provides any benefit, such as dividends or yield, that value is subtracted. This model is based on the idea that no trader should be able to make a risk-free profit, so spot and futures prices must stay logically linked.
The Expectancy Model, however, is based on traders' beliefs about the asset's price at expiry. Here, the futures price reflects market expectations and sentiment rather than only cost calculations, making it more market-driven and speculative.
What is Arbitrage in Futures?
Buy the underlying asset in the spot market.
Simultaneously sell an equivalent futures contract.
Hold until expiry, incurring carry costs (like interest).
Arbitrage seeks to capture pricing discrepancies; actual outcomes depend on transaction costs, funding, execution, and settlement factors
Summary
Futures pricing is grounded in the cost-of-carry model: you calculate what it would cost to hold the asset (borrowing cost, storage, etc.) and subtract expected benefits like dividends. This is a fair theoretical price, but real-world futures often deviate from this because of transaction costs, trader expectations, and margin requirements. Arbitrage helps bring futures prices back in line, but it’s rarely frictionless. Understanding these forces equips you to trade futures more intelligently and spot potential mispricings.
