Futures Contracts Calculator
Print
A Futures Contract is a standardized financial agreement to buy or sell a specific commodity, currency, or equity index at a predetermined price on a specified future date. Futures trading relies on leverage via initial performance margins and daily mark-to-market settlements.
Our free Futures Contracts Calculator computes contract position value, total tick profit/loss, return on initial margin (ROIM), and theoretical fair futures prices using the cost-of-carry model.
How to Calculate Futures Contract Profit & Theoretical Fair Value
Futures calculations encompass daily market price shifts (ticks) and theoretical arbitrage-free pricing.
Theoretical Fair Futures Price Formula (Cost-of-Carry Model):
F = S × ( 1 + r + c - y )^T
Continuous Compounding: F = S × e^( ( r + c - y ) × T )
Futures Contract Profit & Loss Formulas:
Long Futures P&L = ( Exit Price - Entry Price ) × Contract Multiplier × Number of Contracts
Short Futures P&L = ( Entry Price - Exit Price ) × Contract Multiplier × Number of Contracts
Sub-Formula Components:
- S (Spot Price): Current spot market cash price of the underlying asset.
- r (Risk-Free Rate): Annual financing interest rate cost.
- c (Storage Costs): Storage, insurance, and handling costs expressed as a percentage.
- y (Convenience Yield / Dividend Yield): Income yield or benefit derived from holding physical inventory.
- Contract Multiplier: Fixed dollar value per index point or commodity unit (e.g., E-mini S&P 500 = $50 per point).
Standardized Futures Contract Specifications
Major futures contracts operate with specific tick sizes and contract multipliers:
| Futures Contract | Contract Multiplier | Minimum Tick Size | Tick Value ($) |
|---|---|---|---|
| E-mini S&P 500 (ES) | $50 per index point | 0.25 points | $12.50 per tick |
| Micro E-mini S&P 500 (MES) | $5 per index point | 0.25 points | $1.25 per tick |
| Crude Oil Futures (CL) | 1,000 barrels ($1,000/$1.00) | $0.01 per barrel | $10.00 per tick |
| Gold Futures (GC) | 100 troy ounces ($100/$1.00) | $0.10 per ounce | $10.00 per tick |
Step-by-Step Calculation Example
A trader goes long 2 E-mini S&P 500 futures contracts with the following trade metrics:
- Entry Futures Price: 5,000.00
- Exit Futures Price: 5,025.00
- Contract Multiplier: $50 per point
- Initial Margin Required: $12,000 per contract ($24,000 total)
Step 1: Compute Point Gain
Point Gain = 5,025.00 - 5,000.00 = +25.00 index points
Step 2: Compute Total Dollar Profit
Dollar Profit = 25.00 points × $50/point × 2 contracts = $2,500.00
Step 3: Calculate Return on Margin (ROIM)
ROIM = ( $2,500.00 / $24,000.00 ) × 100 = 10.42%
Frequently Asked Questions (FAQ)
What is Contango vs Backwardation?
Contango occurs when futures prices trade higher than spot prices (F > S) due to carrying costs. Backwardation occurs when futures prices trade lower than spot prices (F < S), typically caused by high immediate demand or supply shortages.
What is the difference between Initial Margin and Maintenance Margin?
Initial Margin is the equity capital required to open a futures contract position. Maintenance Margin is the minimum equity balance required to keep the position open. If equity falls below maintenance margin, a margin call is triggered.
How does daily Mark-to-Market work in futures trading?
At the close of every trading day, futures positions are settled against daily settlement prices. Profits are credited to trader accounts in cash, and losses are debited immediately.
