Use the responsive form below. It shows three columns on large screens, two on smaller screens, and one on mobile.
1. Notional Value
Notional Value = Current Price × Contract Size × Number of Contracts × FX Rate
2. Base Initial Margin
Base Initial Margin = Notional Value × Initial Margin Rate
3. Base Maintenance Margin
Base Maintenance Margin = Notional Value × Maintenance Margin Rate
4. Total Initial Requirement
Total Initial = Base Initial + Volatility Add-on + Concentration Add-on + Gap Risk Add-on − Hedge Credit
5. Total Maintenance Requirement
Total Maintenance = Base Maintenance + 80% × (Volatility + Concentration + Gap − Hedge Credit)
6. Variation Margin / Unrealized P&L
Variation Margin = Direction Multiplier × (Current Price − Entry Price) × Contract Size × Contracts × FX Rate
7. Account Equity
Account Equity = Available Capital + Variation Margin
8. Stress Loss
Stress Loss = Notional Value × Worst-case Adverse Move
9. Top-up Needed
Top-up to Initial = Max(0, Total Initial Requirement − Account Equity)
The model is designed for planning and screening. Real exchange, broker, spread, and intraday margin methodologies may use SPAN-style or proprietary rules.
| Scenario | Direction | Contracts | Current Price | Notional Value | Initial Margin | Maintenance Margin | Account Equity | Status |

| Index Hedge | Long | 2 | 4,950.00 | USD 49,500.00 | USD 5,445.00 | USD 4,158.00 | USD 6,500.00 | Healthy |
| Short Energy | Short | 3 | 4,300.00 | USD 129,000.00 | USD 15,738.00 | USD 12,332.40 | USD 13,000.00 | Watch |

These sample rows illustrate how capital, direction, and risk add-ons affect margin health.
Futures margin is collateral required to open and maintain a futures position. It is not a down payment on the contract value. It protects the clearing system against daily mark-to-market losses.
Initial margin is the higher amount needed to open the trade. Maintenance margin is the lower threshold you must keep afterward. Falling below maintenance can trigger a margin call or forced reduction.
Variation margin reflects daily profit or loss from price movement. When the market moves against you, equity drops. When it moves in your favor, equity rises and reduces pressure on the account.
Add-ons create a more conservative estimate. They help account for unstable markets, overnight gaps, and concentrated exposures that basic margin rates alone may underestimate.
Hedge credit represents margin relief from offsetting positions or recognized hedges. Some brokers or clearing firms reduce requirements when positions lower net portfolio risk.
No. This tool is for estimation and planning. Real requirements depend on exchange rules, broker overlays, intraday policies, spread treatment, and product-specific methodology.
Stressed equity shows account equity after a hypothetical adverse move. It helps you see whether the account could still support the position during a sharp market shock.
Use it as a rough sizing limit based on your current capital and estimated initial margin per contract. It is useful for screening, but it should not override liquidity, volatility, or broker limits.
