Variation margin in futures: how daily settlement moves cash
Learn what futures variation margin means, how mark-to-market settlement affects account equity, and why it differs from initial and maintenance margin
Direct answer
Variation margin is the cash adjustment that reflects a futures position's mark-to-market profit or loss. It is different from initial margin, which supports opening a position, and maintenance margin, which sets a minimum equity level for keeping it open. Understanding the cash movement helps explain margin calls and apparent changes in buying power.
What variation margin records
Futures are revalued through the clearing process at a settlement price. A long position receives a positive cash adjustment when the settlement price rises relative to the prior settlement, while a short position receives the opposite adjustment. The contract's tick value and number of contracts determine the amount.
[Futures mark-to-market](/learn/futures-mark-to-market-explained) explains the settlement concept. The exact timing and accounting display depend on the exchange and broker; a platform may show an unrealized figure before the official settlement is posted.
A simple calculation
Suppose one contract has a $25 tick value and the settlement moves 12 ticks in your favor. The variation-margin credit is approximately $300 before fees (12 × $25). A move of 12 ticks against the position is approximately a $300 debit.
That cash adjustment changes account equity and available funds. It does not change the contract's notional value, and it does not turn initial margin into a loss limit. A later reversal can debit cash even if the position previously showed a profit.
How it relates to margin levels
Initial and maintenance margin are thresholds; variation margin is the realized settlement transfer. If repeated debits push equity below maintenance, the broker can request funds, reduce the position, or liquidate it. Initial vs. maintenance margin and margin call vs. forced liquidation explain those thresholds.
Intraday credits may not be withdrawable immediately, and overnight requirements can reserve more funds. Check available-to-trade, available-to-withdraw, and settled cash separately rather than treating one balance as universal.
Plan for reversals and gaps
Before entry, record tick value, contract count, settlement schedule, margin levels, current equity, and the broker's liquidation policy. Stress several consecutive adverse settlements and a gap beyond the planned stop. Keep a buffer for fees, other positions, and changing requirements.

Common questions
Is variation margin the same as initial margin?
No. Initial margin is collateral required to open; variation margin is the profit or loss cash adjustment from settlement.
Can a variation-margin debit trigger a margin call?
Yes. If settlement losses reduce equity below maintenance, the broker may request funds or take risk-reducing action.
Can I withdraw a variation-margin credit immediately?
Not always. Settlement timing, collateral rules, other positions, and broker policies can limit available-to-withdraw cash.
Does variation margin cap my futures loss?
No. It transfers losses as they are settled, while the leveraged position can continue to lose and a gap can exceed the deposited margin.
