Leverage Calculator

How the calculation works

Leverage here is notional (or position) value divided by the capital posted as margin or equity for that position. A result of 5 means each $1 of margin controls $5 of position. Margin as a percent of position is the reciprocal view (margin ÷ position × 100).

Formula & example

Leverage = position value ÷ margin used

$50,000 position on $10,000 margin → 5× leverage.

Why use this calculator

Leverage amplifies P&L symmetrically in percentage-of-margin terms. Knowing the multiple clarifies how fast equity can move and how close you may be to margin calls or liquidation rules set by the broker or venue.

When to use it

Use before entering margin, futures, CFDs, or leveraged crypto notionals — anytime position value exceeds cash committed.

Background

Buying securities with borrowed funds (margin) has existed for centuries in various forms; modern U.S. equity margin was formalized under Federal Reserve Regulation T after the 1929 crash, which still shapes how brokerages express initial and maintenance margin today.

Tips for accurate results

• Broker margin requirements can change.
• Pair with liquidation awareness on crypto/futures.
