Margin Call Price Calculator

A margin call fires when equity falls below the broker's maintenance requirement. The calculator finds the exact price that lights the fuse. The computation rests on Trigger price = loan ÷ (shares × (1 − maintenance margin)). Borrowing 10,000 against 400 shares with a 30% maintenance requirement triggers at 10,000 ÷ (400 × 0.7) ≈ 35.71 — about 29% below a 50 entry. Each input you type is substituted the instant you release the key, and the result is expressed in exactly the units or currency you chose.
