Naked Call / Put Formula

A naked short option keeps premium when it expires worthless and loses as intrinsic value grows.

Worked Examples

Load these examples to compare common naked call / put payoff outcomes.

NAKED CALL

Stress-test an uncovered short call

A short call moves above its break-even and creates losses.

  • Enter the manual prices and assumptions.
  • Review the calculated risk, reward, and break-even metrics.
  • Compare the chart with the highlighted scenario.

Result: the calculator updates the scenario metrics and chart from those inputs.

Real fills, fees, and broker margin rules are not modeled.

How It Works

This calculator models uncovered short call or short put payoff at expiration.

Example Problem

Choose call or put, then enter strike, premium received, contracts, and expiration stock price.

  1. Calculate premium received.
  2. Subtract intrinsic value owed at expiration.
  3. Find break-even.
  4. Review maximum profit and maximum loss.

Uncovered options can involve substantial margin, assignment, and unlimited or very large losses.

Key Concepts

Short options collect limited premium but can lose far more than the credit received.

Applications

  • Understanding naked option risk.
  • Comparing short call and short put break-evens.
  • Stress-testing uncovered short-option outcomes.

Common Mistakes

  • Focusing on premium without max loss.
  • Ignoring margin calls.
  • Assuming assignment only happens at expiration.
