Call Ratio Spread Calculator (1×2)
Payoff zones of buying one call and selling two higher-strike calls — credit/debit, peak profit and the naked upside risk point.
Formula
Ratio spreads monetize a 'drift up but not through' view, often for zero cost — the catch is the uncovered short call above the upper breakeven, where losses are unlimited. Pros run them on indexes where gap risk is smaller, or convert to butterflies by buying a far wing.
The embedded naked call carries unlimited risk above the upper breakeven. Not financial advice — for informational and analytical use only. Verify all figures with a qualified professional before acting on them.
