Frequently Asked Questions
How is options profit calculated?expand_more
At expiry, a call is worth max(price − strike, 0) per share and a put is worth max(strike − price, 0). If you bought the option, your profit per share is that intrinsic value minus the premium you paid; if you sold it, it is the premium received minus the intrinsic value. The total is multiplied by the number of contracts and the lot size (100 shares per contract by default).
What is the breakeven price?expand_more
For a call, breakeven is the strike plus the premium; for a put, it is the strike minus the premium. Above (call) or below (put) that price, a long option starts making money. The breakeven is the same number whether you are long or short — it is just profit on one side and loss on the other.
Why does a short call show unlimited loss?expand_more
When you sell (write) a naked call, there is no ceiling on how high the underlying can rise, so your potential loss is theoretically unlimited. A short put's loss is capped only because the underlying cannot fall below zero. This is why selling options requires margin and careful risk management.
Does this include commissions and taxes?expand_more
No. The calculator shows the gross payoff at expiry before brokerage commissions, exchange fees, and any taxes. Singapore does not have capital gains tax, but trading costs still reduce your net result. It also assumes you hold to expiry rather than closing early.
