About this calculator
The Theoretical Forward Price Calculator computes the forward price of an asset using the spot price (S), risk-free interest rate (r), and time to maturity (T). The formula S·e^(rT) models the continuous compounding cost of carrying the asset, assuming no dividends or storage costs. This approach is standard in financial pricing models to ensure arbitrage-free valuations.
This tool is commonly used in finance for forward contracts, such as options or delivery agreements. For instance, when trading a contract to buy a stock in the future, the theoretical price ensures alignment with market equilibrium. The calculation assumes continuous compounding rates, a common simplification in theoretical frameworks.
Note that the formula does not account for real-world factors like dividends, taxes, or transaction costs. It also assumes a frictionless and efficient market. For dividend-paying assets, adjustments incorporating the continuous dividend yield are necessary for accurate results.
Frequently asked questions
What is the difference between theoretical and market price?
Theoretical price is a mathematical model result, while market price reflects actual supply and demand. Discrepancies may signal arbitrage opportunities.
Why use continuous compounding instead of annual compounding?
Continuous compounding is a mathematical simplification that better models financial markets' 24/7 activity, like stock exchanges.
Can I use this calculator for dividend-paying assets?
Not directly. For dividend-paying assets, adjust the formula using S·e^(-dT), where 'd' is the dividend yield.
What risks are involved in relying on theoretical prices?
Theoretical prices assume ideal conditions. Real-world factors like unexpected volatility or liquidity costs may deviate from model predictions.
