Use this Monte Carlo simulation calculator tool to estimate probabilities and forecast outcomes based on random sampling.
Monte Carlo Simulation Calculator
This Monte Carlo Simulation Calculator allows you to define a range of values, a threshold, and the number of simulations to estimate the probability that a randomly selected value within the defined range will meet or exceed the threshold.
How To Use
- Number of Simulations: Enter the number of simulations to run. The more simulations, the more accurate the result.
- Low Range Value: Enter the lower bound of the range from which random values will be sampled.
- High Range Value: Enter the upper bound of the range from which random values will be sampled.
- Threshold Value: Enter the value that the randomly generated numbers are compared against to determine success.
- Click the Calculate button to perform the simulation.
- The Result field will display the estimated probability that a randomly generated number within the defined range will meet or exceed the threshold.
How It Works
The Monte Carlo method uses repeated random sampling to obtain numerical results. In this calculator:
- We define a range [lowRange, highRange] and a threshold value.
- We run a number of simulations (numSimulations).
- For each simulation, a random value is generated within the range.
- If the random value meets or exceeds the threshold, it is counted as a success.
- The result is the ratio of successful trials to the total number of trials, indicating the probability.
Limitations
While Monte Carlo simulations can provide good approximations, they are not exact and depend on the number of simulations run; higher numbers yield more accurate results but take longer to compute. Additionally, this implementation assumes uniform distribution within the range and does not account for other distributions or real-world complexities.
Use Cases for This Calculator
