You cannot calculate it, since it depends on some varying factors like the image content and some other JPEG parameters like optimization or progressive.
You can use a program, e.g. AZImage - see links -, that allows you to fine set the compression parameters to get an idea about the resulting size.

How to calculate Compression ratio for an image?
compression ratio=uncompressed image size/compressed size
How do you calculate compression ratio?
compression ratio = compressed size / uncompressed size the ratio should be between 1 and 0 (multiply with 100 to get the ratio in percent) a ratio greater than 1 means, the compressed size is actually greater than the uncompressed size a ratio just below 1 means bad compression the lower the ratio, the better the compression
What is the maximum pressure and temperature produced inside a four stroke petrol engine for a given compression ratio?
How do you calculate compression?
Compression ratio in engineering can be calculated by dividing the total volume of a system before compression by the total volume after compression. In computing, file compression ratios are calculated by comparing the original file size to the compressed file size.
What is a critical compression ratio?
The lowest compression ratio of a compression-ignition engine that allows a specific fuel to be ignited by compression ignition.
What is the compression ratio to a Toyosha 142ci motor?
23:1 compression ratio
What is the Otto cycle efficiency formula and how can it be used to calculate the efficiency of an engine?
The Otto cycle efficiency formula is given by: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio of the working fluid. This formula can be used to calculate the efficiency of an engine by plugging in the compression ratio and specific heat ratio values. The higher the efficiency value, the more effectively the engine converts fuel into useful work.
What is the highest compression ratio?
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.

What is the compression ratio of NASCAR engines?
The compression ratio for NASCAR engines is limited to 12.0:1.
What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
