Thank You for your quick reply Milbo
Now i want to clear you more
The matter For example some one enters the age 18 the price increased by 1% Like the product price is $50 and the customer enter the age 18 the product price become $50.5 and if some one enters the age 25 the price decreased by 5% Like the price is $50 and the customer enter age 25 the price become $47.5 There is not means they are only two ages he will enter The user will enter his age. The price according to some age formula which can be changed at any time as per market price.
Now pls let me know the plugin suggested to me will work according to these requirements or we have to do in coding.

I am sorry that we have still no demo.

The plugin is done for dimensions, so you need to adjust it a bit. If you buy it, I show you where, you can do it with beginner php skills. I can do it also for a fee.
