Business rule for contracts

[joshmorris]

On contracts I want the total cost to be worked out by payment amount x payment schedule x length of contract so say the payment amount is 100 pound and payment schedule is quarterly and length of contract is 2 years. I would want it to do 100 x 4 x 2 so total cost of the contract is 800 pound. Is this possible to configure as I'm new to this.

Yes, that is possible, but you need to get all variations in there (maybe go for a flow and use variables). You can do calculations within Javascript, so that's the easy part, you just need to put all of those variables within your script/flow.

So for any schedule, you need to define the correct value to calculate. If you have daily or weekly payments (I don't think you will, but you never know), you also need to check for leap years and/or years with 53 weeks instead of 52.

So where would I start to configure this as I have no experience in this area?
