School term time salary calculator

Is there a website to help calculate term time salary, similar to the salary calculator- but obviously for term time 🙏
It's not a simple divide by 52 weeks and multiply by 46 (or however many weeks) as it relates to part year (so can't be based on a full year's holiday entitlement).
Just looking for some help as I can't work something out and wondered if there was such a thing..... I have googgled but can't see anything obvious.

Close but not really.  It's only for Beginning of June to End of Aug I need to work out payment for. 
The current .actual. annual salary I have is for a Sept to August year which is fine.  However as June to August doesn't have the full years holiday allowance, it's been worked down to several thousand less annual salary, but I can't seem to be able to check it anywhere.
