Azure Web App: Why is premium cheaper than standard

Question

Below is a suggestions on scaling up my Azure Web App, Azure gives me.

I don't really understand, why Premium is cheaper than Standard, if it has more ACU, as well as the premium benefits. The machines are currently nearly idle, but I dont think this makes a differnece in that calculation.

210 total ACU
3.5 GB memory
Dv2-Series compute equivalent
70.80 EUR/Month (Estimated)

S3
400 total ACU

A-Series compute equivalent
233.93 EUR/Month (Estimated)

P2V2
420 total ACU
7 GB memory

Answer 1

Under normal circumstances, the price of scale up my Azure Web App can be calculated.

On calculator（P2V3）.

On portal(P2V3).

On calculator（S3）.

The price calculated through the Azure Calculator should not appear as you said, but the actual price is related to the subscription, so the benefits you enjoy will be different.

My subscription is not pay as you go type, so there will be different degrees of discount. Under normal circumstances, prices are calculated through the azure calculator. The actual payment is based on the price you see on the portal (may be related to subscription, enjoy different discounts).
