Calculate disk space requirement for increasing replicas

Elastic Stack Elasticsearch
1

Im planning to increase replication of some of our indices and trying to understand the additional disk required for this. Looking at the test index below(1p:2r, store.size = 45mb, pri.store.size=15mb) would it be accurate to conclude that I would need 15mb more in the cluster if I increase replication by 1 and 30mb more if I increase it by 2 ?

health status index                                              uuid                   pri rep docs.count docs.deleted store.size pri.store.size
green  open   test_index_XXXXXXXXX                   AvRInVVWSnOWvfIQGNxD-g   1   2      55937            3         45             15
2

I would allow more just in case, but yes that's an accurate summary.
