I would also join the advisers. If there are few subdomains, then it might make sense to buy a separate SSL certificate for each of them. Sometimes it is cheaper than buying a WildCard SSL certificate.
There is a second point, whether a certificate is suitable for you 1. only with domain verification or 2. it would be nice for a visitor to see confirmation of the name of your organization in the SSL certificate information (the latter require more thorough verification and are more expensive).
Conducted a mini-price analysis, this is the situation at the moment:
a) ISPsystem - from 18,707 rubles / year
b) firstSSL - from 14,300 rubles / year
e) sslcertificate.ru - from 15,000 rubles / year
There is also such a site GoGetSSL with very attractive prices, but it is not suitable for everyone. The company is registered in Latvia, and therefore payment from a legal entity is not available.

such a certificate is called WildCard which is immediately on *.site.ru
We needed it with documents, so we bought it from WebNamez.ru. Calculate for
yourself what is more profitable for you, 3 inexpensive certificates for site.ru, shop.site.ru, money.site.ru or one but on *.site.ru

You install the certificate
apt-get install python3-certbot-apache
If for nginx
apt install python3-certbot-nginx
Register it and connect the example to nginx.
certbot --nginx -d domain.com -d www.domain.com
Subdomains

certbot --nginx -d poddomen.domain.com -d www.poddomen.domain.com

More details Here Site on SSL Apache, Nginx Ubuntu
And on hosting with an ISP panel, you also get a Let's Encrypt certificate for free.

The prices and resources given in the answers are hardly relevant anymore. Good deals on wildcard certificates . If there are not many subdomains (up to 4-5), it is more profitable to purchase a multidomain certificate.
