Though in reality it's less with discounts, for example I pay around £2.90 per month for PS Plus, and upgraded to Game Pass Ultimate using the promotion exploit, making it just £3 a month for both Game Pass and Xbox Live Gold.
That said, I think I'm done with subscriptions and can't imagine paying for or adding any more, unless Sony did something similar to Game Pass, but even then, only if their exclusives were there day one. This is on top of Internet, mobile bills etc, which also add up to maybe an additional £50 a month on top.
