How to get an estimate of next year’s premiums

Hello all! 39f, rural VA

I currently have a high deductible insurance policy (Anthem Healthkeepers Bronze) that I purchased through healthcare.gov. I get an approx $60/month subsidy based on my income; my monthly premiums are around $350. I am currently pregnant and due in March of 2023.

Currently, my employer does not offer any sort of health insurance coverage, but they’re looking at changing that for 2023. I understand that should my employer offer coverage, I lose any tax subsidy if I elect to purchase my plan on the ACA. My employer understands this, and if the premium cost for my child and I ends up being more through the employer plan that I might pay on the exchange, they are willing to scrap the idea of offering employer based coverage in 2023 (I would be the only employee signing up; everyone else is on a spouse/parent’s policy.)

So my question is: how can I get an estimate of cost for a 2023 policy covering myself and my child on the exchange? I want to compare the potential costs.
