See I love quick and dirty rules to get close enough through estimation for whatever I'm mental mathing, because if I need exact numbers I'm turning to a computation device
20% of 36.23 I'd be going "okay 20% of 10 is 2, 3 10s in 36 so 3x2=6, and 6.23 is pretty close to half 10 and half 2 (from my previous 20% of 10 calculation) is 1 so 20% of 36.23 is slightly more than 7"
36.23% of 20 I'd be going "30% of 10 is 3, 2 10s in 20 so 2x3=6, 6.23% is close to 5 so half of 3 is 1.5, 6+1.5=7.5 so 36.23% of 20 is a bit more than 7.5"
Now which is closer to correct? Ehh I'm not sure I haven't used a calculator yet, but I'm mental mathing so chances are my estimation got me close enough that I can just round to whichever direction is safer for errors and call it good. Usually I'm mental mathing to figure out splitting a bill, a tip or to double check some machine computed math that looks wrong, and none of those call for perfect precision, just getting close enough that it doesn't matter
The biggest thing insurance does is limits risk. When you have insurance and get a big hospital bill, you generally have more bargaining power with the hospital than if you don't have insurance. When enrollment time comes run the numbers and look at the costs. You can also apply and review options on the health insurance marketplace which usually involves applying for Medicaid in the process. For kids under 18 Medicaid has a family income cap of like $8k/month so if you have kids they're definitely covered by Medicaid
Personally, I'm not sure what I'm going to do in 2026 if the subsidy isn't renewed. I'm an independent contractor so my health insurance options are entirely limited to the marketplace, and while I currently have a plan that costs $1250/month with the $1100/month subsidy I only pay $150/month for insurance which is quite reasonable. Every plan I saw on the marketplace cost a minimum of $900 or more per month.
I simply do not make enough (and I'm not allowed to work more hours than I currently am so that's not an option) to be able to afford insurance if the above math is the same for 2026. My plan right now is, keep job hunting and maybe my wife starts job hunting too since my contract work can work around the kids' school schedules (and my youngest starts going to school full time next year rather than half time) so we don't need a non-working parent as long as this contracting lasts for, and we probably won't get coverage through the marketplace in 2026 unless I can get it for about $400/month or less, because at that point I'm probably better off risking dumping more money into my emergency fund and hoping we don't have any medical emergencies (and planning on negotiating with the hospital if we do) I don't like the risk level of no insurance but we may simply be priced out of having insurance if the healthcare marketplace subsidy isn't renewed
