We can probably get the best rough idea of what Sanders himself would like the legislation to look like, by looking at what he has said, and the legislation he has already sponsored, but even this is likely only a general approximation of what the final sausage will look like.
I'd expect the M4A legislation to take the general form of the 2017 Senate bill he sponsored entitled
Medicare for All
The 2017 senate bill he sponsored appears to be substantially different than what he is proposing this time (at least from my non-legal expertise).
Section 303 of the bill seems to allow people to continue to use private insurance if they so choose.
Yet earlier this year, Sanders seemed to indicate that such private insurance would be banned.

Highlights:
(current cost of private Health Care in US = approx. $3.5T/year)
Costs of the Sanders M4A bill have been estimated at between $1.38T and a bit more than $2.5T/year.
Earier on you have suggested that the details of Sanders Medicare plan have not been finalized, yet now you're claiming that we can actually figure out how much it would cost. There seems to be some contradiction there.
And here's something you might want to think about... where exactly would those cost savings come from?
Yes, the U.S. health care system is extremely expensive. There are several reasons for that (so you can't assume going to "single payer" will fix all those problems, or if they do fix the problems, won't cause other problems.)
- Medical experts in the U.S. (e.g. doctors) often earn higher salaries than in other countries. How are you going to fix that? Make all medical people 'government employees'? Limit the amount they can charge? Either of those options may have the side effect of reducing available staff, causing an increase in waiting times
- Over-capacity, which means that some infrastructure is not fully utilized. It drives up costs, but it also means faster response time. Get rid of the extra infrastructure and wait lists may appear
- Medical lawsuits (which drives up insurance costs), and those have the secondary impact of forcing the doctors to order multiple tests (in order to avoid those lawsuits). Are you going to do anything to limit malpractice claims? What if a doctor actually does make a mistake?
- Administration overhead... Ok, this is possibly one area where single payer might make a difference. (Although not as much of a difference as you might think, since even in an all public system you need staff to handle the paperwork for claims.)
Unless you get in there and tackle those issues, you may find that health care costs don't really drop all that much, and if you DO try to address some of those issues, you may find that things like health care responsiveness suffer as a result.
And here's one more question you should ask yourself:
Lets say he gets elected in 2020. Sanders wants a "single payer/government covers everything/no private insurance" system. Lets say he manages to get it past congress, gets it implemented, and keeps it from getting overturned in the courts... You've reached nirvana, with your "free" health care covering everyone.
Eventually the Republicans will end up back in power (either winning the presidency or congress, or both).
Do you really want the republicans (the party filled with anti-abortionists, anti-science creationists/global warming deniers, and tea partiers) to have that much control over your health? The minute they gain power, they may decide to cut funding specifically for abortion. Or they may decide that the government has more important things to spend the money on, and needs to cut health care funding in order to spend more on the military. Without the private options that Sanders seems keen to ban, you'll be stuck.
And before you scoff at that, that same thing happened here in Canada (the place you seem to think is some sort of health care paradise). Back in 90s, the LIBERAL Prime Minister cut health care funding (partly to tackle the deficit, but largely to fund various pork-barrel projects). And that was a left-of-center party cutting spending. Who knows what the republican party would do in the same situation.
