If you're talking about the US, single payer healthcare would be nowhere close to a "rounding error". Medicare and Medicaid are already more than 5% of GDP.
Only 5% is not so bad at all honestly. Apollo program was like 5%. Especially when you consider the population eligible for medicare and medicaid is already paying the highest medical costs (the point of the system in the first place after all).
