I can make the argument that you are just doing the math wrong but either way it sounds like high 90s rate.
Good job!
Yeah, should be added to numerator and denominator. If next month you make 300,000 more in commissions than you normally do will it be 300+ times higher?
But either way this is high! Did you pre-purchase some things in the previous month or is this an ongoing trend?
I know I'm doing the math wrong because the numerator is a basic numerical value for that one month (IE "Savings") and the denominator is an updated monthly average based on annualized income (IE, 11 months at 1k a month and 1 month at 10k would be 21k a year or 1.75k a month average - which doesn't work for that one 10k month, but helps me see our pace for the whole year)). A true saving rate would be "Month Savings" over "Month Income" (which still nets 96.9% savings rate: IE $6,886 saved over $7,100 earned) but still that's high.
It seems we bought monthly groceries right at the end of September, I pre-pay my water/utilities online in 600$ batches to avoid the $6.50 online fee for payment which means nothing was paid towards utilities, we only went to the next town over once which reduced our gas consumption, the gas bill was only $18 for the water heater, the electric bill didn't process until today for some reason, and other spending was pretty low for us. Almost a spend-nothing month (by accident). The net result was a 96.6% true savings rate (or 108% based on average monthly income).
Don't be too impressed though, because our average savings rate is only 38.6%. Thanks to the electric bill 'migration' into the next month and needing groceries again, this month's savings rate will be much lower.
