We earned $158k after tax in salary, business related refunds, medical payment refunds, tax refunds etc. We earned (pre-tax including unrealised capital gains) $58k on non-retirement account investments. Total current after tax income was $216k. We spent $77k, $71k of that was "core spending". (I always regard business expenses that are refunded as non-core, but also some one-off things).
$9k of the investment income was tax credits. These increased our after tax "other income" but are also counted as part of the pre-tax investment income. So, they have to deducted to get things to add up to the change in net worth. Finally, we transferred $45k in mortgage payments to the housing account.* The change in current net worth, was therefore $85k. Looking at just saving from non-investment income, we saved $36k.
The retirement account is a bit simpler. We made $45k in after tax contributions and the value rose by an estimated additional $54k in pre tax returns. $6k was the estimated tax on that and so the increase in net worth was $93k. Taxes are just estimated because all we get to see is the after tax returns. I do this exercise to make retirement and non-retirement returns comparable.
Finally, the housing account. We spent $20k on mortgage interest. We would have paid $25k in mortgage interest if we didn't have an offset account. I estimate our house is worth $21k more than I did last year based on recent sales in our neighbourhood. After counting the transfer of $45k into the housing account housing equity increased $40k of which $19k was due to paying off principal on our mortgage.
In total net worth increased by $217k, $100k of which was saving from non-investment sources.
Comparing 2016's accounts with the very exceptional 2015 accounts, we saved 56% more and net worth increased by 34% more. Salary and other current income was down as we would expect in a year that Moominmama didn't work (she went back to work yesterday). Of course, she got a lot of maternity and other payments and so current income was only down by 15%. Invesment income was up 18%. Expenditure was down 41% and even core expenditure was down by 18%.
* $5k of this is actually interest we saved by having money in our offset account. I count this as investment earnings and so to balance the books I need to count this as spending on the housing account and need to record a transfer between the current and housing accounts.
