We earned $197k after tax in salary, business related refunds, medical payment refunds, tax refunds etc. We earned (including unrealised capital gains) $37k on non-retirement account investments. $10k of the latter was just due to the fall in the Australian Dollar. The investment number is pre-tax. Total after tax income was $233k. We spent $151k but only $92k of that was "core spending". So, I always regard business expenses that are refunded as non-core, but also some one-off things. The biggest of these was stamp duty for buying our house of $27.8k and then $13.5k of gardening. So, that is 2/3 of the non-core expenditure. Then there were moving and settlement costs.
$7.5k 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 tot he change in net worth. Then there was $1k of excess contributions I made to superannuation (not by choice) that had to be withdrawn... Finally, we transferred $194k in down-payment, mortgage payments, and some building work to the housing account. The change in current net worth, was therefore -$119k. Looking at just saving from non-investment income, we saved $148k.
The retirement account is a bit simpler. We made $41k in after tax contributions and the value rose by an estimated additional $67k in pre tax returns. $7k was the estimated tax on that and so the increase in net worth was $100k. Taxes are just estimated because all we get to see is the after tax returns.
Finally the housing account. We spent $19.5k on mostly mortgage interest. We saved about $4k in mortgage interest by keeping money in our offset account. Actually that $4k was part of our "current investment return". So we have to deduct the notional spending here to balance the books. I estimate our house is worth $10k more than we paid for it based on a recent sale in our neighbourhood. So that is an investment gain. We transferred the $194k into our housing account. So housing equity rose $181k with $171k of it being transfer of savings from our current account.
In total, net worth rose $163k, of which $63k was savings from retirement contributions and saving from current earnings.
