Well, that's kinda depressing - but maybe everyone is just trying to tactfully ignore the elephant
You appear to have had a bit of a typo with your maths - could be a misplaced decimal point - and also mixed up income and outgoings?
The TOTAL outgoings for the last three years was £91,234
You did a three year income/outgoing differance calculation, but seem to have moved the decimal point/s leftwards for the 2015 values?
£28,592 = Income last three years
£91,234 = Outgoings last three years
£62,642 = Difference (NOT £49,472.87)
For those interested here's the run down for the last 11 years, missing one year, which helps to show the build-up of capital:
