Scots must pay £12.546 billion every year just to stay in the Union according to Office of National Statistics (ONS) information. UK public sector net borrowing (excluding financial interventions) was £139.4 billion in the year 2010/11 and so Scotland's share based on 9% population amounts to £12.546 billion.
This is at least the annual cost for Scots of remaining within the Union as Scotland's national accounts show a surplus meaning none of the debt is accrued in Scotland.
According to world-renowned economic expert Professor Andrew Hughes Hallet Scotland's economy, unlike the UK economy is in robust shape:
“Scotland’s accounts, rather than those compiled in London, show that Scotland has a small net surplus, rather than being a net beneficiary from the UK."
The bad news for Scots is that the UK treasury is accruing debt which is accelerating owing to bad house-keeping south of the border and dragging the Scottish economy down with it.
