Starts running out of money yet having plenty to spare (5)

I believe the answer is:

roomy

I'm a little stuck... Click here to teach me more about this clue!

'plenty to spare' is the definition.
I can't tell whether this definition defines the answer.

'starts running out of money yet' is the wordplay.
'starts' indicates taking the first letters.
The first letters of 'running out of money yet' is 'ROOMY'.

'having' acts as a link.

Can you help me to learn more?

(Other definitions for roomy that I've seen before include "Not cramped" , "Without cramping" , "Spaced-out" , "Voluminous" , "Capacious" .)

I've seen this clue in The Irish Times.
