visa or not

if you earn the £14000 can the shortfall be made up with a percenatage of the required savings ,which are stated as the required amount instead of earnings, in other words a slice of both?

Yes, that's correct.
In this case the shortfall is £4600
Means required savings of 2.5 x £4600 = £11250
That is on top of the minimum £16000
So to meet the income shortfall needs savings of £27250 which must be held for 6 months prior to application.
And that level needs to be shown again at FLR application time 30 months later (held for 6 months prior to application)

Not an easy option, but one that some folks may be able to use.
