is it (100/150 000) x 230 000 = 153%

^ + 1

or

(230,000-150,000)/150,000 = +53%

As above.

I remember with this simple process for calculations regarding percentages. Works for any percentage calculation, or value calculation based on a percentage difference.

£150,000 = 100% (last years total)
£230,000 = x

X always to the top so...

£230,000 = x
£150,000 = 100%

Make a little equation as you see it. Divide the two known values that sit one atop the other and and multiply by the third.

(230,000 / 150,000) x 100 = 153.33

So a 53.33% uplift.

The other way round, just to demonstrate... Calculate 53.33% increase in last years revenue.

150,000 = 100%
X = 153.33%

(153.33 / 100) x 150,000 = 230,000.

Anyway, works for me so hope it helps you...

Impressive projections, but you flustered, and if you can't do simple sums then I'm afraid I can't work with you.
I'M OUT!

Try changing your question into maths then solve the equation...

What is the percentage (P) increase on 150,000 to get 230,000?
Translates as. P x 150000 = 230000
P. = 230000 / 1500000

Don't forget to keep your equals signs lined up like your maths teacher told you to!

If my figures don't impress then I will resort to my impressive projection.
