Use any of the online databases for the information. They are usually correct *most* of the time.

EXPGAINED = Ceiling( BASEEXP * (0.001 * QUALITYGAINED + 1) )
where EXPGAINED = what you see on screen
QUALITYGAINED = Self-explanatory
Ceiling = Round up to nearest whole number

Relative Recipe Rank/Base EXP table

-21	-20	-19	-18	-17	-16	-15	-14	-13	-12	-11	-10	-9	-8	-7	-6	-5	-4	-3	-2	-1	0	1	2	3	4	5	6	7	8	9	10
0	0	0	15	20	25	30	40	50	75	100	125	175	225	275	325	375	400	425	450	475	500	600	700	800	900	1000	1100	1200	1300	1400	1500

E.g. A recipe of the same rank will give you 500 base exp.
