As a rule of thumb,  add one mile of enroute distance for each
1000 feet of climb.  As an example, if your distance is 100 miles,
and your climb is 5000 feet, figure time, fuel burn, and the like 
for a trip of 105 miles.  This trick works best for cruise climb,
and is accurate to 1 minute or so and 1 or 2 gallons.  Many precision
pilots use this trick.

However, if you like playing test pilot, you can probably, in enough
flights, build your own tables for your own technique.
