For illustration purposes let’s take examples of full grown trees with different volumes of olives and different ratios of olive/olive oil:
A) 40 kg per tree yielding 20% oil:
40 x 36 trees per dunam = 1440 kilos x 20% = 288 liters of oil. Today’s high quality boutique Suri olive oil sells for NIS 50 per liter. 288 x 50 = NIS 14,400 and now divide it by 3.55 (dollars) and you have $4,056 x .25 (buyer’s percentage) = $1,014 to the buyer(s) for a dunam.
If the buyer paid for all included $27,000 all included for a dunam this would be an apx. 3.75% return for the year.
B) 70kg per tree yielding 22% oil:
70kg x 36 trees per dunam = 2,520 kilos x 22% =554 liters of oil x NIS 50 per kilo = NIS 27,700 divided by 3.55 = $7,802 x .25 = $1,950 to the buyer of a dunam.
Same purchase price as A means an annual yield of: 7.2%
Over the first few years, this certainly isn’t an attractive investment. However, if you take the benefits of what the work is doing for Israel and the Jewish People and combine it to when the trees are more mature, you should have an important income producing asset.
