The question

How should a farm compare fertilizer prepay with spot buying?

Begin with one dated worksheet and record cash timing, finance cost, delivery assurance, storage exposure, and the quantity that remains open. That makes assumptions visible before the next call or operating decision. Keep this limit in view: neither prepay nor spot can be assumed to outperform before actual terms and later prices are known.

What matters now

  1. Make the comparison apples-to-apples by documenting cash timing, finance cost, delivery assurance, storage exposure, and the quantity that remains open.

  2. Keep every cited number tied to its unit, geography, reference period, release date, and revision state.

  3. Use the result to ask a better local question, not as a prediction; neither prepay nor spot can be assumed to outperform before actual terms and later prices are known.

Before the next call

What to check

  • Check that the comparison uses like units, locations, and delivery or reference periods.

  • Check each official release date and whether the underlying value is preliminary, revised, suppressed, or missing.

  • Check that the decision record states this limitation: neither prepay nor spot can be assumed to outperform before actual terms and later prices are known.
