What does a litre of coconut sap
cost with SAPER?

Move the sliders to see how SAPER brings the cost of producing sap down by half or more. Values are starting-point assumptions; replace them with your own field numbers.

Farm size
SAPER devices one worker looks after
Pick this first. 500 is the default; labour cost, manpower and climbs below are worked out for the number you choose.
Currency
Today (manual tapping)
Per litre — current minimum market price
Litres — assumption, use your field average
SAPER device
Device life
Kept at 0% to be conservative
Allows for changeover gaps between flowers
Blades, sanitiser, battery wear (assumption)
Labour
Set automatically from the device count above (devices ÷ days on one flower); move it to work with your own figure. The worker never cuts the flower. Each day they prepare new flowers and fit SAPERs on them; every device then taps on its own until that flower is finished.
Used to compare manpower. Each tree usually needs 3 dangerous climbs a day.

How the maths works

Manual cost is taken as the current sap price, since tapper wages make up most of it. Interest on the device and transport are not included. Figures are estimates, not guarantees.
