Before you fire up the extractor, it helps to know roughly how much honey is coming off the hive — enough to buy jars, plan sales, and check your colony is hitting its potential. This estimator turns a quick inspection (how many supers, how full the frames look) into pounds of extracted honey and a jar count.
How it works
Honey weight starts from the comb. A fully drawn, fully capped frame holds a known amount that depends on the super depth:
deep ≈ 6 lb/frame, medium ≈ 3.5 lb/frame, shallow ≈ 2.5 lb/frame
Multiply by your supers, frames per super, and the fraction actually capped:
in-comb lb = supers × frames × lb-per-frame × (fill% ÷ 100)
Extraction never recovers it all, so we apply a 92% efficiency for what ends up in the bucket:
extracted lb = in-comb lb × 0.92
Jars come straight from weight: a “1 lb” honey jar holds one pound, an 8 oz jar holds half a pound.
Example
Two deep supers, ten frames each, averaging 80% capped: in-comb is 2 × 10 × 6 × 0.80 = 96 lb, extracting to about 96 × 0.92 ≈ 88 lb, or roughly 88 one-pound jars.
Notes
Be honest about the fill percentage — counting empty edges, brood or uncapped nectar as honey inflates the result. Honey is also dense (about 12 lb per gallon), so the volume looks small for the weight. For an exact figure, weigh each super on a luggage scale before and after extraction. All calculations run locally in your browser.
What drives the variation in real yields
The estimated yield is a planning number — actual results swing widely depending on several factors that the inspector’s eye cannot easily quantify:
Nectar flow strength. A strong midsummer flow in a good forage area can push a deep super past the 6 lb-per-frame average. A weak flow or drought year may leave supers half-drawn and half-capped, dropping yield sharply. Experienced beekeepers track flow strength with hive scales to calibrate expectations before harvest.
Honey moisture content. Bees evaporate water from nectar until the moisture content drops below about 18 to 18.5 percent, then cap the cells. If you harvest uncapped honey the moisture may be too high, leading to fermentation in the jar. Moisture also affects density: wetter honey weighs slightly less per volume. Always check with a refractometer before extracting from uncapped cells.
Draw quality. New foundation that is only partly drawn holds far less than fully drawn, seasoned comb. A deep frame that is only drawn to 70 percent of its depth may yield 4 lb rather than 6. Tracking how well your comb is drawn is a useful habit alongside tracking fill percentage.
Extractor efficiency. Tangential extractors leave more honey in the comb than radial ones. A honey gate left open too long, warm uncapping rooms, and cold-extracting all affect the percentage you actually collect. The 92% efficiency default in this estimator matches typical radial extraction; adjust it downward for tangential or very cold conditions.
Planning jars before you harvest
Knowing your expected yield before harvest day saves a last-minute rush for containers. As a rough guide: one pound of honey fills a US pint jar about two-thirds of the way (honey is denser than water, at roughly 1.4 g/mL). A 1-lb queenline or hex jar holds exactly 1 lb, an 8-oz jar holds half a pound. If you are selling at farmers markets, 12-oz and 16-oz bears and hexagons are common sizes — divide your extracted-pound estimate by the jar weight to get your count before purchasing lids and labels.
