Beef Jerky Yield & Time Calculator

Jerky shrinks to roughly a third of its raw weight as moisture cooks off, so enter the finished weight you want and we will reverse-engineer the raw beef, drying time, and cost.

Why Beef Jerky Shrinks So Much

Fresh lean beef is roughly 60 to 65 percent water. Dehydrating drives almost all of that moisture off until the meat is shelf-stable and chewy, which is why a hefty raw roast collapses into a modest pile of jerky. For very lean cuts like eye of round you should plan on about a 3.5:1 ratio: 3.5 pounds of raw beef yields about 1 pound of finished jerky. Leaner means more shrink, because fat does not dehydrate the way water does, so a fattier flank trim lands closer to 2.6:1.

How We Estimate Raw Weight and Time

This calculator works backward from the finished weight you want. It multiplies your target by the yield ratio for your chosen cut to get raw pounds, then estimates dehydrator time from slice thickness at a food-safe 160°F.

Raw beef = Finished weight x Yield ratio (2.6 to 3.5)

Slice Thickness Drives Drying Time

Thickness matters more than total batch size. Thin slices around 1/8 inch dry in 4 to 5 hours, medium 3/16-inch strips take 5 to 7 hours, and thick 1/4-inch pieces can need 7 to 9 hours. Slice against the grain for tender jerky or with the grain for a chewier classic texture, and aim for even thickness so the whole tray finishes at once. Jerky is done when it bends and cracks but does not snap clean in two.

Frequently Asked Questions

How much raw beef do I need for a pound of jerky?
For very lean cuts like eye of round, plan on about 3.5 pounds of raw beef per finished pound. Fattier cuts shrink less, so a flank or fattier trim may only need around 2.6 pounds for the same finished pound.
How long does beef jerky take in a dehydrator?
At 160 degrees Fahrenheit, thin 1/8-inch slices dry in roughly 4 to 5 hours, while thick 1/4-inch strips can take 7 to 9 hours. Check it every hour near the end, since exact time depends on humidity, marinade moisture, and how full your trays are.
How do I know when jerky is done?
Finished jerky should bend and crack but not snap completely in half, and it should show no moisture beads when you tear a piece. If it is still soft or shiny inside, it needs more time, because under-dried jerky can spoil quickly at room temperature.
Is homemade jerky cheaper than store-bought?
Usually yes. Store jerky often runs $2.50 to $4.00 per ounce, while a $7.99-per-pound lean roast yielding at 3.5:1 lands near $1.75 per finished ounce. Watch for sales on round cuts to push your per-ounce cost even lower.

Practical Guide for Beef Jerky Yield & Time Calculator

The single biggest cost lever is your cut. Eye of round, top round, and sirloin tip are lean, affordable, and slice cleanly, which is exactly what you want for jerky. Trim every visible bit of fat before drying, because fat will not dehydrate and can turn rancid, shortening how long your batch keeps.

Marinating overnight adds flavor but also adds moisture, so pat strips dry before they hit the trays or they will need extra time. A consistent 160 degrees Fahrenheit is the food-safe target the USDA recommends to knock out bacteria while the meat dries, so resist the urge to run cooler just to save energy.

Store finished jerky in an airtight container or vacuum-sealed bag. At room temperature properly dried jerky keeps one to two weeks, in the fridge a month or two, and in the freezer up to a year. Toss in an oxygen absorber for longer storage and label the bag with the date you made it.

Quick Checklist

  • Pick a lean cut (eye of round, top round, sirloin tip) and trim all visible fat.
  • Slice an even thickness; freeze the beef 1 to 2 hours first for cleaner cuts.
  • Pat marinated strips dry before loading the dehydrator trays.
  • Dry at 160 degrees F until pieces bend and crack but do not snap clean.
