Groundnut Shelling & Your True Kernel Out-turn
Shells pods
Enter your pod weight and shelling percentage to get the kernel out-turn, shell by-product, pod-to-kernel ratio and kernel value — your real saleable peanut weight.

Next: expect ~700 kg kernel + 300 kg shell; dry pods to ~8% moisture before shelling, and sell shell as fuel/feed.
Out-turn varies by variety, pod fill and moisture; sound, bold kernels grade higher for seed/oil.

Sell the kernel, not the pod weight
A heap of groundnut pods is not what the buyer pays for — the kernel inside it is. Pods shell to kernel at roughly 68–72% by weight, so nearly a third of what you weigh at harvest is shell. Knowing your shelling recovery turns raw pod weight into the figure that matters: how many kilograms of saleable kernel you actually have, and what they are worth at your grade's rate.
This tool gives the kernel kilograms, shell weight, pod-to-kernel ratio and kernel value from your pod weight and shelling percentage. Dry pods to about 8% moisture so they shell cleanly with less breakage, run a quick test shelling to confirm your percentage, and value the lot on clean kernel. Pair it with the Oil Extraction Yield and Value Addition Profit tools to see the full return from your crop.

Frequently Asked Questions
What is groundnut shelling recovery?+
Shelling recovery (or out-turn) is the share of pod weight that becomes kernel after the shells are removed. Groundnut pods typically shell to kernel at about 68–72% by weight, so 100 kg of pods gives roughly 68–72 kg of kernel and the rest is shell. The recovery figure is what decides your saleable peanut weight.
How is shelling recovery calculated?+
Kernel kg = pod weight × shelling percentage. Shell kg = pod weight − kernel kg. For example 100 kg of pods at 70% shelling gives 70 kg of kernel and 30 kg of shell. The pod-to-kernel ratio is pod weight ÷ kernel weight — around 1.4–1.47 for a 68–72% recovery.
What is a good shelling percentage for groundnut?+
Most groundnut shells out at 68–72% kernel by weight. Well-filled, mature, properly dried pods sit at the top of that range; immature, pest-damaged or poorly filled pods shell lower. The variety and grade matter too — bold-seeded types often give higher recovery than small-seeded ones.
Why does moisture affect shelling?+
Pods dried to around 8% moisture shell cleanly with the least breakage and the truest kernel weight. Pods that are too wet shell poorly and split kernels; over-dried pods can also crack kernels. Drying to the right moisture protects both recovery and kernel grade, which is what the buyer pays for.
Is the shell worth anything?+
Shell is a by-product, not waste. It is widely used as boiler fuel, livestock feed filler, mulch, particle board and as a base for briquettes. While it earns far less than kernel, selling or using the 28–32% of pod weight that is shell adds to the overall return from the crop.
What sets the kernel price?+
Kernel grade and oil content set the price. Bold, uniform, undamaged kernels with high oil content fetch a premium for oil milling or table use; small, split, discoloured or aflatoxin-affected kernels are heavily discounted. Good drying and clean shelling protect both grade and value.
What is the pod-to-kernel ratio?+
It is how many kilograms of pods you need for one kilogram of kernel — pod weight ÷ kernel weight. At 70% recovery the ratio is about 1.43, meaning roughly 1.43 kg of pods per kg of kernel. A lower ratio means better recovery and more kernel from the same pod harvest.
Does this work for any quantity or unit?+
Yes — enter your pod weight in kilograms, quintals or tonnes and the tool scales kernel, shell, ratio and value to match. The shelling percentage you set drives the split, so use a figure from your own test shelling for the most accurate out-turn.
How do I estimate kernel value?+
Multiply the kernel kilograms by the rate per kg for your grade. Because grade and oil content swing the price, run a quick test shelling to confirm both recovery and kernel quality before you negotiate, and quote on clean, dried kernel rather than raw pods.
Are the figures precise?+
They are solid planning figures. Real recovery varies with variety, maturity, drying, pest damage and shelling method. Do a small test shelling on a known pod weight to confirm your own percentage, then use this tool to scale the whole lot and value it.
