Dungeon Settlers Food Calculator

The arithmetic

Use the same food units for stock, production, consumption and reserve. Production and reserve are optional: leaving either blank means zero. The three original inputs are still required.

• daily consumption = settlers × food per settler per day
• available stock = food stock − expedition reserve
• daily net change = daily production − daily consumption
• days remaining = available stock ÷ daily food loss

Days remaining applies only when consumption exceeds production. Otherwise, the calculator shows no projected depletion, including when consumption is explicitly zero. Zero available stock with a daily deficit is already depleted; zero stock with balanced or growing production still has no buffer against gaps in supply.

For each 3, 7, 14 and 30 day horizon, food shortfall is the daily food loss multiplied by the number of days, minus available stock, with a minimum of zero. Extra food per day divides that shortfall by the horizon: it is the additional daily production needed above the production you entered, starting now, to cover that period.

These are constant-rate planning estimates, not a simulation of meals, harvest timing, spoilage or changing settler needs. A zero shortfall is not a guarantee that food arrives before each meal. Refresh the inputs whenever conditions change.

Reading the warning states

Three and seven days are thresholds this site uses to make the output readable — they are not values pulled out of the game, and they are not a claim about when starvation begins.

Why there is no default consumption rate

Consumption per settler is the one number that decides everything else here, and it is exactly the sort of value an Early Access build rebalances. Rather than ship a plausible-looking default that quietly makes every result wrong, this calculator asks you for it.

How to measure it in your own build

It takes one in-game day and gives you a number that is true for the build you are actually playing:

1. Stop anything that adds food. No harvesting, no cooking, and no expedition unloading a haul during the window. Incoming food is what ruins most measurements.
2. Write down two things: your total food, and how many settlers are in the settlement.
3. Let exactly one full in-game day pass. A partial day gives a partial answer.
4. Write down the total food again.
5. Divide. (food before − food after) ÷ settlers is your food per settler per day.

What throws the number off

• A changing settler count. Someone arriving or leaving mid-measurement makes the divisor wrong. Repeat the day if the count moved.
• Farms producing during the window. Any harvest lands in the same pool you are measuring and makes consumption look lower than it is.
• A party on an expedition. Settlers who are away may not draw from the settlement stock at all, so count who is actually home.
• An unusual settlement state. If people are starving, idle or otherwise not behaving normally, measure again once things have settled.

Run it across two or three separate days and average the results. One clean day beats three sloppy ones, but three clean days beat one.

Setting food aside for an expedition

Enter the amount of your current food stock you want to keep out of the settlement forecast. The reserve is deducted once at the start, not every day, and it cannot exceed the current stock. If you have already removed that food from the stock number you entered, do not reserve it a second time.

This is a food-stock allocation, not a ration count. No food-to-ration conversion or expedition requirement is assumed. Check the figures in your build, then record your intended supplies in the expedition planner. The settlement guide covers the production side — farms, dining areas and the buildings that turn raw crops into something useful.
