Formula Used
The calculator keeps each modifier visible so Dungeon Masters can audit the result.

How to Use This Calculator
Follow these steps to build a complete character, mount, or party load assessment.
- Enter the character’s Strength score, creature size, and normal walking speed.
- Select standard, variant, or custom encumbrance rules.
- Add special size or capacity modifiers granted by species traits, magic, feats, forms, or house rules.
- Enter any manual weight that is not represented by an inventory row.
- Add equipment to the inventory table. Choose external or extradimensional storage when the item should not count.
- Enter coins and decide whether coin weight is active.
- Add containers, including empty weight, contents, limits, and extradimensional behavior.
- Add mounts, companions, vehicles, or pulling groups when the party distributes cargo.
- Press the calculation button. Review capacity, remaining weight, speed, active penalties, and warnings.
- Save locally, export a JSON backup, download the inventory as CSV, print the summary, or copy a share link.
Understanding carrying capacity
Carrying capacity represents the weight a creature can normally carry without relying on the special push, drag, or lift allowance. Under the common rule, a Small or Medium creature’s carrying capacity equals fifteen times its Strength score in pounds. Tiny creatures use half that amount, while each size category above Medium doubles the capacity. The calculator applies size before special modifiers and then adds any fixed bonus.
Standard and variant encumbrance
Standard rules keep the calculation simple: compare the total load with normal carrying capacity and the separate push, drag, or lift limit. Variant encumbrance introduces lower thresholds. A load above five times Strength is encumbered, and a load above ten times Strength is heavily encumbered. The 2014 variant also imposes ability, attack, and saving throw disadvantages while heavily encumbered. Custom mode lets a Dungeon Master replace those thresholds and speed reductions.
Containers and extradimensional storage
A mundane container normally contributes its own empty weight plus the weight of its contents when the character carries it. An extradimensional container can be modeled by enabling its extradimensional option. The calculator then counts the container’s empty weight but excludes its contents from the character’s carried total. Capacity warnings remain visible so the user can still detect an overfilled container.
Mounts and vehicles
Mount and vehicle rows are calculated separately. Each row accepts Strength, size, number of pulling creatures, cargo, passengers, a vehicle bonus, and a custom multiplier. The result helps a party compare loads, but unusual harnesses, terrain, creature traits, and vehicle rules may require a Dungeon Master’s decision.
Accessibility and practical use
Status is communicated with written labels as well as colors. Tables can be used with a keyboard, every major control has a visible label, and the print view removes editing controls. Saved data stays in the browser’s local storage unless the user exports it. JSON exports contain form values, so users should review files before sharing them publicly.
