Bundle Cost & Margin Calculator

Visualize front/rear and left/right imbalance quickly (education/self-check)
Enter weights in four zones to see imbalance and improvement guidance. Includes axle load estimation with templates.
This tool is a simplified estimate. Not a substitute for weighing or legal checks.
Quick start
Vehicle template
Selecting a template changes the input grid and result display automatically. Need axle-by-axle estimates?
ඒකකය
0 is OK. Empty is treated as 0. No negatives.
Zone input
Select item and weight to auto-add to zone totals.
Item (optional) Weight Zone
詳細設定
Adjust thresholds and axle assumptions to match your rules.
Front/rear can be slightly looser than left/right.
Left/right is often more noticeable; tighter thresholds are common.
Axle load estimate (optional)
Only for 2-axle template. Assumes zone weight at zone centers.
Shows an overload warning when exceeded.

Improvement actions

If imbalance appears, adjust load as suggested and re-check.

Axle load estimate
Estimate assuming zone centers. Not a measured value.
Results are estimates. Not a substitute for measurement or legal checks.

How to use (3 steps)

• Select a template
• Enter weights by zone
• If imbalance appears, move load and re-check
• Front/Rear: roughly split the bed into front half / rear half
• Left/Right: split by vehicle centerline

Why imbalance matters

Unstable handling

Large imbalance can affect handling and braking distance.

Wear on suspension

One-sided overload concentrates stress on tires and suspension.

Load shift/damage

Higher or uneven center of gravity increases shift/damage risk.

Criteria (simplified)

• Left/Right difference: 0–5% OK / 5–10% Caution / 10%+ Alert
• Front/Rear difference: 0–10% OK / 10–20% Caution / 20%+ Alert
• Adjust thresholds in Advanced settings to match your rules

Vehicle templates (axle details)

This tool checks front/rear and left/right balance with minimal input. For axle estimates, switch to 3-axle or tractor/trailer templates.

නිතර අසන ප්‍රශ්න

Can I enter axle details?

Yes. Select 3-axle or tractor/trailer templates to display axle load estimates. These are simplified and not a substitute for measurement or legal checks.

How accurate is it?

This is a simplified estimate based on zone inputs. Actual weighing takes priority.

Is rough input still useful?

Yes for education and imbalance detection. For high risk, proceed to measurement.

Can I save values?

Last inputs can be saved in the browser (local only), and URL sharing is available.

My load spans multiple zones

Split the weight proportionally (e.g., front 30% / rear 70%).

Important notice

• This tool is for education/self-check only
• Prioritize weighing, vehicle specs, regulations, and transport contracts
• Load securing and protection are still required
• It does not guarantee road legality
