Overloaded on the rear axle? It works out how far the load has to move to bring both axles inside your limits.
Load position to axle weight
Where you put the weight matters as much as how much you carry. Axle Load Calculator works out how a load sitting on your bed or trailer divides between the axles, so you can see an overload before the weighbridge does.
SET THE VEHICLE UP ONCE
Enter the wheelbase, and the weight each axle already carries when the vehicle is empty. Add the limits from your vehicle plate. That is the whole setup, and it is ready for every load after that.
ADD THE LOAD BY WEIGHT AND POSITION
Each item goes in as a weight and a distance. The moment you place it, you see how much of it lands on the front axle and how much on the rear, and every bar fills toward the limit you entered. Green while there is room, red once there is not.
THE PART THAT SAVES THE TRIP
When an axle goes over, the app does not stop at telling you so. It solves for how far the load has to move — forward or back — to bring every axle inside its limit, and shows the distance in centimetres or inches. One tap shifts the whole load by that amount so you can check the result. If the total is simply too heavy to fix by moving it, the app says that instead, and works out roughly how much has to come off.
TONGUE AND HITCH LOADS
A trailer is the same lever, measured from the coupling instead of the front axle. The app shows the share landing on the hitch both in weight and as a percentage of trailer weight. Loaded too far back, a trailer lifts the coupling and starts to sway. Too far forward, it presses down on the tow vehicle's rear axle. Pick your tow vehicle and you can see exactly what the trailer does to its axles.
BUILT ON ARITHMETIC, NOT GUESSWORK
An item over the front axle is carried entirely by the front axle. Over the rear axle, entirely by the rear. Anywhere between, it splits in proportion to distance — the same balance of moments that decides a see-saw, and the same one a weighbridge measures. There are no invented correction factors anywhere in this app.
LIMITS ARE YOURS TO ENTER
Axle limits are written into your vehicle plate and into the road rules where you drive, and they differ from country to country. This app will never tell you what your legal limit is. You enter it, and the app tells you whether the load fits.
ALSO IN THE APP
- Kilograms and metres, or pounds and feet
- Several vehicles and trailers, saved side by side
- Turn any item off to test loading without it
- Combined centre of gravity marked on the side view
- Works entirely offline. No account, no tracking, no network access at all — everything you enter stays on your device
A PLANNING TOOL, NOT A CERTIFICATE
This app estimates from the numbers you type in. Real axle weights also depend on the true weight of each item, how the load settles, the road surface and the state of the suspension. It is a way to load thoughtfully and to know when a weighbridge trip is worth it — never a substitute for the certificate one gives you.
One purchase. No subscription, no adverts, no in-app purchases.
Set the vehicle up once
Enter the wheelbase, the empty axle weights and the limits from your vehicle plate. That setup is then ready for every load after it.
Add items by weight and position
Each item goes in as a weight and a distance. You immediately see how much lands on the front axle and how much on the rear, with every bar filling toward the limit you entered.
It tells you how far to move the load
When an axle goes over, the app solves for the distance the load has to shift — forward or back — to bring every axle inside its limit. If the total is simply too heavy, it says so and works out roughly how much has to come off.
Tongue and hitch loads
For trailers, the share landing on the coupling is shown both in weight and as a percentage of trailer weight. Pick your tow vehicle to see what the trailer does to its axles.
Arithmetic, not invented factors
An item over an axle is carried by that axle; anywhere between, it splits in proportion to distance — the same balance of moments a weighbridge measures. There are no correction factors anywhere in this app.

Kilograms and metres or pounds and feet, several vehicles and trailers saved side by side, and no network access at all.
Does the app know my legal axle limits?
No, and it never will. Axle limits come from your vehicle plate and from the road rules where you drive, and they differ from country to country. You enter them, and the app tells you whether the load fits.
Can I use this instead of a weighbridge?
No. This is a planning tool that estimates from the numbers you type in. Real axle weights also depend on the true weight of each item, how the load settles, the road surface and the state of the suspension. Use it to load thoughtfully and to know when a weighbridge trip is worth it — never as a substitute for the certificate one gives you.
How does it decide the split between axles?
By the balance of moments. An item sitting over the front axle is carried entirely by the front axle, one over the rear entirely by the rear, and anywhere between it divides in proportion to distance — the same lever arithmetic that decides a see-saw.
Does it work without a network connection?
Yes. The app works entirely offline. There is no account, no tracking and no network access at all.
