Fixes inaccurate monthly depreciation value displayed at depreciation report when using a floor value

[iryadifarhan]

Hello there! So apparently, I'm laying my hands on the code around reporting and stumbled upon this bug.

And.. yes, I have tested this on the demo website, and it appears to still be there :0

Here, I would give the exact steps (preconditions) on how I reproduce the bug, and also my proposed solution.

Feel free to adjust if it's not quite well!
Thanks!

Preconditions 📝

• I have an asset with information as below
  

Current date when testing this was 26th November 2025, so the asset would fully depreciate at 1st of December 2025

• Depreciation type being used is defined as below
  
• System is using linear method
  

Bug 🐛

On Depreciation Report page, it displayed an inaccurate value for Monthly Depreciation as DepreciationReportTransformer ignores the floor value!
*based from Straight-line Depreciation calculation

Proposed Solution 💡

Utilize defined formula at parent class app\Models\Depreciable.php

public function getMonthlyDepreciation()
{

    return ($this->purchase_cost-$this->calculateDepreciation())/$this->get_depreciation()->months;

}

Fixed Result ✅
