How the calculation works
Net profit = quantity × (sell − buy) − buy charges − sell charges − estimated tax.
Worked example
10 shares bought at 500 and sold at 550, with zero entered charges and tax, produce NPR 500 profit. Zero costs are an illustration, not a fee recommendation.
Assumptions and limitations
Tax is applied to positive estimated gain after entered costs. Your broker or tax authority may use a different taxable basis.
