3. Common Mistakes to Avoid

  • ⚠Dividing total inclusive price by tax rate decimal instead of 1 + tax rate.

6. Methodology, Assumptions & Limitations

Calculation Engine: DexCalc models financial metrics deterministically using standard algebraic financial formulas verified by corporate finance professionals.

Compounding & Inflation Assumptions: Unless custom compounding flags are set, interest growth models assume standard periodic compounding (monthly or annual). Inflation drag, tax bracket indexation, or asset market volatility are modeled linearly based on user inputs.
