Our calculations use standard financial formulas and are mathematically precise. However, the accuracy of projections depends on the realism of your input assumptions, particularly regarding future interest rates and economic conditions.

While the calculator handles regular periodic transactions excellently, truly irregular or one-time transactions are best modeled by running multiple scenarios and combining the results manually.

The adjustments use standard financial modeling approaches. For personalized financial planning, we recommend consulting with a qualified financial advisor who understands your specific tax situation and local economic conditions.
