    These tools use mathematical models to illustrate the outcomes generated from the information you enter. Because in the real world markets, tax rules, and personal circumstances can change, the model's results should be viewed as possibilities rather than guarantees. The tools provide projections, comparisons, and potential implications only, and do not constitute personalised advice or recommendations. For specific guidance on investment, pension, or mortgage product decisions, please speak with an FCA-authorised financial adviser. Read full disclaimer
