Frequently Asked Questions

How accurate are these financial estimates?

These calculations use standard financial formulas and are mathematically accurate given your inputs. Real-world results depend on factors the calculator can't predict: market returns, tax law changes, spending behavior, and unexpected expenses. Use these as planning tools, not guaranteed outcomes.

Should I consult a financial advisor?

For major decisions — retirement planning, large investments, debt restructuring — yes. A fee-only fiduciary advisor accounts for your complete financial picture. These calculators are excellent for building understanding and running scenarios but aren't a substitute for personalized advice.

How do taxes affect this calculation?

This calculator uses pre-tax inputs unless otherwise noted. Investment returns, income, and withdrawals are subject to federal, state, and local taxes that significantly change net results. Run your numbers through a tax-aware calculator or consult a tax professional to understand after-tax outcomes.

What assumptions does this calculator make?

Financial calculators typically assume constant rates, regular payment intervals, and no changes to amounts over time. Real scenarios involve variable returns and irregular contributions. Results are most useful for comparing relative outcomes rather than predicting exact dollar amounts.
