NumberWalk was created as a contribution to the retirement planning community, built by someone who experienced firsthand the challenges of planning for financial independence.
While NumberWalk offers powerful simulations, we recognize the value of professional financial advisors who provide personalized guidance, tax expertise, and emotional support during financial decisions. This tool complements, rather than replaces, professional advice.
We believe financial planning tools should be accessible to everyone. NumberWalk exists to help people understand the dynamics of retirement planning through interactive modeling, regardless of their wealth level or financial literacy.
The simulations provided are educational tools to help with planning decisions. For comprehensive financial advice tailored to your specific situation, we encourage consulting with a qualified financial professional.
Market crashes are a historical pattern. When one hits early in retirement, your financial plans may suffer. Unlike random simulations, historical testing can provide insight and simulate how they could impact your retirement cash flow, so you can have a plan B or make adjustments if needed.
