What Is Legacy Planning?

Legacy planning is the comprehensive process of determining how your wealth, values, and assets will be transferred to future generations and charitable causes. Unlike basic estate planning, which focuses primarily on legal documents and tax minimization, legacy planning encompasses the broader question of what you want to leave behind — not just financially, but in terms of family values, philanthropic impact, and multi-generational wealth stewardship.

Effective legacy planning requires projecting the future growth of your estate, accounting for inflation, understanding the impact of taxes, and ensuring your assets are structured to achieve your goals. Key components include wills and trusts, life insurance, charitable giving strategies, business succession plans, and family governance structures. Legacy planning also involves preparing heirs to be responsible stewards of wealth through financial education and family communication.

A well-crafted legacy plan balances multiple objectives: providing for heirs, supporting charitable causes, minimizing taxes, preserving family harmony, and ensuring your values are passed down. This calculator helps quantify these goals, identify gaps in your current plan, and assess whether your legacy strategy is on track to achieve its objectives.

Legacy Planning Formula

Projected Estate Value = Net Worth x (1 + Growth Rate - Inflation Rate)^Years

Inflation-Adjusted Legacy = Desired Legacy / (1 + Inflation Rate)^Years

Charitable Gift Total = Projected Estate Value x Charitable % / 100

Per-Heir Inheritance = (Projected Estate Value - Charitable Total) / Number of Heirs

Life Insurance Gap = Max(0, Desired Legacy - Projected Value - Life Insurance)

Example Scenario

A family with $3,000,000 net worth wants to leave a $2,500,000 legacy in 20 years. They have 3 heirs, want 10% to go to charity, expect 6% growth and 3% inflation. They have a moderate plan and $500,000 life insurance.

Projected Value: $3,000,000 x (1 + 0.03)^20 = $5,418,334

Inflation-Adjusted Legacy: $2,500,000 / (1.03)^20 = $1,384,144

Charitable Total: $5,418,334 x 10% = $541,833

Per Heir: ($5,418,334 - $541,833) / 3 = $1,625,500

Life Insurance Gap: Max(0, $2,500,000 - $5,418,334 - $500,000) = $0 (no gap)
