Variables & Legend
Step-by-Step Calculation
- Annual Payout Escalation:
Monthly Payout_y = Monthly Payout_1 × (1 + g)^(y-1)Every 12 months, the monthly withdrawal steps up by your inflation target percentage.
- Month-by-Month Compounding & Depletion:
Balance_m = (Balance_{m-1} - Withdrawal_m) × (1 + r/12)Withdrawals are disbursed monthly, and the remaining capital continues compounding at the portfolio return rate.
- Depletion & Longevity Verification:
Check if Balance_m ≤ 0 at any month m within TenureTracks the exact year and month when capital exhausts or confirms portfolio solvency.
