Present value is the organizing principle of the Actuarial Approach recommended on this website. Retirement sustainability ultimately depends on a single question: Can the present value of your assets support the present value of your planned lifetime spending? The ratio of these two quantities — your funded status — provides an actuarially coherent measure of retirement readiness and a disciplined way to monitor financial solvency over time.
Many readers find present value calculations challenging, particularly when applied to long‑range spending plans. The Actuarial Financial Planner (AFP) workbook is designed to handle this complexity for you. All inputs are entered in the Input & Results tab, and the AFP automatically performs the present value calculations in the PVCalcs tab using risk‑adjusted discount rates. These discount rates allow you to compare the present value of non‑risky assets with the present value of essential spending on a consistent basis.
