Combine pension value, Social Security, lifetime annuities, 401(k)/403(b)/TSP assets, IRAs, Roth accounts, taxable investments, and cash into one forward-looking retirement balance sheet. The tool estimates both economic wealth and how much of a retirement spending target may be covered by lifetime income.

At age 65, modeled guaranteed income covers approximately 39.9% of the projected spending target. The remaining first-year funding need is $54,318, equal to 4.8% of projected investable assets.
Approximately 57.6% of modeled economic retirement resources are represented by lifetime-income equivalents and 42.4% by investable or liquid assets. The guaranteed-income portion is an economic value—not cash available for immediate withdrawal or inheritance.

For an already-active pension or annuity, “Annual amount used” is the current amount entered. For a future benefit, it is the expected first-year amount.
This tool is designed as a retirement economic balance sheet: it places investable assets and the present value of lifetime income on the same planning page while keeping their very different liquidity characteristics visible.
A 401(k), IRA, Roth account, brokerage account, and cash reserve are assets that can generally be invested or liquidated subject to plan, tax, and market constraints. A pension or Social Security benefit is different: it is a stream of future payments. The calculator converts those payments into an estimated present value so the income stream can be viewed beside the portfolio without pretending that it is spendable cash today.
When a pension or annuity value is not entered, the calculator estimates the value of the remaining future payments month by month. Each projected payment is multiplied by the probability that the beneficiary is alive to receive it and then discounted back to today using a maturity-matched Treasury-rate proxy.
This is a planning estimate, not an insurer quote, pension-plan lump-sum calculation, or actuarial certification.
A start age earlier than current age is valid. In that case, the tool assumes the benefit is already being paid and values only future payments from today forward. For a pension or annuity already in payment, enter the current annual amount. The model does not add payments already received and does not attempt to recreate historical cost-of-living adjustments.
For Social Security already in payment, use the current monthly benefit and select Current / 2026 dollars.
Level benefits remain unchanged in nominal dollars. Fixed COLAs compound at the entered percentage. CPI-linked benefits use the embedded CPI-W planning path, while a capped CPI option applies the lesser of projected CPI-W or the selected cap. Inflation therefore affects both future income and the purchasing-power comparison.
Current investable assets are projected to the selected retirement age using the entered constant annual return. Annual contributions are modeled at year-end. This is a deterministic projection: it does not simulate market volatility, sequence-of-returns risk, fees, or changing contributions.
The annual spending target is first projected from 2026 dollars to the retirement analysis age. The calculator then subtracts modeled pension, Social Security, and annuity income that is active at that age. Any remaining gap is the first-year amount that must come from investable assets.
The headline “guaranteed-income share” is the percentage of total modeled economic resources represented by the present-value equivalents of pension, Social Security, and annuity income. A high percentage can indicate that much of the household’s retirement resources are tied to lifetime income rather than liquid assets; it does not, by itself, imply that the investment portfolio should take more or less risk.
The calculator is gross and pre-tax. It does not model federal or state income taxes, taxation of Social Security, required minimum distributions, pension funding status, PBGC limits, insurer credit risk, surrender charges, investment fees, sequence risk, long-term-care costs, or a personalized life expectancy. These factors can materially change a retirement decision.
Use the results as a structured planning framework, then compare them with plan documents, official Social Security estimates, and professional financial, tax, or actuarial advice when the stakes are significant.
The mortality inputs use the 2026 static male, female, and unisex tables embedded in the calculator. Discounting uses the Treasury par-yield curve dated August 12, 2026, with linear interpolation between published maturities and the 30-year rate held constant beyond 30 years. CPI-W planning assumptions use the 2026 Social Security Trustees’ intermediate annual CPI path of 2.62% for 2026, 2.46% for 2027, and 2.40% thereafter.
Treasury par yields are used as a transparent maturity-matched discount-rate proxy. A formal actuarial or institutional valuation may use a different discount framework, a bootstrapped spot curve, plan-specific mortality, or other assumptions.
