Personal Financial Life Plan & Retirement Model – Excel XLSX

BENEFITS OF THIS DOWNLOADABLE EXCEL DOCUMENT

1. Change any assumption and every number recalculates -- year-by-year household cash flow, net worth and retirement readiness in pure Excel formulas.
2. A built-in Monte Carlo simulation re-runs your plan across 250 paths and shows the spread of outcomes as P10, P50 and P90 -- it ships deterministic, so you switch it on with one cell on the Assumptions tab.
3. Includes a loan and mortgage module and an optional tax rate, with no macros, no add-ins and no subscription; tested in Excel 2016+ and Microsoft 365.

RETIREMENT EXCEL DESCRIPTION

Personal Financial Life Plan & Retirement Model is an Excel template (XLSX) available for immediate download upon purchase.

Personal Financial Life Plan & Retirement Model – a fully editable, year-by-year Excel projection of your household cash flow, net worth and retirement readiness, from your current age to the life expectancy you set. Now with a loan/mortgage module, an optional tax rate, and a built-in Monte Carlo simulation.

Change any assumption and every number recalculates. Built entirely in Excel formulas – no macros, no add-ins, no subscription. Tested in Excel 2016+ and Microsoft 365; there are no macros to break, so it should also open in Google Sheets and LibreOffice Calc, but neither is tested and charts are the part most likely to need rebuilding there.

WHAT IT DOES
•  Projects income, expenses, investment returns and your asset balance year by year, from your current age to your chosen life expectancy.
•  Shows the headline results that matter: assets at retirement, the age your money would run out (if ever), the lowest balance along the way, and your plan-end position.
•  Three return scenarios – cautious, base and optimistic – side by side, plus an interactive dashboard with net-worth charts, key metrics and your asset CAGR.
•  Monte Carlo (Lite): re-runs your plan across 250 randomized return paths and shows the spread of outcomes (P10, P50, P90) with a distribution chart. Deterministic by default; flip one cell to randomize, and the same seed reproduces the same paths.
•  Loan and mortgage module: enter amount, rate, term and start age, and the model amortizes the debt and folds the impact into your net worth.
•  Optional effective tax rate applied to investment returns.
•  Handles salary growth, expense inflation, a separate retirement spending level, a second income such as a pension, and up to six one-off events (home purchase, education, downsizing, inheritance, and so on).
