firenum.com has released five FIRE planning spreadsheets and the complete Shiller S&P 500 dataset as direct downloads with no email registration, as research shows interest in early retirement reaching 37% of Americans.
NEW YORK — August 17, 2026 — August 2026 — firenum.com, a free retirement planning site, has published five FIRE (Financial Independence, Retire Early) planning spreadsheets and 154 years of stock market data as direct downloads on its tools page. No email address and no account are required. The release arrives as early retirement planning moves into the mainstream: Empower research shows interest in FIRE rose from 24% to 37% of Americans in two years.
The trend runs across sources. Goldman Sachs Asset Management found 30% of Americans plan to retire before age 55. Credit Karma reports 27% of Americans are actively pursuing FIRE strategies and more than half of Gen Z consider themselves part of the movement. Empower’s generational data shows expected retirement ages falling, with Gen Z targeting age 54. Most people who test an early retirement plan start in a spreadsheet.
The centerpiece download is a five-tab planning workbook covering inputs, a FIRE number calculator, a Coast FIRE calculator, a 40-year projection and a dashboard. A user enters age, spending and savings, and the projection shows the year work becomes optional. A 30-year-old spending $40,000 a year sees a Coast FIRE figure of roughly $467,000, the amount that, invested today, grows to cover retirement at age 50 with no further contributions.
Four companion sheets handle progress tracking, Coast FIRE planning, budgeting and savings rate. All five files work in Excel, Google Sheets and LibreOffice. The same page offers the complete Shiller S&P 500 dataset with monthly figures since 1871, the source data behind the site’s historical backtesting, for anyone who wants to verify the assumptions themselves.
Downloadable FIRE spreadsheets are commonly offered in exchange for an email address and arrive followed by marketing messages. These downloads require no registration of any kind.
“A spreadsheet is still how most people first take control of their money. Asking for an email address before handing one over teaches nothing. The math belongs to everyone,” said the team behind firenum.com.
The spreadsheets suit planners who prefer their numbers in a file they own. For deeper analysis, the same site runs a browser-based planner with Monte Carlo simulation, historical backtesting and stress testing at no cost. The downloads are available at firenum.com/tools.
