A useful financial independence check-in needs a record of today and a way to explore tomorrow. Start with a cash-flow workbook and a net-worth snapshot, then add a projection tool for the question you are trying to answer. These six resources have public tools or free downloads; they do not all provide account syncing or replace a complete financial plan.
What “free” means in this list
We reviewed public pages and download descriptions on October 21, 2026. The specific resources below are available without a paid planning subscription; optional services and the software used to open a file may cost money. FireFolio publishes this list and includes its own tools. Links go directly to the providers, without affiliate tracking. This is a curated resource guide, not a security audit or a test of every spreadsheet formula.
| Resource | Best use in a FIRE check-in | Format / boundary |
|---|---|---|
| FireFolio toolkit | Forecast cash and review the monthly budget | Browser tools and downloads; local drafts do not sync to an account. |
| FireFolio net-worth calculator | Record assets minus debts | Manual snapshot; a total is not a spendable retirement balance. |
| Vertex42 retirement savings workbook | Explore accumulation in a spreadsheet | Excel download for personal use; not a full household plan. |
| CFPB Your Money, Your Goals | Organize bills, cash flow, and debt | Downloadable handouts; not an investment forecast. |
| Investor.gov compound calculator | Check basic savings arithmetic | Public browser calculator; not a retirement withdrawal test. |
| FI Calc | Explore retirement spending against history | Public simulator; not a live account tracker. |
1. FireFolio’s financial wellbeing toolkit
The toolkit combines a twelve-month cash forecast, monthly check-in, net-worth snapshots, and debt comparison with downloadable planning resources. Use it when annual averages hide a difficult month. Enter actual bills and the month they are due, then look at the lowest projected cash balance as well as the year-end result.
No account is required for the public toolkit. Saving on this device uses browser storage; a backup or workbook lets you keep a separate copy. A local draft does not automatically sync with your FireFolio account. The forecast does not assume investment growth.
2. FireFolio’s net-worth calculator
Use the net-worth calculator for a simple inventory of assets and liabilities. Record values on a consistent date so a change in timing does not masquerade as progress. Keep notes about valuations that are estimates rather than current account balances.
For FIRE, track investable assets beside total net worth. Home equity can matter enormously to your life without being available for withdrawals. Do not count a property’s full value and its equity as two separate assets, or subtract the same debt twice.
3. Vertex42’s retirement savings spreadsheet
Vertex42 offers a downloadable Excel workbook for exploring retirement savings from a starting balance, contributions, and assumed returns. It is a useful fit if you prefer a file you can inspect and revisit. The publisher licenses it for personal use, not redistribution or resale; download it from the original page.
Keep an untouched copy before editing formulas, and check any compatibility issues in your chosen spreadsheet application. Accumulation arithmetic does not by itself answer account access, taxes, or sustainable retirement withdrawals.

4. CFPB’s Your Money, Your Goals toolkit
The CFPB provides free handouts for bills, income, cash flow, goals, and debt. Choose it if you want a printable structure for a household conversation or need to get the basic records in order before running long-term projections.
Use the cash-flow and debt materials alongside your own statements. These worksheets organize information; they do not forecast market returns. Check the edition date and use current official sources for any rules or benefits that have changed.

5. Investor.gov’s compound interest calculator
The SEC’s public calculator is a straightforward way to explore an initial investment, recurring contributions, a time horizon, and assumed interest rates. Use it as a basic arithmetic check when a complicated spreadsheet’s result seems surprising.
Match contribution timing and compounding assumptions before expecting two tools to agree. The result follows the rates you enter; it does not establish what markets will return or how long withdrawals will last.

6. FI Calc for a retirement-phase check
FI Calc adds historical withdrawal analysis to a routine that otherwise focuses on current balances. Try different retirement durations and spending rules, then inspect both portfolio survival and the spending delivered by the strategy.
Treat this as a scenario tool alongside your records, not as a tracker of your actual accounts. Keep a note of the configuration used so a later change in assumptions is not mistaken for a change in your finances.

Build a monthly routine with fewer moving parts
Pick one place for actual balances and spending. Update it on the same day each month, then use a separate model for future scenarios. Record contributions, investment changes, and assumption changes separately. You do not need all six tools every month; you need a record you can understand and maintain.
