You already live in Obsidian. Your notes, projects and reading lists are plain files on your own disk. Your money, meanwhile, is scattered across three apps that want your bank login and one spreadsheet that quietly broke in March and was never quite trusted again.
This post is about an Obsidian personal finance setup that does the opposite: a folder of Markdown files, no plugins, no accounts, and no connection to your bank. It is called FinVault, and I will be upfront about what it is, what it is not, and who should skip it.
It is a bookkeeping structure, not financial advice, and not software.
The empty lane: Obsidian personal finance in 2026
On 2026-10-25 I searched Gumroad with four query shapes: "obsidian finance", "obsidian budget", "budget tracker obsidian" and "obsidian net worth". All four returned zero direct paid competitors. The closest things were a $199.99 generalist starter kit and some life-OS products that touch money only in passing.
People do look for this, though. Google autocomplete completes "obsidian budget" ten times out of ten, with suggestions like budget tracker, budget template, budget planner and monthly budget template. "Obsidian personal finance" and "obsidian finance tracker" also complete with tracker and template intent.
So searchers are asking for an Obsidian budget template, and the paid supply is thin.
What the Notion side tells us (and what it doesn't)
On the Notion side, buyers clearly pay for this kind of artifact. Rated finance trackers sell at $5 (75 reviews), $9.99 (6 reviews), $29 (32 reviews) and $39 (134 reviews).
That shows adjacent willingness to pay. It does not prove demand on the Obsidian side. That part is unproven, and I would rather say so than pretend the market is settled.
Why apps and cloud templates don't hold this data well
Money data is among the most sensitive material you keep. Where it lives matters, so here is a plain comparison with no villains in it.
- Aggregator apps usually ask for your bank login or a bank connection. That buys automation, and the trade-off is that a third party sits between you and your accounts.
- Cloud workspaces such as Notion are convenient, but your transactions live on someone else's server.
- Plain Markdown files stay on your device. You can back them up however you like, search them with any tool, and grep them from a terminal.
None of these is wrong. They optimise for different things. If you care most about keeping the data local and readable in ten years, plain text has a real advantage.
The two rules that keep any budget honest
These apply to any budget, whether it is a spreadsheet, a ledger or a folder of notes. You do not need the kit to use them.
Rule 1: Never enter signed amounts
Most budget spreadsheets go quietly wrong because amounts are entered signed, and inconsistently. One month a refund is negative, the next month it is positive, and a credit card balance flips the logic again.
The fix is that amounts are always unsigned. A Type column, together with the account type (asset or liability), decides the direction. Paying down a liability and spending from an asset are then different, explicit cases instead of a guess about the minus sign.
Rule 2: Reconcile to a variance of exactly 0.00
At month end, every account balance must recompute from the transaction log. The variance should be exactly 0.00.
If it is not zero, the log is wrong. Find the error now, while it is one month old, before it compounds into a figure you stop trusting.
That habit is the reason the worked example later in this post reconciles to the cent.
What FinVault actually is
FinVault is a set of 19 files: 18 Markdown documents plus one sample CSV. You copy them into Obsidian, or into any Markdown folder. It needs zero plugins, zero accounts and makes zero network calls. Nothing leaves your device.
Disclosure: this post contains affiliate links, and the kit was created by our agency.
Product page: FinVault — The Obsidian Personal-Finance Tracker Vault.
The 19 files (13,630 words of Markdown in total) break down like this:
- 9 fill-in templates
- 1 sample CSV
- 1 formula reference
- a 3-file finished worked example
- 1 import guide
- 1 optional bonus file
- a README, a 10-minute onboarding page and a disclaimer
Feature overview
| Piece | What it gives you |
|---|
| Transaction log | Seven columns: Date, Description, Account, Transfer To, Category, Type, Amount. It has a closed category vocabulary and explicit asset-vs-liability sign rules. |
| Budget | A 50/30/20 budget with pillar mapping, plus category envelopes with a rollover rule. |
| Planning | A sinking funds tracker, a bill calendar and a financial goals page. |
| Net worth | A net-worth tracker you update at month end. |
| Review | A 15-minute monthly review checklist. |
| Formulas | formulas-and-rolls.md has 14 rollups, each printed three ways: a plain formula, calculator arithmetic, and a Sheets/Excel equivalent. |
| Import | A bank-CSV import guide and a sample CSV whose round trip was verified. |
| Optional bonus | Six Dataview queries, clearly marked optional. |
The vault works in stock Obsidian, in any Markdown editor, or even as plain text. Dataview is a bonus, never a requirement.
The worked example is the product
A blank template is easy to ship. A finished example that actually adds up is harder, and it is the part that teaches you how to use the rest.
The kit includes a complete fictional household, "Morgan Ashford", covering January to March 2026. Everything below is FICTIONAL SAMPLE DATA.
- The example has 73 transactions (FICTIONAL SAMPLE DATA).
- Monthly expense totals are 2,549.00, 2,541.00 and 2,532.00 (FICTIONAL SAMPLE DATA).
- Monthly income is 4,000.00, 4,000.00 and 4,250.00 (FICTIONAL SAMPLE DATA).
- Net worth runs 3,300.00, then 4,751.00, then 6,210.00, then 7,928.00 across the four month-ends (FICTIONAL SAMPLE DATA).
- Sinking-fund contributions sum exactly to the 1,800.00 growth in the savings account (FICTIONAL SAMPLE DATA).
Every rollup reconciles to the cent. These numbers describe a made-up household, show how the structure behaves, and say nothing about results you should expect.
You can open the example, follow a rollup by hand, and see the 0.00 variance rule at work before you enter a single real transaction.
Who it's NOT for
I would rather you skip it than buy the wrong thing.
- Anyone who wants automation. Actual Budget, Firefly III and Ledger/Beancount are free, and they do more automation than a folder of Markdown can. They are excellent tools. If bank syncing or double-entry tooling is what you need, start with them.
- Anyone looking for financial or investment advice. This is not financial advice. It is bookkeeping structure only, and the product's own README and disclaimer say the same.
- Anyone expecting software. The arithmetic is done by you, a calculator, or a spreadsheet of your own. The vault never connects to a bank.
- Anyone happy with their bank's app. If it already shows you what you need, you have no reason to switch.
FinVault sells curation, plain-file discipline and a reconciled worked example. It does not out-feature free software, and it does not claim to.
Get the kit
FinVault is listed at a $1 intro price at the time of writing. I confirmed that on 2026-10-25 against the live page. It is an intro price with a price ladder behind it, so it may rise, and I cannot promise it stays at $1.
Get FinVault on Gumroad.
It gives you structure for recording and reviewing your own money, and that is all it gives you. It makes no promises about savings or any other financial outcome.
Wrapping up
If you want an Obsidian budget that stays on your device, uses plain files and checks itself against a 0.00 variance each month, FinVault is built for that. The product page is here: the FinVault product page.
