guito brings your accounts, investments, assets and credits into a single view. To do that, it computes a balance for every account, values every asset, and adds it all up into your total net worth. This page explains, in plain terms, how that calculation works, so you always understand where each number comes from.
You don’t need to know any of this to use guito. This is for anyone who wants to understand what sits behind the values shown in the app.

​
An account’s balance

Every account, whether automatic, manual, or imported from a file, follows the same logic. The balance on a given day starts from a reference point and, where it applies, adds the movements that came after it. A reference point is a known balance on a specific date. There are two kinds:

Bank-reported balance

The balance your bank reports on a date, through automatic sync. It’s the bank’s word for that day.

Balance reconciliation

A balance you set by hand on a date: “at the end of this day I had exactly this much”.
The rule changes depending on where the reference point comes from.

​
Automatic accounts: the bank is the truth

When the bank reports a closing balance, that figure already accounts for every movement on that day. guito shows that value directly, without adding the movements again (otherwise they’d be counted twice). So on an automatic account, each day’s balance is the most recent balance the bank reported up to that date. Any movements you add by hand on an automatic account are kept for cash-flow tracking, but they don’t change the computed balance: the truth is what the bank reports.

​
Manual accounts: your reconciliation plus movements

On a manual account, you set a balance reconciliation, and guito adds the movements from there onward. For example:
  • On January 1, you set a reconciliation of €10,000.
  • On January 15, you record a €500 expense: the balance becomes €9,500.
  • On January 31, you record €2,000 of income: the balance becomes €11,500.
Movements recorded on the same day as the reconciliation are absorbed: the reconciliation is the balance at the end of that day. Only movements after the reconciliation date change the balance.
On a manual account, any movement you add or delete changes the balance immediately. There’s no “confirm or not” step: the account always reflects your movements.

​
Opening balance when you create an account

The “current balance” you enter when creating a manual account is a start-of-day balance: a point the balance grows from. Movements on that day and on the following days add on top of it. This is different from a later reconciliation, which represents the balance at the end of the day.

​
The role of reconciliation

A reconciliation pins an account’s balance on a date: the history anchors to that value, and from there it is rebuilt by adding the movements that came after. The amount you enter is the balance at the end of the chosen day. That makes a reconciliation useful both for correcting a history that has drifted from reality and for giving a starting point to an account that has none yet. Reconciliation is available on both manual and automatic accounts. On an automatic account, it lets you seed the history before the first synced date, avoiding a flat line at €0, or correct a value the system inferred. The step-by-step for creating a reconciliation lives in Accounts. When several reference points fall on the same date, there’s an order of priority: a balance you set by hand takes precedence over the bank’s value, which in turn takes precedence over a value computed by the system. So if you set a reconciliation on the same day the bank reported a balance, your value wins, because it’s the most deliberate correction.

​
When a bank disconnects

If a bank connection is no longer active, because it was removed, the consent expired, or the connection was suspended, the bank-reported balances can no longer be treated as current. From that moment on, the last known bank balance becomes the baseline, and any movements you add afterward adjust the balance forward, just like on a manual account. Reconnecting the account restores the normal behavior.

​
Every situation, summarized

The balance goes down with the expense and back up if you delete it. The math is always live.
The balance for every date after that movement adjusts automatically.
All balances adjust automatically, with no extra steps. Repeated movements are detected to avoid duplicates.
Each period is independent: the first runs from the first reconciliation plus its movements; the second runs from the second reconciliation.
It’s kept for cash-flow tracking, but it doesn’t change the computed balance: the bank is the truth.
The balance is simply the sum of all movements. To fix it, set a reconciliation on a past date with the known balance.

​
Investments and assets: valuation, not balance

Not everything has a bank balance. The other net-worth categories are valued:
  • Investments: each position is valued at the latest quote for the instrument. When the instrument is in a currency different from your base currency, the value is converted at the exchange rate nearest to the date. For certain index-linked products, the value is computed from the applicable reference rate instead of a market quote.
  • Assets (property, vehicles, and others): they’re worth the most recent valuation you record.
  • Credits: the outstanding amount is computed from the amortization schedule and the balance reconciliations you record.
guito does not give investment advice. It describes products and shows their values factually, without recommending, ranking, or evaluating any instrument.

​
From balance to total net worth

The Overview page (/overview) brings everything into a single view. For the date in question, guito computes each account’s balance following the rules above, values each investment and asset at the latest quote or valuation (converting to your base currency when needed), and finally adds the assets and subtracts the liabilities. The result is your total net worth: everything you own (accounts, investments, assets, cash) minus what you owe (credits). The same calculation runs day by day to draw your net worth over time. For days with no new information, the last known value is carried forward until a more recent value appears.
