GUIDE

FINA in five minutes.

One book for one year. Three views. One goal: know what’s coming.

What FINA is

FINA keeps one household year: everything that comes in and everything that goes out, January through December. Three kinds of money keep the book tidy: income (salary, side jobs), regular costs (rent, subscriptions, insurance, loans) and flexible spending — everyday money, one amount per month and category, like “household” or “leisure”.

Everything lives in a single file that stays on your computer. No account, no cloud, no bank connection.

The year view: build your year here

Twelve months side by side, one row per item. This is where you set things up: enter the rent once and it sits in all twelve months. Settled months get struck through, the current one is framed in red.

The LP column is the traffic light: it shows how many payments a subscription, contract or loan still costs. Green means: ends this month. Blue: two to three months. Yellow: four to six. Red: seven or more. One glance tells you when you’ll breathe easier.

The month view: this is where you work

One month, three cards: income, flexible spending, regular costs. When something is paid, you tick it off — one click on the seal. Every number tells you how firm it is:

Ticked means: that’s what really happened. Open means: still due. Orange means: estimated — the number is an assumption, not a fact. That’s why FINA asks for the real number before you can tick off an estimate.

The month view with its seals — and the analysis opened above it: the timeline shows how the month moves your account, start, middle, end. By default the analysis is collapsed; one click on its row opens it whenever you want the overview.

The forecast: your balance through December

Every row is a month and reads like a bank statement: what it starts with, what moves it, what it closes with. Next to it, the track draws your balance across the year — you see a gap months before it arrives, and just as clearly how much room an expiring loan gives you.

Your file, your rules

Your whole year lives in one file, and it lives wherever you want: on your desktop, in your own cloud folder, on a stick. It is only saved when you press save. FINA uploads nothing and needs no internet — browser, Mac app and Windows app open the very same file.

The screenshots show the English interface — German is built in, switchable in the settings.

How to start

  1. Open it in the browser. Nothing to install, nothing to sign up for. Choose “Start from scratch”.
  2. Enter income and costs. Rent, salary, subscriptions — plus a monthly amount for everyday spending. Once, for the whole year.
  3. Tick things off month by month. What’s paid gets its tick — and estimates turn into real numbers.
  4. Check the forecast. It shows where your account lands in December.

More help lives inside the app: the guide button at the top right explains every view, step by step.
