Paisa supports a simple budgeting system. Let's say you get 50000 INR at the beginning of the month. You want to budget this amount and figure out how much you can spend on each category.
Let's add a salary transaction to the ledger:
Now you have 50k in your checking account. Let's budget this amount:
~ character indicates that this is a periodic transaction. This
is not a real transaction, but used only for forecasting purposes. You
can read more about periodic expressions and periodic transactions.
Even though the interval part is optional as per the doc, there is a
bug in the ledger-cli, so you can't use
~ in 2023/08/01,
instead you always have to specify some interval like
~ Monthly in 2023/08/01.
Now you can see that you will have 5k left in your checking account at the end of the month, if you spend as per your budget. Before you spend, you can check your budget and verify if you have money available under that category.
Let's add some real transactions.
Expenses:Rent 15,000 INR
Expenses:Transport 1,000 INR
Expenses:Food 8,500 INR
Expenses:Transport 2,000 INR
Expenses:Transport 3,000 INR
Expenses:Personal 4,000 INR
Expenses:Insurance 10000 INR
As the month progresses, you can see how much you have spent and how much you have left. You notice that you have overspent on transport and you have missed the insurance payment. You have a budget deficit now. That means, you can't actually spend as per your budget. You have to first bring the deficit back to 0. Let's cut down the entertainment and clothing budget to 0
You can go back and adjust your budget anytime. Let's move on to the next month, assuming you haven't made any further transaction.
You can see a new element in the UI called Rollover1. This is basically the amount you have budgeted last month, but haven't spent. This will automatically rollover to the next month. That's pretty much it.
To recap, there are just two things you need to do.
1) Create a periodic transaction at the beginning of the month when you get your salary.
2) Adjust your budget as you spend and make sure there is no deficit.
