- computes interest for a given account
- Description
hledger-interest is a small command-line utility based on Simon Michael's hleder library. Its purpose is to compute interest for a given ledger account. Using command line flags, the program can be configured to use various schemes for day-counting, such as act/act, 30/360, 30E/360, and 30/360isda. Furthermore, it supports a (small) number of interest schemes, i.e. annual interest with a fixed rate and the scheme mandated by the German BGB288 (Basiszins fuer Verbrauchergeschaefte). Extending support for other schemes is fairly easy, but currently requires changes to the source code.
As an example, consider the following loan, stored in a file called
test.ledger:2008/09/26 Loan Assets:Bank EUR 10000.00 Liabilities:Bank 2008/11/27 Payment Assets:Bank EUR -3771.12 Liabilities:Bank 2009/05/03 Payment Assets:Bank EUR -1200.00 Liabilities:Bank 2010/12/10 Payment Assets:Bank EUR -3700.00 Liabilities:BankSuppose that loan earns 5% interest per year, and payments amortize interest before amortizing the principal claim, then the resulting ledger would look like this:
$ hledger-interest --file=test.ledger --source=Expenses:Interest --target=Liabilities:Bank --30-360 --annual=0.05 Liabilities:Bank 2008/09/26 Loan Assets:Bank EUR 10000.00 Liabilities:Bank 2008/11/27 Payment Assets:Bank EUR -3771.12 Liabilities:Bank 2008/11/27 5.00% interest for EUR -10000.00 over 61 days Liabilities:Bank EUR -84.72 Expenses:Interest 2008/12/31 5.00% interest for EUR -6313.60 over 34 days Liabilities:Bank EUR -29.81 Expenses:Interest 2009/05/03 Payment Assets:Bank EUR -1200.00 Liabilities:Bank 2009/05/03 5.00% interest for EUR -6343.42 over 123 days Liabilities:Bank EUR -108.37 Expenses:Interest 2009/12/31 5.00% interest for EUR -5251.78 over 238 days Liabilities:Bank EUR -173.60 Expenses:Interest 2010/12/10 Payment Assets:Bank EUR -3700.00 Liabilities:Bank 2010/12/10 5.00% interest for EUR -5425.38 over 340 days Liabilities:Bank EUR -256.20 Expenses:Interest 2010/12/31 5.00% interest for EUR -1981.58 over 21 days Liabilities:Bank EUR -5.78 Expenses:InterestRunning the utility with
