networth 0.3.0

Getting Started

You download and install Networth with:

pip3 install --user networth

Once installed, you will need at least two configuration files. The configuration files are Python code. The first file contains settings that are shared between all profiles. It is ~/.config/networth/config. The remaining files are specific to profiles. You would generally have one profile for yourself, but you might also have profiles for organizations or people that you are monitoring.

In general, any setting may be in either the config file or the profile file. However, the following two settings should in the config file:

default_profile

A string that contains the name of the profile to use if the one is not explicitly specified on the command line. The name specified in this setting must also be one of the names specified in profile_names.

profile_names

A list the contains the names of the known profiles. For every name given there should be a profile file in the settings directory. Thus, if me is one of the profile names, then there should be a file ~/.config/networth/me.prof that contains the settings associated to the me profile.

In addition, the following settings are available:

avendesora_fieldname

The name of the Avendesora account field that contains the networth information.

value_updated_subfieldname

The name of the subfield of estimated_value that contains the date the value was last updated. Typically updated.

max_account_value_age

Number of days. Values that are older than this are called out as being stale.

date_formats

A string that contains the allowed date formats separated by white space. Any spaces is a specific format is replaced by an underscore so that it is not confused as more than one format. For example a format of ‘MMMM YYYY’ would be represented as ‘MMMM_YYYY’. The formats allowed are those supported by Arrow.

May also be a list of strings, where each represents a valid date format.

By default the following formats are accepted: ‘MMMM YYYY’, ‘MMM YYYY’, ‘YYYY-M-D’, and ‘YYMMDD’. So the following dates would be accepted: ‘January 2019’, ‘Jan 2019’, ‘2019-1-1’ and ‘190101’.

asset_color

The color to used for positive values. May be black, white, blue, cyan, green, red, magenta, or yellow. The default is green.

debt_color

The color to used for negative values. May be black, white, blue, cyan, green, red, magenta, or yellow. The default is red.

screen_width

An integer that contains the width of the screen.

aliases

A dictionary that is used to map an account name to something that is easier to read.

coins

A list of crytpocurrency tokens that should be available for use.

coin_prices_filename

Name of the file used as the cryptocurrency price cache.

securities

A list of security symbols that should be available for use.

security_prices_filename

Name of the file used as the security price cache.

max_price_age

Maximum age in seconds of the price caches. If the prices are older than this, the cache is flushed and the prices are updated.

Example Configuration Files

Here is an example config file:

default_profile='me'
profile_names = 'me parents'.split()

# account value settings
avendesora_fieldname = 'estimated_value'
value_updated_subfieldname = 'updated'
max_account_value_age = 120 # days
date_formats = 'MMMM YYYY'

# bar settings
screen_width = 110

Here is a example profile file:

# account aliases
aliases = dict(
    quickenloans = 'mortgage',
    wellsfargo = 'wells fargo',
)

# available symbols
coins = 'USD BTC ETH BCH ZEC EOS'.split()
securities = 'GOOG AMZN'.split()

Estimated Values

Next, you need to add estimated_value fields to your Avendesora accounts, the value of which is a dictionary. It may contain a updated subfield that gives the date the value was last updated. In addition, it may contain subfields for various asset classes or coins or securities. The values may either be real numbers or strings that contain quantities (values plus units). Here are some examples:

class ChaseBank(Account):
    ...
    estimated_value = dict(updated='December 2018', cash=2181.16+5121.79)

class QuickenLoans(Account):
    ...
    estimated_value = dict(updated='October 2018', real_estate='-$294,058')

class Vanguard(Account):
    ...
    estimated_value = dict(updated='November 2018', retirement='$74,327')

class UnitedAirlines(Account):
    ...
    estimated_value = dict(updated='July 2018', miles='7,384_miles')

class Kraken(Account):
    ...
    estimated_value = dict(updated='August 2018', ETH=2, BTC=4, cash=24.52)

class TD_Ameritrade(Account):
    ...
    estimated_value = dict(updated='January 2019', GOOG=10, AMZN=5, cash=327.53)

The value of securities are given is number of shares. The value given for cryptocurrencies is number of tokens. All other values are assumed to be in dollars if the units are not given. If the units are given and they are not dollars (such as miles for frequent flier programs), then those values are summarized but not included in your total networth.

Specifying the updated date is optional. If specified, then networth will indicate the values as stale if they exceed max_account_value_age.

It is also specify information about a loan, and networth will compute its current balance. This is done by giving the principal on a particular date, the date for the given principal, the monthly payments, the interest rate, and optionally, the share. The rate and the share can be given in percent, meaning that an rate of 4% can either be specified as 4% or as 0.04. Similarly a share half share can be indicated as 50% or 0.5. For example:

class QuickenLoans(Account):
    ...
    estimated_value = dict(
        real_estate = '''
            principal=-$294,058
            date=09/04/2013
            payment=$1,500.00
            rate=4.375%
            share=50%
        '''
    )

the key=value pairs can be separated by any white space, but there must be no white space surrounding the = sign. For mortgages that you owe, the principal should be negative. You can also use this feature to describe an automatic savings plan into an interest bearing account. In this case the principal would be your starting balance and the payment would be your monthly investment amount. In this case the starting balance would be positive.

Usage

When running the command, you may specify a profile. If you do not, you get the default profile. For example:

> networth me
By Account:
        betterment:    $22k equities=$9k, cash=$3k, retirement=$9k
             chase:     $7k cash
         southwest:      $0 miles=78kmiles
          coindesk:  $15.3k cryptocurrency

By Type:
    cryptocurrency:  $15.3k (35.3%) ██████████████████████████████████████████
              cash:    $10k (23.1%) ███████████████████████████████
          equities:     $9k (20.8%) ███████████████████████████
        retirement:     $9k (20.8%) ███████████████████████████

             TOTAL:  $43.3k (assets = $43.3k, debt = $0)

In this run, the values associated with the various asset classes (ex. equities, cash, retirement, etc.) are taken as is. As such, you must be diligent about keeping these values up to date, which is a manual operation. You might consider updating your estimated values every 3-6 months. However the current prices for your configured securities and cryptocurrencies are downloaded and multiplied by the given number of shares or tokens to get the up-to-date values of your equities and cryptocurrency holdings. Thus you only need update them after a transaction. Finally, mortgage balances are also kept up to date. You only need update mortgages if you decide to change the payment amount in order to pay off the loan faster.
