finance-sim

A simple simulator which simulates what will happen to your bank account on a daily basis given a certain set of transactions and bank fees.

Usage

First, install finance-sim:

npm i -g finance-sim

Then, add your transactions and bank fees to config.toml. Here's an example:

[[bank-fees]]
name   = "Overdraft Fee"
entity = "Chase Bank"
amount = -34
if     = "balance < 0 && expensesMade"

[[transactions]]
name   = "My Paycheque"
entity = "ACME, Co."
amount = 2000
when   = "firstnotweekend(monthly(20))"

[[transactions]]
name   = "Rent"
entity = "My Landlord"
amount = -1500
when   = "monthly(1)"

Then run the script:

# finance-sim <starting balance> [start date] [end date]

finance-sim 3400 2017-1-1 2017-2-1

And you'll get output much like this:
