Miser is a Python library that can be used for writing scripts that'll help you project costs and figure out how to accumulate money. It's in unstable alpha.
Here's a simple usage:
from miser import *
from miser.scheduling import *
from miser.views import *
import random
m = Miser("test",
initialBalance = 3e3)
g = Goal(name = "bankity bank bank",
amount = 20e3, # $16,000
by = Date(2012, 9, 1)) # by Aug. 1, 2012
m.addGoal(g)
m.addTransactions(
# Expenses
Expense(name = "MATH322 tuition",
amount = 1.3e3,
on = Date(2012, 5, 29)),
Expense(name = "netflix",
amount = 7.,
on = MonthlyRecurring(15)), # 15th day of the month
Expense(name = "lunch",
amount = 6.,
on = DailyRecurring()),
Expense(name = "dinner",
amount = 5.,
on = WeeklyRecurring((SA, SU, TU, WE, FR))),
Expense(name = "breakfast",
amount = 3.,
on = DailyRecurring()),
Expense(name = "rent+utils",
amount = 800.,
on = MonthlyRecurring(29)),
# Income
Income(name = "job",
amount = 2e3,
on = MonthlyRecurring((7, 22))),
)
def unforeseen():
"""Return a random value in some range to simulate unforeseen expenses."""
return random.gauss(300., 100.)
m.addTransaction(
Expense(name = "unforeseen",
amount = unforeseen,
on = MonthlyRecurring(1))
)
def investment(principal, interest):
"""A generator that simulates an investment and interest on it, compounded
monthly."""
while True:
principal *= (1 + interest)
yield principal
m.addTransaction(
Income(name = "Investment",
amount = investment(1000, 0.07),
on = MonthlyRecurring(1))
)
