nc_break_even_yrs: Calculate number of years it takes to break even (if ever)

Description Usage Arguments See Also Examples

View source: R/nc-results.R

Description

Generally it will take some number of years for cumulative revenue in the lifetime scenario to catch up with cumulative revenue in the annual scenario. If the lifetime scenario does catch up, the years to break even represents the number of years it takes for this to happen. Only rows (ages) where the current price is above the break-even price will be returned (otherwise to lifetime return will never reach the annual return scenario).

nc_break_even_yrs(retain_all, prices, return_life, inflation,
  wsfr_amount = NULL, min_amount = NULL, senior_price = NULL,
  youth_ages = 0:15, age_cutoff = 80, fund_years = 0:200,
  senior_age = 65)

Arguments

retain_all

data frame of predicted years by age like that produced by nc_retain_all

prices

data frame of lifetime prices by age with at least 2 variables: current_age and price_lifetime

return_life

percentage return from lifetime fund

inflation

inflation rate for depreciation of lifetime fund

wsfr_amount

numeric estimated amount for aid dollars (use SFRF for fishing, WRF for hunting)

min_amount

numeric the minimum expenditure that will count for a certified hunter/angler (use 2 for hunt/fish and 4 for combo)

senior_price

numeric price for a senior lifetime license

youth_ages

if not NULL, assumes for youths that the fund is able to compound until adulthood (when the agency will begin drawing revenue). See nc_price_lifetime_youth for details.

fund_years

range of years to cast forward for stream-based lifetime fund valuation
