Same formula as https://profitdrawer.com/tools/startup-cost-calculator.html. Optional preset with example amcalculate_price_per_jobWorks out a price for one service job: cost = hours x hourly pay + materials + travel + monthly overhead / jobs per month; price = cost / (1 - profit margin). Also returns profit per job, monthly revenue and break-even jobs per month. Same formula as https://profitdrawer.com/toolcalculate_loan_payoffWorks out how many months a loan takes to pay off and the total interest, month by month (one month of interest = APR / 12 is added, then the payment is taken off), and what an optional extra monthly payment saves in interest and time. Same method as https://profitdrawer.com/toolcalculate_tax_set_asideEstimates how much of a self-employed profit to set aside for taxes: set-aside = profit x chosen percent, and the US self-employment tax part = profit x 92.35% x 15.3% (12.4% Social Security + 2.9% Medicare), per month, quarter or year. Same formula as https://profitdrawer.com/toLink
