Everyday money and work
Six free calculators for everyday household bills, memberships, tool rentals, commute trade-offs, and time-saving work decisions.
Which calculator should I start with?
Pick the tool that matches the bill, offer, or time trade-off in front of you. If you are weighing a new job or a return-to-office schedule that adds driving and parking, start with Job Offer vs. Commute Cost. A higher salary can easily turn into a pay cut once you subtract taxes, extra miles on your car, tolls, and the hours you spend on the road each week.
For household bills and recurring fees, three calculators check whether upfront or shared setups really save money. If you split electric, gas, or water bills in a duplex, rental, or shared house, use Split a Shared Utility Bill to compare square-footage, occupant, and bedroom splits, and check whether installing a submeter pays back. Before locking into a 12-month software or streaming plan, check Annual vs. Monthly Subscription to see the break-even month if you might cancel early. And before renewing Costco, Sam's Club, or Prime, run Does a Warehouse or Perk Membership Pay? to test whether gas, rewards, and grocery savings beat the yearly fee.
When a project needs a specialized tool like a pressure washer, trencher, or floor sander, open Rent vs. Buy Equipment or Tools to see how many uses it takes before buying beats renting after upkeep and resale. And if you are thinking about building a script or buying software to replace a repetitive work task, run Does Automating This Task Pay? to find your break-even month.
