This doesn’t ask about your shopping list. It asks about your kitchen counters.

Every “homemade vs store-bought” breakdown online works the same way: someone lists five products, attaches national average prices, and declares a winner. You’re left mentally substituting your own brands and wondering if their math survives contact with your actual home. This tool skips the fake receipt. You tick the surfaces you actually clean — glass, floors, the toilet — and feed it the number you already know: what you pay for that specific bottle right now. The savings that appear on screen are built from your own habits, not a blogger’s estimate of “typical” spending.

That little slider under each task isn’t decoration.

Every homemade cleaner tutorial omits the unglamorous minutes — measuring, funneling, rinsing dried residue out of the spray nozzle. Those minutes are where the financial argument usually collapses, because time isn’t free and sliders don’t lie. The prep-time slider is your admission that a “five-minute task” on Pinterest might be twelve minutes in your kitchen the first time, or three minutes once you’ve memorized the recipe. Moving it recalculates everything downstream. Leave it high if you’re honest about the mess; drop it low if you’ve turned mixing into a smooth Sunday routine. Either way, the number belongs to you, not to us.

The DIY Pay Rate is the engine no other cleaning calculator has.

Once you’ve told us what you spend and how long it takes to mix, the tool does something beyond simple subtraction. It takes the dollars you’d save each month and divides them by the hours you’d spend mixing. That quotient is your DIY Pay Rate — the wage your mixing time is silently paying you. For most people running two or three tasks with realistic numbers, this figure lands somewhere surprising, often between $60 and $110 an hour. The ingredients cost pennies, the mixing takes minutes, and suddenly the question stops being “is DIY cheaper?” and becomes “does my real job pay me more per hour than my spray bottle does?”

The “Time as Ritual” toggle isn’t a cop-out. It’s a second calculator.

There’s a genuine philosophical split in how people value a spare fifteen minutes on a Saturday. “Strict Accounting” mode treats your time like a lawyer’s billable hour: if you could be earning your stated rate, any minute spent mixing is a minute bought back at a cost. That’s the cold, correct math. The “Time as Ritual” toggle acknowledges a different truth — that some people mix cleaning spray while listening to a podcast and don’t consider it lost income, just a slightly productive form of relaxation. Flipping between them doesn’t change the savings; it changes the story the numbers tell. The verdict line rewrites itself instantly when you flip it — no page reload, no waiting, just a different sentence for a different version of you.

The make-or-buy list doesn’t give you one answer. It ranks each product like a ruthless investor.

A single verdict of “yes, switch to DIY” or “no, don’t bother” ignores how real households work. You might happily mix glass cleaner every month because it costs nothing and works perfectly, but draw the line at grating soap for an hour to make laundry detergent. The personalized list below the main results treats every product as its own business unit, calculates each one’s individual pay rate, and ranks them from highest to lowest — the top one flagged as your Best Swap, the bottom one flagged as the one to skip. If your glass cleaner pays $95 an hour but your laundry batch pays $12 an hour against your own rate of $45, the list won’t average them — it’ll mark glass cleaner as “Make” and laundry as “Buy.” That’s a real, usable plan, not a slogan.

We didn’t bury the starter cost. It has its own line, with its own payoff date.

Spray bottles, a funnel, a glass measuring cup — these cost real money upfront. Most DIY comparisons pretend they don’t exist so the savings number looks bigger. This tool does the opposite: it adds a one-time starter kit cost based on what you picked (liquid sprays get one kit, laundry powder gets a jar), then calculates exactly how many months it takes to earn that hardware back. No buried costs, no inflated first-year projections.

Every number above comes from standard homemade cleaner recipes and typical U.S. retail prices — not your specific store, not your specific brand. Swap in your own prices where they differ, and treat the result as your personal direction, not a bank statement.
