Budgeting Help / The $10k Strategy resource center
Quick answer: Estimate resale proceeds minus the purchase price and all selling costs, then allow for relevant taxes and operating needs before counting money toward savings. Include your time and a lower-price outcome; a cheap purchase alone does not make a profitable deal.
Start with the selling price you can defend
A resale calculation begins with demand evidence, not with the discount a seller offers. Identify the model and compare condition, accessories and location. Completed sales are useful where available. Active listings show what people hope to receive, which can be very different from a completed transaction.
Choose a conservative expected sale price and record the evidence behind it. If your estimate depends on restoring an unfamiliar machine or finding a rare collector, acknowledge that uncertainty. A beginner test works better when the item is understandable, transportable and straightforward to describe.
Separate margin from money available
Suppose you buy a dresser for $40 and sell it for $100. The difference is $60. If collection costs $10 and supplies cost $5, $45 remains before taxes and other applicable costs. If the hypothetical seller reserves $10 for their assessed tax needs, $35 is available for the goal.
The $10 reserve is not a recommended rate. Actual obligations depend on the person’s circumstances. The point is that a $100 sale, a $60 price difference and $35 of retained money are three different numbers. A plan based on one must not silently report another.
Include costs that are easy to forget
Write down fees, transport, packaging, delivery, helpers, repairs and supplies where relevant. For shipped goods, determine packed dimensions and obtain a current shipping estimate before buying. For local collection, include the whole journey rather than just the outward drive. Consider the cost of an unsuccessful collection or a return when evaluating the downside.
Storage and operating cash also matter. If the sale recovers a $40 stake that must remain available for the next purchase, that recovered capital is not new profit. Moving the same stake through five transactions does not mean you earned it five times. Keep a separate inventory record.
Use a maximum-offer formula
Subtract estimated nonpurchase costs and your required pre-tax margin from the conservative expected sale price. If the sale estimate is $120, other costs are $25 and the required margin is $45, the maximum purchase price is $50. This example gives you a decision point before negotiating.
A seller asking $65 may have a reasonable price for someone else. It still does not fit this particular calculation. You can revise an estimate if new evidence supports it, but do not change the numbers solely because you want to buy the item. Passing is a normal part of the process.
Calculate the disappointing outcome too
Return to the $40 dresser. If it sells for $70 instead of $100, with the same $15 in direct costs, only $15 remains before a reserve. If it sells for $55, those listed cash costs are merely recovered. Your time has earned nothing in that version of the transaction.
Ask whether you can absorb a loss without affecting essentials. Set an exit date for unsold stock and a fallback decision. An item sitting in storage may have an estimated value, but it is not cash retained toward a 90-day goal. Avoid buying several similar items before one full cycle has worked.
Measure all the hours
Include researching, messaging, travel, cleaning, photographing and meeting the buyer. A $35 retained result over 2.5 hours is $14 per hour. Over five hours it is $7 per hour. Neither number predicts the next transaction, but both are more informative than remembering only the sale price.
Use the same basis when comparing a flip with paid work. Comparing a resale figure after reserves with a service job’s gross hourly rate gives a misleading answer. Also consider reliability, physical effort, payment timing and the amount of money put at risk.
Keep records for separate tax questions
The IRS gig-economy guidance explains that income can be taxable even when no information form arrives. Save receipts and transaction details. Your challenge worksheet is a planning record, not a substitute for determining deductible expenses or filing obligations. Obtain advice suited to your situation when needed.
The companion PDF includes a buy-or-pass worksheet with space for demand evidence, full costs, a maximum offer and the completed result. Use it on one small test first. Its purpose is to make an uncertain decision clearer, not to make every purchase a winning deal.
