How do resellers calculate mileage deduction value?

Multiply business miles by the mileage rate that applies to your tax year and location. Keep the rate editable because official rates and local rules can change.

What reseller trips should go in a mileage log?

Common business trips include thrift store sourcing, estate sales, garage sales, auctions, post office drops, storage visits, shipping supply runs, and local pickup trips.

Why should mileage be tied to sourcing profit?

A route can look profitable before driving costs but weak after mileage, parking, tolls, supplies, and unsold inventory are included. Trip-level tracking helps resellers repeat the routes that actually produce profit.

Formula

Mileage is not just a tax number.

Mileage deduction estimate = business miles × mileage rate.
This is an estimate only. Always confirm the rate and rules that apply to your tax year, state, country, and business setup.

Route profit = projected gross profit - mileage estimate - parking - tolls - trip supplies.
Use this to compare sourcing routes. A long run can still be worth it if it reliably produces high-margin inventory, but it should beat nearby alternatives after all costs.

How resellers use it

Decide which routes to repeat

Check the route before buying more

Estimate mileage, parking, tolls, and supplies before deciding if a sourcing loop is really better than a closer store.

Tie miles to purchase sources

Label repeat routes as purchase sources so inventory, cost, and sales can be compared by actual sourcing channel.

Review sold items, not just hauls

A route that creates a huge death pile is not better than a smaller route with faster sell-through and cleaner profit.

FAQ

Reseller mileage deduction questions

Is this calculator tax advice?

No. It is an educational estimate for reseller planning. Mileage rules and rates can change, and the right treatment depends on your location and business situation. Confirm details with a qualified tax professional.

Should resellers track mileage even before tax time?

Yes. Mileage helps you judge whether a sourcing route, storage setup, or shipping routine is profitable. Waiting until tax time means the route-level decision signal is already gone.

Can I include post office and storage trips?

Business-only shipping and storage trips are common mileage-log entries for resellers. If a trip mixes personal errands and resale work, keep the business portion clear and documented.

What should I do after using the calculator?

Save the trip as an expense or source note, attach receipts for parking or supplies, then track the items from that route through listing, sale, fees, shipping, and profit.
