How to Budget for a PC Build: Parts, Tax and Shipping

Decide what your total has to buy

Write either “tower only” or “complete setup” at the top of the list. For a complete setup, include the monitor, keyboard, mouse, operating system and any adapters or mounting kits you need. Mark the parts you already own so you do not budget for them twice.

Keep all amounts in one currency and leave gaps visible. A missing PSU price is still a cost to find, not spare money for a faster graphics card.

Make sure the cheaper listing is the same product

Compare the full manufacturer model, capacity, revision and condition. Two cards using the same graphics chip can have different coolers, dimensions and included accessories. A used listing may also omit a cable or mounting kit you need.

If the products differ, treat them as alternatives to assess rather than counting the price difference as a saving on the same item.

Compare baskets, not just individual prices

Add delivery and checkout charges for your destination before choosing a shop. Splitting an order across three sellers can erase the saving from their lower item prices. Check the return route and warranty region as well, especially on an imported part.

Changing the website’s display currency does not make a listing local. Use the store’s delivered total for your address when deciding whether it fits the budget.

A $900 list can exceed a $1,000 budget

Here is a hypothetical tower order: $900 in components, $45 delivery and $70 in tax shown at checkout. That comes to $1,015—already $15 over a $1,000 target, with no monitor or operating system included.

Now suppose a second shop offers one of those parts for $20 less but charges another $25 to deliver it. Moving that item raises the total by $5. These are illustrative amounts, not current quotes or a tax-rate estimate.

Keep a quote sheet you can update

Beside each price, record the exact model, seller, condition, currency, destination and date. Put basket delivery and checkout charges on separate lines so you do not count them once per component.

When you swap a part or seller, recalculate the basket. A discount or free-delivery threshold may have changed. The useful number is the amount you can actually order the complete list for, with any missing quotes still called out.

Your checklist

• Choose tower-only or complete-setup scope.
• List components, peripherals, software and any needed adapters or mounting kits.
• Record exact new or used listings in one currency.
• Add delivery and the charges shown for your destination.
• Check returns, warranty region and missing prices before placing orders.
