Compare a bare drill with a complete kit
Build a like-for-like list of the tool, compatible battery, charger, accessories and delivery. A body-only headline is not the cost of a usable purchase.

Two genuine UniversalDrill bundles before any arithmetic
Compare the cost of a complete, documented selection rather than a bare drill headline against a ready-to-use kit. Body-only, bare, kit and bundle are descriptions to investigate, not standardised contents lists. Two offers carrying the same tool family name can have different batteries, chargers, cases and accessories.
For a real UK manufacturer example, Bosch lists UniversalDrill 18V-60 order 06039D7000 without battery or charger, while order 06039D7070 lists a PBA18V2.0Ah battery, AL18V-20 charger and case. These are checked delivery descriptions, not current price or stock claims.
Save the full order code and list every included component. Mark whether each item is supplied, already owned and documented compatible, or still needed. An absent battery price is not zero cost unless an existing suitable battery really covers the requirement. A seller photograph of a case full of equipment is not a substitute for the written delivery list.
Bosch UK order06039D7000 is the UniversalDrill18V-60 without battery or charger, supplied with a double screwdriver bit and cardboard box. The same product page lists order06039D7070 with one PBA18V2.0Ah battery, an AL18V-20 charger, double bit and carrying case. The motor model does not make those packages equivalent.
The bare tool is a plausible shortlist only when compatible owned power equipment is confirmed or its additional cost is included. The kit addresses a missing battery and charger with named components, but one supplied pack is not a promise of uninterrupted work. Compare dated authorised seller offers for these exact order numbers and contents. No current price or availability is asserted here; the arithmetic below remains a labelled hypothetical example.
| Bosch UK order | Battery/charger | Packaging |
|---|---|---|
| 06039D7000 | Neither supplied | Double bit;cardboard box |
| 06039D7070 | 1×PBA18V2.0Ah;AL18V-20 charger | Double bit;carrying case |

Use a transparent example with your own amounts
For an expressly hypothetical comparison, assume a body costs £110, a compatible battery allowance is £45, a charger allowance is £30, required accessories are £20 and delivery is £5. The complete stated allowance is £210. These are invented planning inputs, not observed prices or an offer for the equipment in the photographs.
If another complete offer is quoted at £195 with the same documented scope, the difference is £15. If that offer omits a required £30 charger, its adjusted comparison becomes £225 instead. Keep the original quotation and the adjustment visible; do not silently change the basket and call the result a discount.

Treat owned components as a compatibility question
An existing pack can reduce the new purchase allowance only after its exact identifier is checked against the proposed tool and suitable charger. Brand, colour, nominal voltage and a similar sliding shape are not a compatibility table. The Bosch battery advisor is an example of a manufacturer source that ties battery recommendations to particular tool families.
Keep the identifier and relevant document with the cost sheet. Do not assign a saving for an unofficial adapter or assume that a pack from a professional range fits a different DIY system. The photographs show component types; they do not establish that any pictured battery and tool can be combined.

Make exclusions visible before comparing totals
A useful list separates the power tool from accessory items needed for the intended task and from optional convenience purchases. Duplicate chargers, a larger case or a spare battery may be valuable in some households and unnecessary in others. Record that choice instead of pretending every bundle has the same usefulness.
Check the quoted delivery scope, the seller, the included quantity and any returns conditions directly before purchase. We have no authorised live stock or price feed and do not publish current retailer prices. A calculation can add stated amounts accurately while still describing the wrong or incomplete purchase.

Keep the offer and the calculation together
Use the complete-kit calculator to add the amounts you have chosen, then save a dated comparison alongside the seller’s written contents and manufacturer compatibility evidence. Inputs remain in your browser. Editing an input clears the displayed result so a previous total cannot masquerade as the calculation for a new basket.
Choose the offer that resolves the intended task at an acceptable documented total, not automatically the smallest headline. If one required component is still uncertain, mark the comparison provisional and obtain an answer before committing. This cost worksheet does not approve safe operation, an accessory connection or an electrical charging arrangement.
