An overall index comparison and a personal spending budget answer different questions; use explicit costs, dates and exclusions to understand the difference.

Two models answer different questions

The quick comparison asks which gross income produces the same result under an entered overall index ratio. It multiplies primary income by the destination index divided by the current index. Partner income is converted separately before a combined figure is shown. Income taxes are excluded, so the result is neither take-home pay nor a measured spending requirement. At unchanged income, purchasing power uses the reciprocal ratio; a cost decrease and the corresponding purchasing-power increase therefore have different percentages.

The personal budget instead adds category costs. Enter monthly or annual current spending, then use target quotes or a stated category index ratio. For example, assumed monthly housing and food costs of 1000 and 500 USD total 18000 USD annually. Target assumptions of 1200 and 550 total 21000 USD, a 3000 USD annual increase. These figures illustrate the arithmetic, not local prices. Changing housing alone must leave the other category costs unchanged. A household description or tenure label records context without secretly changing the calculation. Compare the same household and coverage before interpreting either result.

Missing costs, shares and housing assumptions

Entered costs and income shares are separate ways to construct the personal basket. Monthly entries are multiplied by 12 once. A manually entered target cost replaces its category projection; a housing override replaces only housing. An index projection needs positive current and target category indices, plus the disclosed target factor. The overall quick index is not silently substituted for missing category data. Enabled unknown costs keep the basket incomplete, while a typed zero is a real assumption. Disabled rows are listed as exclusions, not represented as measured zero costs.

The income-share illustration allocates primary gross income across housing, food, transport, healthcare and Other. Shares totaling more than 100% are normalized by their exact relative weights without rewriting the fields or rounding them to whole percentages. Entries 31,30,30 and 30 therefore use fractions 31/121 and 30/121, with Other equal to zero. This avoids a negative residual category, but does not turn gross income into an observed expenditure survey. Review every category, source note, annual amount and applied factor in the receipt before comparing destinations.

Sources, destinations and private receipts

The optional fifty-city reference preserves inherited vectors carrying a 2024 label. Their actual observation date, provider, locality boundaries and licence have not been established. Existing background links do not establish the origin of those vectors. The six reference-goods prices and moving ranges are also unverified illustrations. Use manual costs or provider quotes when those better describe the locations being compared, and record their geography, source dates and coverage. A source field records your assumption rather than verifying a market dataset or granting a licence.

Destination scenarios retain the same current basket, household and common comparison date. An unavailable destination does not replace another valid result. Moving-cost cash planning divides an entered moving cost by a positive modeled monthly spending reduction; a gross-income index difference is not cash savings. Edits stay on the page until explicitly saved or included in a reviewed link. Clean links contain no entered financial values. Copy and Print provide readable amounts and assumptions, while CSV preserves raw calculation values. Separately rounded rows can differ slightly from a rounded total, so use the raw receipt when reconciling the arithmetic.
