Every NDIS plan is split into budgets, and the single biggest source of confusion — and wasted funding — is families assuming money can move freely between them. It can't, not evenly. One budget is flexible. Two are not. Getting this wrong is how families end up with a large "Improved Daily Living" balance sitting untouched while they're turning down Core supports because they think the plan is empty.
This guide explains what each budget actually funds, which one you can shift money around in, what happens to funding you don't spend, and how to actually check your balance instead of guessing.
Most NDIS plans are built from three main budgets. A plan may also include a separate budget for Support Coordination in some cases, but Core, Capacity Building, and Capital are the ones every participant needs to understand.

This is the part that trips families up most, so it's worth being precise about it.
Within Core Supports, funding is flexible. The NDIS states you can "use the total amount in this budget to buy NDIS supports across and within the support categories" — meaning you can shift the balance between daily activities, consumables, and community participation as your needs change through the plan, without asking permission for every reallocation.
Within Capacity Building Supports, funding is generally not flexible. The NDIS is explicit: "The funding in your capacity building support categories is a stated support. This means you can't move your funding between support categories." A category like Improved Daily Living can't be raided to top up Improved Health and Wellbeing, even if both sit under the same overall Capacity Building umbrella. There's some flexibility within a single category — therapy funding, for example, can generally cover different therapy types that address your goals — but not between categories.
Capital Supports funding is stated and tied to the specific item or modification approved in your plan. It's the least flexible of the three.
You cannot move funding between the three main budgets at all — Core money stays in Core, Capacity Building money stays in Capacity Building, Capital money stays in Capital.
"A healthy Core Supports balance and an untouched Capacity Building balance are not interchangeable. One is spare cash. The other is money with a job to do."
The most common mistake families make: treating a Capacity Building balance as if it's spendable like Core. Families sometimes see a large, unused Capacity Building total and assume it can cover support worker hours or everyday costs when Core funding runs low. It generally can't — Capacity Building funding is tied to its stated purpose (therapy, capacity building in daily living, employment support, and so on), not general everyday support. If your Core budget is running out but Capacity Building categories are underspent, that is a conversation for your NDIS planner or Local Area Coordinator about your plan's overall balance and goals — not a straightforward transfer.
This depends on what happens to your plan at its end date.
If the NDIA continues your existing plan rather than creating a new one, the NDIS states clearly: "Any unspent funding for NDIS supports from your previous plan can still be used. These funds will remain in the continued plan." Continued plans keep the same core and capacity building funding amounts as before (indexed for cost-of-living changes).
If instead you go through a full plan reassessment and are issued a genuinely new plan, the NDIS's own guidance does not state that leftover funding automatically carries across. Treat every new plan as a fresh budget built around your assessed needs going into that period, rather than assuming last year's unspent balance will simply reappear. If you have a significant unspent amount, raise it with your planner or LAC before your plan review — it may affect how your next plan is assessed.
Don't wait for a statement or a phone call — check it yourself, regularly.
A simple habit that helps: check your budget the same day each month, rather than only when something runs out. Catching a fast-draining Core budget in month four is far easier to manage than discovering it empty in month ten.
The NDIS budget covers disability-related supports, not general medication costs — those still run through Medicare and the PBS (Pharmaceutical Benefits Scheme) separately. If your family is juggling both, it can help to see medication co-payments side by side with the rest of the household budget. AskMyGP's free PBS Medication Price Checker (an independent tool, not part of the NDIS) looks up the current maximum co-payment for any PBS-listed medicine by brand or ingredient name:
