Erasmus+ Budget Planning: A Practical Guide

Budget planning is where many otherwise strong Erasmus+ proposals fall apart. Applicants either under-budget key activities — making the project look underfunded and unrealistic — or over-request on vague line items that evaluators cannot justify. Both outcomes damage your score on financial capacity and project design.

This guide walks you through how Erasmus+ budgets actually work — by Key Action — what the unit cost logic means in practice, how to build a budget that is consistent with your work plan, and the most common mistakes to fix before you submit.

1. How Erasmus+ Funding Models Actually Work

Erasmus+ does not use one universal budget system, but it’s worth being precise about the distinction: both KA210 and KA220 are lump sum grants — you receive a fixed amount regardless of your actual itemized spending. Only KA1 works differently, calculating your grant automatically from unit costs. The real difference between KA210 and KA220 is how many lump sum tiers exist and how much detail you need to justify your choice.

2. Budget Breakdown by Key Action

Below is a reference overview of the main budget categories and grant limits for each Key Action. Exact unit rates vary by country and are updated each programme year — always verify against the current programme guide before submitting.

3. How Unit Costs Work — and Why They Matter

Unit costs are predefined rates set by the European Commission. For KA1, they directly determine your grant. For KA220, they’re used internally to build the cost estimate that justifies which lump sum tier you request. Either way, you don’t need to invoice or prove individual expenditure — what matters is that the activity happened and that the number of units (days, participants, trips) is accurate.

In KA220, the two most important categories for building your tier-justification budget are staff and travel:

Staff costs are estimated as: number of working days × daily rate for that role and country. Daily rates differ significantly by country and by staff seniority/role — a senior staff day in Denmark costs considerably more than the same role in Romania. Use the official rate tables from the current Erasmus+ Programme Guide when building your estimate.

Travel costs are estimated per trip using distance bands, from short trips of under 100km up to intercontinental trips of 8,000km or more. For most European partnership travel, journeys in the 500–1,999km range are common. Each trip should be estimated individually.

4. How to Build a KA220 Budget Justification Step by Step

Follow these steps in order. Each step feeds into the next — do not start entering numbers into the form until you have completed Steps 1–3 in a planning document first. Remember: this process determines which of the three lump sums (€120K / €250K / €400K) you request — it does not itemize a reimbursement.

Step 1 — Map activities to cost categories. Go through every activity in your work plan. For each one, identify which budget categories it requires: staff days, travel, accommodation, subcontracting, equipment or exceptional costs. If an activity requires no budget, flag it — it may be an oversight.

Step 2 — Assign staff days per activity per partner. For each activity, estimate how many working days each partner organisation needs to deliver it. Be specific: “Partner A: 5 days; Partner B: 3 days.” Sum staff days per partner across all activities to get total staff days. Multiply by the relevant daily rate for each partner’s country and role.

Step 3 — Estimate travel per meeting or event. List every transnational meeting, training event or pilot activity in your work plan. For each one, estimate travel costs per participant using the applicable distance band. Add accommodation at the destination country daily rate × number of nights.

Step 4 — Add subcontracting and other cost items. Identify any activities requiring outsourced services: translation, external evaluation, graphic design, website development, printing. Estimate costs based on market rates. For each subcontracted item, you will need to justify why it cannot be delivered by a partner organisation.

Step 5 — Total your estimate and select the closest tier. Sum everything from Steps 1–4. Choose whichever of the three lump sums (€120,000 / €250,000 / €400,000) most closely and credibly matches your estimated total — don’t round up to the next tier just because it’s available.

Step 6 — Check WP1 does not exceed 20%. Sum the total allocated to WP1 (Project Management) within your chosen lump sum. Divide by the total and multiply by 100. If the result exceeds 20%, redistribute some coordination-heavy staff days into the relevant implementation WPs.

Step 7 — Review partner budget distribution. Each partner should have a budget share proportionate to their workload. A partner leading two work packages should not have a smaller allocation than a partner who only contributes to one. Significant imbalances raise questions about genuine partnership.

5. How to Build a KA210 Budget

KA210 is even simpler than KA220: you choose between exactly two lump sum amounts — €30,000 or €60,000 — and demonstrate in your activity plan that the scope of work is proportionate to what you are requesting. No detailed cost breakdown table is required.

The evaluator’s question is simple: does this project — its partners, activities, outputs, timeline and target group — credibly justify the amount requested? A two-partner, 12-month project requesting €60,000 with three modest activities will raise questions. A two-partner, 18-month project with a validated toolkit, two pilot workshops per country and a dissemination event is a much more credible case for the same amount.

6. Budget vs Work Plan: The Consistency Check

The single most important budget quality check is whether the budget is fully consistent with the work plan. Evaluators read both sections — and inconsistencies between them are one of the most reliable indicators of a weak application.

Run these four checks line by line before entering your budget into the form:

Every activity that costs money appears in the budget. Go through the work plan activity by activity. If an activity involves a workshop, event, translation, expert fee or any other real expenditure, there must be a corresponding budget line. Activities that appear in the narrative but have no budget are either unfunded (suspicious) or overlooked (careless).

Every budget line links back to a specific activity. The reverse check is equally important. If a budget line — for example, €3,500 in subcontracting — has no corresponding activity in the work plan, the evaluator cannot justify it. Remove or relocate it.

Partner budget shares reflect partner workload. Cross-reference the work plan partner roles with the budget split. A partner leading WP3 and WP4 should have substantially more budget than a partner who only contributes to meetings.

Travel events in the budget match events in the work plan. Count the transnational meetings and in-person events in your work plan. Count the travel and accommodation lines in the budget. They must match — both in number and in estimated participant counts.

7. Most Common Budget Mistakes

WP1 exceeding 20% of the total grant. This is the most common KA220 budget error. Many coordinators load excessive staff days into Project Management without redistributing them into the WPs where the actual work happens. Check the percentage before submission.

Requesting equipment that is not project-specific. Laptops, printers and standard office equipment are not eligible unless the project has a specific, documented need — and even then, only the project-use proportion is eligible. A claim for six new laptops for a training project with no unusual technical requirement will likely be queried or refused.

Subcontracting core project tasks. Subcontracting is for specialist services that cannot reasonably be performed by a partner: professional translation, external evaluation, graphic design. Subcontracting the development of the main intellectual output — which is the core reason the partnership exists — raises a fundamental question about the added value of the partners.

Unequal partner budgets with no explanation. If one partner receives 70% of the budget and two others share the remaining 30%, evaluators expect the work plan to explain why. If the split is not justified by workload, it suggests the partnership is not genuinely balanced.

Using incorrect unit cost rates. Unit cost rates change annually. Using last year’s rates — particularly for staff or travel bands — produces an estimate that doesn’t hold up. Always download the current rate tables from the official Erasmus+ Programme Guide for the relevant call year.

Requesting the maximum tier without proportionate activities. Requesting €60,000 for a KA210 project with two partners, four activities and one output — or €400,000 for a KA220 project without the ambition to match — is disproportionate. Evaluators assess value for money even though the grant is a fixed lump sum. The activity plan must make the requested tier feel reasonable, not aspirational.

8. Budget Planning Checklist

• ✅ Correct funding model identified for your Key Action (automatic unit costs / lump sum)
