- Only YNAB has a free tier, so it costs nothing to try first.
- Each has a real cost: Causal causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.; YNAB subscription priced exclusively in US dollars; international customers face unfavourable exchange rates
- They diverge on capability: Causal covers Variable-based modelling, YNAB covers Zero-based budgeting.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Causal
- Causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- Self-serve pricing is gone: the old causal.app pricing page now redirects to a Lucanet solution page, so what was a transparent product you could sign up for is an enterprise sales conversation with no published rate.
- The variable-based model is a genuine departure from spreadsheet thinking, so an accountant fluent in Excel must relearn how to express a model, and the team members who could previously all edit the forecast often cannot at first.
- Deep Excel compatibility is limited by design; complex existing workbooks with macros, circular references or heavy lookups do not import cleanly and have to be rebuilt, which turns a tool evaluation into a modelling project.
- Consolidation, statutory reporting and multi-entity currency handling are weaker than in dedicated corporate performance management suites, so a group with several legal entities usually needs Lucanet’s other modules alongside it, raising the real cost well past the planning tool alone.
YNAB
- Subscription priced exclusively in US dollars; international customers face unfavourable exchange rates
- Multi-currency support restricted to one currency per spending plan
- Bank import limited to select institutions in US, Canada, UK, and EU only
- Household plan can only be shared with up to 6 people; additional members cannot access shared plan

Answered from the vendors’ own pages
Causal: Does Causal still exist?
The product does, as Lucanet xP&A. The independent Causal brand and self-serve offering have been retired following the October 2024 acquisition.
YNAB: How much does YNAB cost per month?
YNAB costs $14.99 USD per month on a month-to-month basis, or $9.08 per month when paid annually as a $109 per year subscription. Both plans come with a 34-day free trial and no credit card required to start. Source: https://www.ynab.com/pricing
SourceCausal: What does it cost now?
Nothing is published. The former pricing page redirects to Lucanet, and the product is quoted as part of the Lucanet CFO Solution Platform.
YNAB: Can I share YNAB access with my family?
Yes, both annual and monthly YNAB plans include the ability to share access with up to 6 people at no additional cost, making it suitable for family budget management. Source: https://www.ynab.com/pricing
SourceCausal: Can I import my existing Excel model?
Simple workbooks import. Models with macros, circular references or heavy lookup chains have to be rebuilt around named variables, which is the real migration cost.
YNAB: Does YNAB offer a free trial?
Yes, YNAB provides a 34-day free trial with no credit card required to sign up. This trial gives full access to all budgeting features including account syncing, transaction tracking, goal-setting, and debt management tools. Source: https://www.ynab.com/pricing
SourceCausal: Is it a replacement for a consolidation tool?
No. It plans and forecasts. Statutory consolidation and multi-entity reporting sit in Lucanet’s other modules.
YNAB: Do students get a discount on YNAB?
Yes, verified college students receive a full year of YNAB access for free through YNAB's College Program. This allows eligible students to use all features at no cost for 12 months. Source: https://www.ynab.com/pricing
