Getting started: which is easier?
Setup verdict: Draw
Both Plum and Moneybox take just a few minutes to set up. You download the app, link your bank using Open Banking, and you’re ready to go. No credit checks, no paperwork.
Moneybox is slightly simpler upfront because there are fewer plan choices. Plum asks you to think about subscriptions earlier — but that’s not a dealbreaker.
Saving automatically: which app does it better?
Autosaving verdict: Plum
Plum is built around automation. It actively decides how much you can afford to save using AI, then moves money for you in the background. You can adjust the intensity, pause it, or add rules like payday saves and round-ups.
Moneybox relies more on you deciding how much to save. Round-ups are excellent, but outside that, saving is mostly manual.
If saving doesn’t come naturally to you, Plum does more of the heavy lifting.
Making your money work: savings vs investing
Savings verdict: Plum
Investing verdict: Moneybox
Plum shines if you want to keep money in cash. It usually offers competitive easy-access savings and doesn’t push you into investing.
Moneybox is clearly investment-first. It offers:
- Stocks & Shares ISA
- Cash ISA
- Lifetime ISA (cash and invested)
- pension (SIPP)
- notice accounts
If your goal is investing for the long term — especially using a Lifetime ISA — Moneybox is the stronger option.
Cash ISAs and Lifetime ISAs
ISA verdict: Moneybox
Both apps offer a Cash ISA, and rates change frequently.
The big difference is that Moneybox offers a Lifetime ISA, while Plum does not. If you’re saving for your first home or retirement, this alone may decide it.
Plum’s ISA is simpler and easier to manage — Moneybox’s is more powerful but more restrictive.

Costs and subscriptions: which is better value?
Cost verdict: Depends on your goal
Plum:
- free for basic saving
- paid plans unlock investing and higher rates
Moneybox:
- £1 monthly fee for investing
- percentage-based platform fees apply
- fee waived on larger balances
If you’re only saving, Plum is cheaper.
If you’re investing seriously, Moneybox can make sense — but it’s expensive on small balances.
Referral schemes: which pays better?
Referral verdict: Plum
Plum regularly runs referral offers, often rewarding you if you refer multiple friends.
Moneybox referral offers are inconsistent and usually modest when they appear at all.
If referral bonuses matter, Plum wins comfortably.
Extra features: anything worth shouting about?
Extras verdict: Draw
Moneybox offers calculators and learning tools around pensions and home buying.
Plum offers budgeting tools, saving goals and behavioural nudges on paid plans.
Neither app’s extras are game-changing — the core features matter far more.
Overall winner: Plum vs Moneybox
Overall verdict: Plum (for most people)
This is close, but Plum wins for the average user.
It’s easier to use, genuinely helpful for people who struggle to save, and doesn’t force you into investing or subscriptions. Moneybox is excellent for Lifetime ISAs and long-term investing — but it’s slower, more restrictive, and more expensive on small balances.
Choose Plum if you want:
- saving automated without effort
- flexibility and control
- a strong free option
Choose Moneybox if you want:
- a Lifetime ISA
- investing and pensions in one place
