Monzo Bank UK — Complete Guide 2026

Monzo Savings Account 2026 — Pots, Interest Rates and ISA Options

Monzo doesn't have a separate savings account — savings live inside Pots. Here's how Monzo's Instant Access Pots, Locked Pots, and ISA work, what rates are on offer, and how they compare.

This guide is part of the Monzo hub, covering everything from Monzo’s core features to fees, limits, and savings options.

Monzo does not offer a traditional separate savings account. Instead, all savings live inside Pots — named sub-accounts within your Monzo account. Some Pots earn interest; others simply ring-fence money for a goal.

Monzo Pot Types — Summary

Pot type Interest Access Best for
Standard Pot 0% Instant Budgeting, goal-setting without interest
Instant Access Pot Variable AER (via partner banks) Instant Emergency fund, short-term saving
Locked Pot Fixed AER for term Locked until end date Fixed-goal saving, preventing impulse spending
Round-up Pot 0% (unless interest-bearing) Instant Automatic micro-saving
ISA Pot Variable or fixed AER Varies Tax-free savings up to £20,000/year

Instant Access Pots

Instant Access Pots are the closest Monzo has to a traditional easy-access savings account. Key facts:

  • Operated via Monzo’s partner banks (OakNorth, Aldermore, and others)
  • Interest is variable — the rate shown when you open the Pot applies until Monzo changes it
  • Money can be withdrawn instantly, 24/7
  • FSCS-protected separately under each partner bank’s £85,000 limit
  • Monzo Plus and Premium subscribers earn a higher rate — the standard free account earns a lower rate

Check the current rate in the Monzo app under Savings before opening. Rates change and are not guaranteed.

Locked Pots

Locked Pots pay a fixed interest rate in exchange for locking your money until a chosen end date:

  • Terms typically from 3 to 12 months
  • Higher rates than Instant Access Pots (as of 2026)
  • Cannot withdraw early without contacting Monzo support
  • Good for money you know you won’t need — holiday fund, annual bills, a tax pot

Monzo Cash ISA

Monzo has offered a Cash ISA to UK residents. The annual ISA allowance is £20,000 (2025/26). ISA availability and rates change — check the Monzo app under Savings → ISA for the current offer.

Should you use a Monzo ISA? Only if the rate is competitive. Monzo’s ISA rate is not always market-leading. Before opening, compare against:

  • NS&I
  • Marcus by Goldman Sachs
  • Chase UK
  • Dedicated building societies

Is Monzo Good for Savings?

Situation Verdict
Want to save inside your banking app ✅ Good — Pots are seamless
Need instant access ✅ Good — Instant Access Pot
Want a fixed rate ✅ Good — Locked Pot
Monzo Plus or Premium subscriber ✅ Better rates on Pots
Maximising interest on large balances ⚠️ Compare elsewhere — dedicated providers often pay more
Want a cash ISA ⚠️ Check rate vs. best-buy ISAs first

Monzo is convenient for savers who want everything in one app. For maximising returns on larger balances, dedicated savings accounts and ISA providers consistently outperform Monzo’s standard rates.

Round-Up Pots

Round-up Pots automate micro-saving: every card purchase is rounded up to the nearest pound and the difference is transferred to a chosen Pot. This is a useful way to build a savings habit with no manual effort. You can enable round-ups in the Monzo app under Account → Round-ups.
