Savings Rates After the 4% Rate Rise: Your £10,000, Calculated

Savings rates after the 4% rate rise: what £10,000 earns

The Bank of England raised Bank Rate from 3.75% to 4% on 5 November 2026, its first rise in more than three years. Yet the average easy access savings account paid only about 2.56% at the start of November, and big-bank flexible accounts averaged 1.16%, according to Moneyfacts. On £10,000 that is the difference between earning £116 and more than £500 a year, before inflation of 3.5% quietly takes its share.

Savers are searching "will my savings rate go up?" this week. Some providers have already confirmed rises (Nationwide's variable rates go up by up to 0.25 percentage points from 1 December, and Santander's Bank Rate-linked accounts rise on 2 December). Many others pass on rises slowly, or not at all. Here is what the numbers mean for your own pot, and a checklist to make sure the rise reaches you.

What changed on 5 November

The Monetary Policy Committee voted 8 to 1 to raise Bank Rate by 0.25 percentage points to 4%; one member wanted 4.25%. The Bank said inflation, 3.5% in September, is expected to rise to about 4.5% in early 2027 and about 5% in the second quarter of 2027 before falling back. The next decision is on 17 December 2026. We looked at the mortgage side in Bank of England Rate Rise to 4%: 3 Households, One Year. This article is about the other side: your savings.

Your £10,000 at five different rates

The table shows one year's interest on £10,000 at five rates in today's market, and what that money is worth after inflation. "Real gain" compares the year-end balance with £10,000 grown at 3.5% (today's inflation) and at 5% (the Bank's mid-2027 expectation).

Rate on £10,000 Interest in a year Real gain at 3.5% inflation Real gain at 5% inflation
1.16% (big-bank flexible average) £116 -£226 -£366
2.56% (average easy access) £256 -£91 -£232
4.00% (competitive easy access) £400 +£48 -£95
5.21% (top 1-year fixed, 10 Nov) £521 +£165 +£20
5.30% (top 2-year fixed, per year) £530 +£174 +£29

Our calculations, before tax, assuming the rate stays fixed for 12 months. Top fixed rates from the Moneyfacts comparison table at 16:25 on 10 November 2026; rates change daily.

One year's interest on £10,000

Big-bank flexible 1.16%
£116
Average easy access 2.56%

Competitive easy access 4.00%

Top 1-year fix 5.21%

Leaving £10,000 in a 1.16% account while inflation runs at 3.5% costs about £226 of buying power in a year. That is the real price of not switching.

Make the rate rise work for you

A better rate only helps if you know which money can be locked away and which has to stay instantly available. The Matriarch's Money Reset, Step III: Own the System helps you build that structure.

  • Split your savings into buffers: bills, emergencies and goals, so you can fix one pot without touching the others.
  • Map a bills calendar so you know how much must stay in easy access each month.
  • Set up a household money system you review on a fixed date, such as each rate decision.

The tax catch: April 2027

Higher rates mean more interest, and more people will go over their Personal Savings Allowance: £1,000 of interest a year tax-free for basic-rate taxpayers, £500 for higher-rate taxpayers and £0 for additional-rate taxpayers. Some people on low incomes can also use the £5,000 starting rate for savings.

From 6 April 2027, tax on savings interest outside an ISA rises to 24% (basic), 44% (higher) and 49% (additional), up from 20%, 40% and 45%, as announced in the Autumn Budget 2026. Our earlier piece, Savings Tax Rise 2027: 24% Rate, covers it in detail.

How much you can save before tax applies At 2.56% At 4.00% At 5.21%
Basic-rate taxpayer (£1,000 allowance) £39,062 £25,000 £19,194
Higher-rate taxpayer (£500 allowance) £19,531 £12,500 £9,597

Our calculation: allowance divided by rate, outside ISAs, assuming no other savings interest.

Example: a higher-rate taxpayer with £20,000 at 5.21% earns £1,042. The £542 above her allowance costs £216.80 at 40%, or £238.48 at the 44% rate that applies to interest taxed in 2027/28. A basic-rate taxpayer with £30,000 at 5.21% earns £1,563 and would pay £112.60 at 20%, or £135.12 at 24%. A cash ISA (allowance £20,000 for 2027/28, per ICAEW's Budget summary) keeps interest out of this calculation.

Your 6-point savings checklist this week

  1. Find your actual rate. Log in and note the AER on every account. If it is below 2.56%, you are below the market average.
  2. Check your provider's notice. Banks usually announce variable-rate changes by email or on their savings rates page. No notice by early December? Assume it is not passing the rise on.
  3. Keep your buffer liquid. Leave enough in easy access for bills and emergencies before you fix anything.
  4. Consider fixing spare money. Top 1- and 2-year fixes were above 5.2% on 10 November. Fixing means you usually cannot withdraw early.
  5. Watch bonus rates. Some headline easy access rates include a temporary bonus that drops off after months.
  6. Use regular savers for monthly saving. Some pay up to 8% (including bonuses) on small monthly deposits; £200 a month for a year at 8% earns about £104, because each deposit only earns for part of the year.

FAQ

Will my savings rate go up after the Bank of England rise?
Only if your provider passes it on. Rates on variable accounts are set by each bank. Nationwide and Santander have confirmed increases from 1 and 2 December; check your own provider's notice.

Is 4% a good savings rate in November 2026?
It beats the 2.56% easy access average and today's 3.5% inflation, but would fall behind if inflation reaches the 5% the Bank expects in mid-2027.

Do I pay tax on savings interest?
Only on interest above your Personal Savings Allowance (£1,000 basic rate, £500 higher rate, £0 additional rate), outside ISAs. Rates rise by 4 points from April 2027.
