What If I Cut My Spending by 10%?
What if I cut my spending by 10%?
Ten percent of a month is easier to say than to find. On £1,800 of outgoings it is £180, which is either a serious squeeze or a serious surplus depending on rent. This experiment takes a monthly spend you type, applies a cut between 5% and 30%, and shows the pounds freed over a handful of years. The default rate is zero: the result is money not spent, not a portfolio. Households cannot cut rent, prescriptions or debt minimums as if they were streaming subscriptions, so the slider is a what-if applied to the total you claim is flexible. MoneyHelper’s budget planner is the proper place to test that claim.

What does that mean?
A 10% trim on £1,800 a month frees £180 a month, leaving about £1,620. Over 5 years that is £10,800 not spent. Whether those pounds exist in the real budget is a question for a statement, not for this slider.

A percentage has no manners
It does not know which line of the budget is already tight. Ten percent of groceries is a different decision from ten percent of a holiday fund. Enter a monthly figure that already excludes the bills you will not touch, and the cut becomes more honest. ONS family-spending publications show how an average household divides a week; they are a map, not your kitchen.
Five years of a quieter month
The default horizon is short on purpose. A 10% cut that lasts five years on £1,800 a month frees about £10,800 before any interest. That is enough to see, and not so long that the rest of life is assumed frozen. If you would actually save the difference, the monthly-savings experiment is the next page, with an optional rate.
Cuts are not the only lever
Takeaways, coffee, heating and buying less each pick a category instead of a percentage. Those are usually easier to act on than a 10% fog. Use this page when you want the scale of a broad trim, then go and name the line items.
How we calculated this
Monthly saving = monthlySpend × (cutPercent ÷ 100). That amount is run as end-of-month contributions for the chosen years. The default annual rate is 0%, so the headline is years × 12 × monthly saving. This experiment provides estimates for educational purposes and is not financial advice. Actual results vary depending on rates, fees, taxes, inflation and individual circumstances. Any rate above zero is an illustration and not guaranteed.
