What is Savings Calculator?

Searchers compare savings rates, cash ISA returns, monthly interest, large balance interest, and real return after inflation. The page combines a practical calculator with an explanation, examples, tables, and internal links so users can move from one quick answer to a better understanding of the method.

UK context matters. GOV.UK lists the 2026 to 2027 adult ISA allowance as £20,000, and the Junior ISA limit as £9,000. Bank of England Bank Rate was 3.75% in early June 2026, while ONS reported CPI inflation of 2.8% for April 2026. These figures are useful reference points, but account rates, fees, tax treatment, and investment performance can change.

How to use the Savings Calculator

1. Enter the main value, expression, equation, balance, return, rate, or fraction.
2. Choose the mode that matches your task, such as equation solving, compound growth, degree/radian mode, or fraction operation.
3. Review the highlighted result and the plain-English working below it.
4. Click Save Result to lock Scenario A, then change inputs to compare Scenario B.
5. Use Share Link or Print when you want to keep the result for revision, records, or discussion.

Formula and method

Future savings value = starting balance x (1 + r/n)^(nt) + regular deposit x [((1 + r/n)^(nt) - 1) / (r/n)]. Real value divides the future balance by expected inflation growth.

Worked example

Example: £10,000 plus £250 per month at 4.5% for 5 years grows from contributions of £25,000 to an estimated balance above the amount saved because interest compounds.
