1. What is the Savings Calculator?

The Savings Calculator UK Monthly estimates the future value of your savings based on initial principal, monthly contributions, annual interest rate, and time period. It helps you plan your financial goals and understand how compound interest works over time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula with monthly contributions:

\[ FV = P \times (1 + r / 12)^{(12 \times t)} + PMT \times \left[\frac{(1 + r / 12)^{(12 \times t)} - 1}{r / 12}\right] \]

Where:

\( FV \) — Future value (GBP)
\( P \) — Initial principal (GBP)
\( r \) — Annual interest rate (decimal)
\( t \) — Time in years
\( PMT \) — Monthly payment (GBP per month)

Explanation: The formula calculates compound interest on the initial principal plus the future value of a series of monthly contributions.

3. Importance of Savings Calculation

Details: Understanding future savings value is crucial for financial planning, retirement planning, and achieving long-term financial goals. It helps individuals make informed decisions about saving and investing.

4. Using the Calculator

Tips: Enter initial principal in GBP, annual interest rate as a percentage, time in years, and monthly contribution amount. All values must be valid (non-negative numbers, time > 0).
