Future value formula

FV = P(1 + r)^n + PMT × [((1 + r)^n − 1) / r]

P = current savings, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = months to retirement. The first term grows your balance; the second compounds every monthly deposit.

What is a retirement calculator?

A retirement calculator projects how large your savings could grow by the time you stop working. Starting from what you have saved today, it adds your regular monthly contributions and lets the whole balance compound at an assumed annual rate of return, month after month, until your chosen retirement age. The result shows two things that matter most for long-term planning: the projected total, and how much of it comes from money you put in versus growth earned along the way. Because compounding accelerates over decades, even modest contributions started early can grow into a substantial sum — which is exactly what this tool helps you visualise.

How to use it

1. Enter your current age and the age at which you plan to retire. 2. Enter how much you have already saved. 3. Enter the amount you add each month. 4. Set an expected annual rate of return. The projected balance at retirement updates instantly, along with a breakdown of contributions versus investment growth and a year-by-year chart. Try changing the contribution or return to see how sensitive the outcome is.

Formula and definition

The projection combines the future value of your current balance with the future value of your monthly contributions (an annuity): FV = P(1 + r)^n + PMT × [((1 + r)^n − 1) / r] Here P is your current savings, PMT is the monthly contribution, r is the monthly rate of return (annual rate ÷ 12) and n is the number of months until retirement. The first term grows your existing balance; the second adds up every monthly deposit and the compounding it earns. When the rate is zero the second term simply becomes PMT × n.

Reading your results

The headline figure is your projected balance at retirement in today's currency terms — it does not adjust for inflation, so its future purchasing power will be lower. The contribution-versus-growth split shows how much of the total your own deposits provided and how much compounding added; over long horizons growth often becomes the larger share, which is the power of starting early. Treat the number as a planning estimate, not a guarantee: real returns vary year to year and can be negative, and the result is highly sensitive to the rate you assume. Use it to compare scenarios, not to predict an exact figure.

Frequently asked questions

How much should I save for retirement? ▾

There is no single answer — it depends on your target lifestyle, other income such as pensions, and when you retire. A common rule of thumb is to save 10–15% of income, but use this calculator to test what your own contributions could build.

What rate of return should I assume? ▾

Long-run returns vary by asset mix and are never guaranteed. Many planners use a conservative real return for diversified portfolios, but markets fluctuate and can fall. Try a range of rates to see how much the outcome depends on this assumption.

Does this account for inflation or taxes? ▾

No. The projection is in nominal terms and ignores taxes and fees. To gauge future purchasing power, use a lower 'real' return (your expected return minus inflation), and remember that account type and local tax rules affect what you actually keep.

Why does starting early matter so much? ▾

Because compounding builds on itself. Money invested for longer earns returns on previous returns, so contributions made in your twenties can grow far more than the same amount added near retirement, even though the totals invested look similar.

This calculator provides a simplified, general projection for educational purposes only and is not financial, investment, or tax advice. It assumes a constant rate of return and ignores inflation, taxes and fees; real results will differ. Consult a qualified financial professional before making retirement decisions.
