Personal Retirement Corpus Calculator (5 Years)

Estimate a retirement corpus from monthly savings. This personal version uses a 5-year planning term as its starting point.

The "Future value" result is the total your monthly savings could grow to by retirement after 5 years at the rate you entered, including both the money you paid in and the growth earned on it; a larger result over a longer term shows how regular saving plus compounding builds up over time.

Formula

Corpus uses the monthly rate and number of monthly savings to grow each saving with interest.

How it works

Starting earlier matters more than saving a little more later, because interest has longer to compound.

Worked example

Monthly saving $500, annual rate 7%, term 5 years. First, the monthly rate is 7% divided by 12, which is 0.0058333, and the number of payments is 5 times 12, which is 60. Using the corpus formula, the future value is $500 times (1.417625 minus 1) divided by 0.0058333, which is $35,796.45. Over 60 payments the person deposits $30,000.00 in total, and interest adds $5,796.45 to reach the corpus. That interest is 16.2% of the corpus, so most of this short-term corpus is the person's own saving, not interest, because compounding has had only 5 years to work.

Who this term suits for a person: a person near retirement who wants to top up an existing pension, or a late starter who wants to build a habit and a small bridge fund. For example, someone at 60 who already has a pension could save $500 a month for 5 years to cover the first years of retirement costs, or to pay off a remaining bill before stopping work. The trade-off is clear: $35,796.45 is a useful top-up, not a full retirement fund on its own, so it must be checked against pension income and living costs, not treated as enough by itself.

FAQs

When should I start saving for retirement?
As early as possible. Time in the market allows compounding to do more of the work.

Is this personal calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Is $35,796.45 enough to retire on after 5 years?
On its own, usually no. $35,796.45 is a top-up, not a full retirement fund, and it must be added to pension income, other savings, and any state pension. Work out yearly living costs first, then see how many years $35,796.45 would actually cover, before counting on it alone.

Why is interest only $5,796.45 after 5 years?
Because compounding needs time. Over 60 payments the balance is still small for most of the term, so interest has little to earn interest on. The same $500 a month earns far more interest over 20 or 30 years, when the balance is much larger and each month's interest is added to it.

Can I catch up a late start by saving $500 a month for only 5 years?
It helps, but it does not close a large gap on its own. A late starter may also need to save more than $500 a month, delay retirement by a few years, cut retirement spending, or check pension entitlements. This calculator assumes a fixed 7% rate and no fees, so a real plan should be checked with a qualified adviser.
