Investment growth calculator Canada

Project how a lump sum plus monthly contributions could grow over time — and, just as important, see that future balance in real after-inflation dollars so you know what it would actually buy in today's money.

How to project investment growth

Investment growth comes from three things working together: the money you start with, the money you keep adding, and the return those dollars earn, compounded over time. Each contribution begins its own compounding journey the day it lands, so a steady monthly habit can quietly build more of your final balance than a single big deposit — especially over a long horizon.

Future value = lump sum grown for the full horizon  +  the grown-up value of every contribution along the way

  • Time dominates: doubling your years usually does more than doubling your contribution.
  • Contributions compound too: each one you add starts earning from the day you invest it.
  • Rate is a multiplier: even one or two extra percent a year compounds into a large gap over decades.
  • Inflation works in reverse: it shrinks what that future balance can buy, which is why the today's-dollars view matters.

Why today's dollars matter

A big future number is exciting, but it can mislead. If your projection ends at $459,854 in 25 years, that's not 25-years-from-now you holding today's purchasing power — at 2.5% inflation it would buy roughly what $248,041 buys today, about 46% less. That's why this calculator always shows both: the raw future value and the inflation-adjusted real value. Plan around the real number and you'll set targets that actually fund the retirement you picture.

A quick shortcut: the Rule of 72

Divide 72 by your return to estimate how long your money takes to double: about 12 years at 6%, 9 at 8%, 18 at 4%. Run the same trick with your inflation rate to see how fast prices double — at 2.5%, roughly every 29 years. The gap between those two doubling times is, in a nutshell, your real growth.

Keep more of the growth

Start early, automate it

  • Time beats timing: the earliest dollars compound the longest, so starting now matters more than starting big.
  • Automate contributions so they happen every month without a decision.
  • Step them up a little each year as your income grows.

Shelter and protect it

  • Use registered accounts: a TFSA keeps growth tax-free; an RRSP defers the tax.
  • Mind the fees: a 2% MER can erase a large slice of the growth shown here.
  • Diversify cheaply with low-cost index funds so more of the return reaches you.

What this calculator doesn't model

This is a simplified, straight-line projection. It assumes a constant return every year and ignores tax, investment fees, and the real-world risk that a bad early stretch of returns can do lasting damage. Use it to feel the shape of growth, not as a precise forecast. Pair it with our compound interest calculator, investment fee calculator and asset allocation calculator, plus the couch potato investing guide and RRSP vs TFSA guide.

Frequently asked questions

What does this investment growth calculator do?

It projects how a portfolio could grow from a lump sum plus regular monthly or yearly contributions, at an expected annual return, over a number of years. Unlike a plain growth tool, it shows the result two ways: the raw future value and the same balance in today's dollars after inflation — so you can see what your money would actually buy, not just a big future number.

Why does the calculator show "today's dollars"?

Because inflation quietly shrinks what a dollar buys. A portfolio worth $450,000 in 25 years will not feel like $450,000 does today — at 2.5% inflation it buys closer to what $240,000 buys now. Showing the real, after-inflation value is the honest way to judge a long-term plan, and it's the main thing that sets this investment growth calculator apart from a simple compound-growth tool.

What rate of return should I use?

Use a long-run average for what you actually hold. A balanced portfolio of stocks and bonds has historically returned roughly 5–7% a year before inflation; an all-equity portfolio more, with bigger swings; GICs and savings less. Many Canadians plan with 6% and sanity-check a conservative 4–5%. Remember this is a straight-line estimate — real markets zig-zag, and a bad early stretch matters more than the average suggests.

Does it account for taxes and fees?

No — the projection is before tax and before investment fees. In a TFSA growth is tax-free and in an RRSP it is tax-deferred, but in a non-registered account you pay tax along the way. Fees bite too: a 1–2% MER can quietly erase a large slice of the growth shown here. See our investment fee calculator to measure that drag, and the RRSP vs TFSA guide to choose where to hold it.

How much difference do monthly contributions make?

A great deal — often more than the starting lump sum over a long horizon. Because every contribution begins compounding the day it lands, steady monthly investing builds a surprisingly large share of the final balance. Try setting the lump sum to $0 and the monthly amount to what you can realistically save: for most people, consistent contributions plus time do more of the work than a single big deposit.

What is a realistic inflation rate to use?

The Bank of Canada targets 2% inflation, and it has averaged roughly 2–3% over the long run, with occasional spikes. For the today's-dollars view, 2.5% is a reasonable middle estimate. Using a higher number makes the real value smaller and your plan more conservative — a useful stress test if you are projecting decades out.

Should I increase my contributions over time?

If your income rises, increasing contributions even slightly each year compounds powerfully. The contribution step-up in Advanced options models this: set it to the raise you expect — say 2–3% a year — and your contribution grows automatically. Because each larger amount still has years to compound, a modest annual step-up can add a meaningful sum to the final balance versus a flat contribution.

How accurate is a long-term projection like this?

Treat it as a shape, not a forecast. It assumes a constant return every year, which never happens — markets rise and fall, and the order of those returns (especially early on) changes the outcome. Use it to compare scenarios and feel how contributions, rate, time and inflation interact, then revisit the numbers yearly. It is a planning aid, not a guarantee.

Where should I hold these investments?

For most Canadians the order is TFSA first (tax-free growth and flexible withdrawals), then RRSP (tax-deferred, good in higher-income years), then non-registered once those are full. Sheltering the growth keeps far more of the compounding shown here. Our RRSP vs TFSA guide and couch potato investing guide walk through how to set this up simply with low-cost index funds.

Educational tool, not financial advice. Projections assume a constant annual return and regular contributions, and ignore tax and investment fees. The today's-dollars view is illustrative — the inflation adjustment uses the single rate you enter, and actual inflation and returns vary year to year and are not guaranteed.
