How This Calculator Works
Enter the RRSP lump sum, the annual return you expect, and how many years it stays invested. The calculator compounds the amount and shows the projected balance and total growth. Inside an RRSP, growth is tax-deferred — no annual tax on gains — until you withdraw, when withdrawals are taxed as income.
The Formula
Future Value of a Lump Sum
PV = present value, r = annual rate, n = number of years
Worked Example
$50,000 contributed to an RRSP and growing at 6% for 20 years reaches about $160,357 — roughly tripling, with $110,357 of tax-deferred growth. The RRSP (Registered Retirement Savings Plan) is Canada's main tax-deferred retirement account: contributions are tax-deductible (reducing your taxable income now), growth compounds tax-free inside the plan, and you pay income tax only when you withdraw in retirement — ideally when your income, and tax rate, are lower.
Key Insight
The RRSP is the cornerstone of tax-deferred retirement saving in Canada, and its power is the tax deferral working at both ends. A contribution is deductible against your current income, so it reduces this year's tax (and a large lump-sum contribution can generate a meaningful refund — which you can reinvest); growth then compounds with no annual tax drag; and you're taxed only on withdrawal, the bet being that your retirement tax rate is lower than your working rate. Key points this projection simplifies: contributions are capped by your RRSP deduction limit (a percentage of prior-year earned income up to an annual maximum, plus carried-forward room), so confirm your lump sum fits your available room — over-contributing beyond a small buffer incurs a penalty; the deduction can be carried forward to a higher-income year if beneficial; and withdrawals are fully taxable as income (with withholding tax at source), and the RRSP must be converted to a RRIF (or annuity) by the end of the year you turn 71, after which minimum withdrawals apply. RRSP vs TFSA: the RRSP gives an upfront deduction and is generally better when your current tax rate is higher than your expected retirement rate; the TFSA (after-tax in, tax-free out) is better when rates are similar or higher later, or for flexibility — many Canadians use both. Two special RRSP uses also let you withdraw tax-free temporarily: the Home Buyers' Plan and the Lifelong Learning Plan (repayable over time). This calculator shows the tax-deferred growth of a lump sum; remember the eventual withdrawal will be taxed, so the after-tax value is lower than the projected balance — but decades of tax-free compounding plus the upfront deduction make the RRSP a powerful tool when your rate will be lower in retirement.
The 18% income rule and the contribution ceiling
RRSP contribution room each year is the lower of: 18% of your previous year's earned income, or a fixed annual dollar ceiling set by CRA. For 2026 the dollar ceiling is $32,490 — so anyone earning more than $180,500 in 2025 is capped at $32,490 of 2026 RRSP room (not 18% of higher income).
Unused room carries forward indefinitely. Someone who earned $80,000 in 2025 but contributed only $5,000 of their $14,400 room generates $9,400 of carry-forward. Add this to subsequent years' fresh room until used. CRA's Notice of Assessment each year shows your cumulative deduction limit going forward.
Earned income includes employment income, self-employment income, rental income (net), and certain pensions — but NOT investment income (interest, dividends, capital gains) or government benefits. This is why high-income investors with significant non-employment income still have RRSP limits constrained by their earned-income share.
HBP and LLP: borrowing from your future self
Two CRA programmes let you withdraw RRSP tax-free for specified purposes. The Home Buyers' Plan (HBP) lets a first-time homebuyer withdraw up to $60,000 (raised from $35,000 in 2024) — or up to $120,000 for a couple buying jointly. Withdrawals are tax-free but must be repaid into the RRSP over 15 years, starting in the second year after the withdrawal. Miss a repayment and the unpaid portion is added back to your taxable income that year.
The Lifelong Learning Plan (LLP) lets you withdraw up to $10,000/year (max $20,000 total) to fund full-time post-secondary education for yourself or your spouse. Repayment is over 10 years, starting in the fifth year after the first withdrawal (or earlier if you stop being a student for 2 consecutive years).
Strategic note: HBP and LLP don't generate new deduction room — they're withdrawals from already-contributed money. The benefit is access to tax-sheltered savings without immediately paying tax. The cost is the missed compounding on the withdrawn balance during the repayment period — meaningful over a 15-year HBP repayment.
RRIF conversion at 71 and mandatory minimum withdrawals
By 31 December of the year you turn 71, your RRSP must be converted to a RRIF (Registered Retirement Income Fund), an annuity, or fully cashed out. RRIF is the standard choice — same tax-deferred growth, but with mandatory annual minimum withdrawals each year, all taxed as ordinary income.
Minimum withdrawal rates are set by age (using the older spouse's age if you elect): 5.28% at 71, rising each year through 6.82% at 80, 8.99% at 85, 13.62% at 90, then capped at 20% from age 95. The required dollar amount = age-rate × prior year-end RRIF balance.
Tax planning angle: large RRIF withdrawals push retirees into Old Age Security clawback territory (15% on income above the OAS recovery threshold), so smoothing withdrawals and using TFSAs for additional spending money are common strategies. Spousal income splitting (you can split eligible pension income, including RRIF withdrawals at 65+, up to 50% with spouse) is another lever. The Pension Income Tax Credit (~$2,000) applies to the first portion of RRIF income from 65+ — convert at least $2,000/year to capture it.
RRIF minimum withdrawal percentages by age
Applied to the RRIF balance at the prior 31 December. RRIF withdrawals are fully taxable as ordinary income. Use the older spouse's age if elected.
| Age | Minimum withdrawal % | On $500k RRIF | On $1M RRIF |
|---|---|---|---|
| 71 | 5.28% | $26,400 | $52,800 |
| 75 | 5.82% | $29,100 | $58,200 |
| 80 | 6.82% | $34,100 | $68,200 |
| 85 | 8.99% | $44,950 | $89,900 |
| 90 | 11.92% | $59,600 | $119,200 |
| 95+ | 20.00% | $100,000 | $200,000 |
There's no maximum on RRIF withdrawals — you can take more than the minimum, fully taxable. The minimum can be drawn from a single RRIF account if you have multiple.
Frequently Asked Questions
How is RRSP lump sum growth calculated?
The lump sum is multiplied by (1 + annual return) raised to the number of years. $50,000 at 6% for 20 years is $50,000 × 1.06²⁰ ≈ $160,357 — all compounding tax-deferred inside the RRSP until withdrawal.
How is an RRSP taxed?
Contributions are tax-deductible (reducing your taxable income now), growth compounds tax-free inside the plan, and withdrawals are taxed as income when you take them out — ideally in retirement when your tax rate is lower. So the tax is deferred, not eliminated; the after-tax value is less than the projected balance.
Is there a contribution limit?
Yes — your RRSP deduction limit is based on a percentage of your prior-year earned income up to an annual maximum, plus any carried-forward room. This calculator doesn't enforce it, so confirm your contribution fits your available room; over-contributing beyond a small buffer incurs a penalty. The CRA tracks your room.
RRSP or TFSA — which is better?
The RRSP gives an upfront deduction and is generally better when your current tax rate is higher than your expected retirement rate. The TFSA (after-tax contributions, tax-free withdrawals) wins when rates are similar or higher later, or when you want flexibility. Many Canadians use both, for different goals.
When must I withdraw from an RRSP?
You must convert the RRSP to a RRIF (or annuity) by the end of the year you turn 71, after which minimum annual withdrawals apply and are taxed as income. Before then, withdrawals are taxable too (with withholding at source), except temporary tax-free withdrawals under the Home Buyers' Plan or Lifelong Learning Plan, which must be repaid.

Methodology & Review
Future value is the lump sum compounded at the annual return over the period. It assumes the amount is contributed at once and left untouched at a constant return; growth is tax-deferred inside the RRSP. It ignores fees, the RRSP deduction limit, and the tax due on eventual withdrawal.
