Bond ladder calculator

A bond ladder is a portfolio of bonds (or GICs) that mature on a staggered, regular schedule — say one rung maturing each year for the next five years. Instead of putting all your money into a single bond, you spread it across several with different maturity dates. As each "rung" matures, you reinvest the proceeds at the long end of the ladder, keeping the schedule rolling. It's a simple way to earn a steady, predictable stream of fixed income without betting on the direction of interest rates.

A GIC ladder is the same idea built with Guaranteed Investment Certificates instead of bonds. You divide your money into equal pieces and buy GICs maturing in 1, 2, 3, 4 and 5 years. Each year one matures and you renew it as a new 5-year GIC. Because longer GICs usually pay more, laddering lets you capture higher rates while still having a portion come due every year. GICs are popular in Canada because they're CDIC-insured up to $100,000 per issuer and carry no market risk.

You split your total amount into equal rungs and buy a bond or GIC for each maturity year. This calculator divides your money evenly, applies a yield to each rung, and shows when each one matures and what it grows to. The key mechanic is rolling the ladder: when the nearest rung matures, you reinvest that cash into a new long rung. Over time every rung carries the longer-term yield, but you always have money maturing soon for income or flexibility.

Three big ones. Reduced interest-rate risk: because only one rung matures at a time, you're never forced to reinvest your whole portfolio at a single moment's rates. Steady income and liquidity: something comes due on a predictable schedule, giving you cash for spending or reinvestment. Simplicity: a ladder runs on autopilot — you just renew the maturing rung. The trade-off is that a ladder won't beat a lucky bet on rate direction; it's built for consistency, not for timing the market.

It depends on your time horizon and how often you want money maturing. A common retirement ladder runs 5 to 10 rungs spaced a year apart, so cash comes due annually. More rungs spread your reinvestment risk over more dates and smooth your average yield, but mean smaller individual pieces and a bit more admin. Fewer rungs are simpler but make you more exposed to the rate environment on each maturity date. Try different rung counts above to see how the schedule and average yield shift.

A bond ETF holds hundreds of bonds and is rebalanced for you, with daily liquidity but no fixed maturity date — its price moves with rates. A bond ladder holds individual bonds or GICs you intend to hold to maturity, so you know exactly what each rung pays and when you get your principal back. Ladders give certainty and a defined income schedule; ETFs give diversification and convenience. Many investors use both — a ladder for money they'll need on known dates, an ETF for the rest.

You get your principal back, plus any interest. With a rolling ladder you reinvest that cash into a new bond or GIC at the longest rung — for a 5-year ladder, the maturing 1-year rung becomes a fresh 5-year one. That keeps the ladder the same length and gradually moves every rung to the higher long-term yield. If you instead need the money for spending, you simply take the maturing rung as income and let the ladder shorten. Retirees often do a mix: spend some, reinvest the rest.

Yes — eligible GICs at a CDIC member institution are insured up to $100,000 per depositor, per insured category, per member. A GIC ladder at one bank is covered to that limit; spreading rungs across several CDIC members (or using separate categories like a TFSA and an RRSP) can extend coverage well beyond $100,000. Individual bonds are not CDIC-insured, but Government of Canada and provincial bonds carry very high credit quality. Always confirm an issuer's coverage before assuming a rung is protected.

It's one of the most popular tools for it. A ladder turns a lump sum into a predictable schedule of maturing cash, which pairs naturally with annual spending. Many retirees build a ladder for the next several years of expenses so that a market downturn never forces them to sell stocks at a bad time — a direct buffer against sequence-of-returns risk. Pair the ladder with your overall asset allocation so the fixed-income sleeve is the right size.

That's exactly when a ladder shines, because it stops you from having to guess. If rates rise after you build it, your maturing rungs reinvest at the new higher yields. If rates fall, the longer rungs you already locked in keep paying their higher rate. By always having money maturing and money locked in, a ladder averages out the rate environment instead of betting on it. That's the whole point — you don't need a forecast to run one.

No — it's an educational tool. It models an equal-rung ladder with annual maturities and a simple yield curve, and it ignores taxes (interest is taxed as ordinary income outside a registered account), changing reinvestment rates, credit risk, and any early-redemption penalties. Real GIC and bond yields vary by issuer and term, so treat the output as an illustration.
