Best Portfolio Tracker for Bonds (2026)

Why Bond Investors Need a Different Tracker

Most portfolio trackers were built for equity investors. You enter a stock ticker, the tool pulls the price from Yahoo or Google Finance, and your P&L updates automatically. Bonds do not work that way. A bond's theoretical value changes every time the yield curve moves, not just when a dealer happens to post a quote. A bond that cost you 98 in January could reasonably be worth 96 or 100 in April depending on what happened to rates — and most portfolio trackers will still show you 98 because nobody re-entered the price.

A real bond portfolio tracker does five things a general tracker skips: it reprices against live yield curves, it tracks credit spreads, it computes YTM and duration correctly, it visualizes the maturity ladder, and it projects forward coupon income. We reviewed five popular tools against these criteria, plus CUSIP/ISIN support and multi-currency handling. Here is how they stack up.

Review Criteria

Our goal is not to pick a single winner for every investor — it is to help you match the right tool to your actual bond workflow. Each review below flags concrete pros and cons against the criteria above, and the decision boxes at the bottom summarize which tool fits which use case.

The Rankings

1

AllInvestView Editor's Pick

Purpose-built bond tracker with live central bank yield curves

Editor's Choice

AllInvestView is the only tracker on this list that was built from the ground up with bond pricing in mind. It pulls live yield curves from four central banks (Bank of Canada, US Treasury, ECB, Bank of England), reprices using QuantLib with the correct day-count conventions, and tracks implied credit spreads per bond. CUSIPs are auto-converted to ISINs. The maturity ladder and coupon calendar are first-class features, not afterthoughts. Multi-currency is native. And the core bond tracker is free.

Pros

• Live repricing from 4 central banks, no lag
• QuantLib-grade pricing engine
• CUSIP + ISIN + credit spread editing
• Household consolidation for advisors
• Free tier covers core bond tracking

Cons

• PDF branded reports not yet available
• No real-time tick data (end-of-day curves)

2

Sharesight

Strong equity tracker with partial bond support

Partial Support

Sharesight is a solid general-purpose tracker with very good tax reporting, especially for Australian, UK, and New Zealand investors. Bond support exists but is limited — you can enter bonds as holdings, but there is no yield curve repricing, no credit spread tracking, and the maturity ladder and coupon calendar have to be built manually. If you hold a small number of bonds alongside mostly equities, Sharesight handles the cost-basis side well. If bonds are a core allocation, it will frustrate you.

Pros

• Excellent tax reports (AU, UK, NZ)
• Clean multi-asset portfolio view
• Good multi-currency handling

Cons

• No yield curve repricing
• No credit spread tracking
• Manual price updates for bonds

3

Fidelity (in-app tools)

Strong for Fidelity customers, not portable elsewhere

Platform-Bound

Fidelity's in-app bond tools are genuinely good for customers holding bonds with Fidelity. Bond screener, maturity ladder builder, and yield calculations are all built in. The obvious limitation: it only tracks bonds held in Fidelity accounts. If you have holdings at a second broker, a trust account elsewhere, or an international account, Fidelity's tools stop at the border.

Pros

• Integrated with Fidelity bond inventory
• Built-in bond ladder tool
• Free for Fidelity customers

Cons

• Only tracks Fidelity-held bonds
• No cross-broker consolidation
• Limited credit spread analytics

4

BondbloX

Bond-focused but narrow geographic scope

Niche Focus

BondbloX is an interesting specialist platform focused on fractional bond investing, mainly for Asian and some international issues. Their portfolio manager handles what you buy on their platform well, but it is not a general-purpose tracker — you cannot easily import holdings from elsewhere, and Canadian and US government bond curve integration is not a focus.

Pros

• Bond-specific features
• Fractional bond investing

Cons

• Narrow coverage (mostly Asia)
• Limited curve coverage
• Platform-bound holdings

5

Excel / Google Sheets

The default, with all the usual spreadsheet pain

Default Baseline

Most bond investors end up here by default. A spreadsheet can do anything you want it to do — in theory. In practice, maintaining accurate YTM calculations, pulling current yield curve data, computing accrued interest with the right day-count convention, and keeping a maturity ladder up to date is a full-time job nobody wants. For a handful of holdings it works. Past that, it does not.

Pros

• Free
• Fully customizable

Cons

• Manual everything
• Error-prone (day counts, accruals)
• No yield curve data
• High maintenance cost

How Bond Repricing Actually Works — A Walkthrough

The methodology above is easy to describe in abstract — "benchmark curve plus implied spread" — but a concrete example makes it obvious why this approach is more honest than storing a stale purchase price. Here is a step-by-step walkthrough of how AllInvestView prices a real Government of Canada bond today.

Currency:        CAD → Bank of Canada Government of Canada curve
Tenor to maturity: ~14 months → interpolate between 1Y (2.55%) and 2Y (2.79%)
Interpolated benchmark yield: ~2.60%

Trade price: 97.50 → YTM (semi-annual, 30/360): ~3.45%
Spread over benchmark:        3.45% − 2.60% = +85bp

Today's interpolated benchmark: 2.58% (auto-refreshed from BoC Valet API)
Target yield:  2.58% + 0bp spread = 2.58%
Theoretical price: 98.55 (computed by QuantLib PV engine)

YTM: 2.58%   Duration: 1.15   Accrued: $0.52   Spread: 0bp
Unrealized P&L: (98.55 − 97.50) × face = +1.05 per $100

Every number above is either visible on the bond report or configurable by the user. The benchmark curve comes straight from the Bank of Canada Valet API — you can verify the interpolated yield yourself against the published data. QuantLib handles the present-value math with the correct day-count convention and compounding basis. And the implied spread is editable, so if your dealer gives you a fresh mark, you enter the spread, hit reprice, and the theoretical price updates immediately. That transparency is the thing no spreadsheet or stale-price tracker can give you.
