Monarch Money vs Tiller: Modern App vs Spreadsheet (2026 Verified Comparison)

Tiller and Monarch are both serious personal finance tools, but they’re philosophically opposite. Tiller automates your transactions into Google Sheets or Excel — your data lives in spreadsheets you fully control. Monarch is a polished SaaS app with Sankey diagrams, Goals 3.0, AI Assistant, and partner Shared Views.

Both have devoted user bases. The choice between them comes down to one question: do you love spreadsheets? If yes, Tiller. If no, Monarch.

Side-by-side

What Tiller does well

Tiller’s selling point is genuinely unique in the budgeting category: your data lives in your own spreadsheets that you fully control.

Tiller’s strengths:

• Total customization — it’s a spreadsheet; you can change anything
• Data portability — your data is in Google Sheets / Excel files you own forever
• AutoCat — Tiller’s powerful auto-categorization engine, fully customizable rules
• No vendor lock-in — if Tiller ever shut down, you keep your spreadsheets
• Community templates — large library of budget, debt payoff, net worth, retirement templates contributed by users
• 21,000+ institutions — broader connection support than most apps
• Power-user features — pivot tables, formulas, charts, conditional formatting, anything Sheets/Excel can do
• Daily email summary — sent every morning with account activity
• Google Sheets collaboration — share with family, accountant, partner via Google’s normal share permissions
• U.S.-based customer support — responsive and knowledgeable

For users who think in spreadsheets, Tiller is genuinely the most powerful tool in personal finance.

What Tiller doesn’t do well

Honest limitations:

• No mobile-native experience — you use Google Sheets / Excel mobile apps, which work but feel clunky for budget review on the go
• Setup learning curve — picking a template, configuring AutoCat, customizing for your needs takes hours, not minutes
• No polish — it’s a spreadsheet. Beautiful spreadsheets exist; Tiller’s templates are functional but not visually impressive
• No Sankey out of the box — you can build one in Sheets, but it’s manual
• No native Goals system — you build goal tracking via templates and formulas
• Limited investment depth — pulls balances but not holdings-level analysis (vs Monarch Plus’s Morningstar integration)
• No AI Assistant — for natural-language queries, Tiller has nothing comparable
• No native couples/household experience — you share spreadsheets via Google Drive permissions, but there’s no per-account ownership filtering

For users who want a polished modern app, Tiller feels like a relic.

Round-by-round

Round 1: Price (Tiller wins narrowly)

Tiller: $79/yr flat. Monarch: $99.99/yr list, $49.99/yr first year with SMARTMONEY (renews at $99.99).

For first-year cost, Monarch with SMARTMONEY is cheaper ($49.99 vs $79). For long-term cost, Tiller is cheaper ($79/yr forever vs Monarch’s $99.99/yr after first year).

For couples, Monarch is meaningfully cheaper because one subscription covers both partners. Tiller is single-user (you can share spreadsheets but you have one Tiller subscription).

Round 2: Customization (Tiller wins decisively)

It’s not even close. Tiller is a spreadsheet — you can customize anything. Monarch has structured customization (categories, rules, custom budgets, custom reports) but you can’t fundamentally change how the data flows.

If you want to model “what if I increase 401(k) contributions by 2% and reduce restaurants by $200/month” with custom formulas across years, Tiller is the tool. Monarch’s Plus Forecasting can do this but with less flexibility than a custom spreadsheet.

Round 3: Polish and UX (Monarch wins decisively)

Monarch is a modern web/mobile app with thoughtful UX. Tiller is automated spreadsheets. For users who want their financial app to feel polished, Monarch is the obvious pick.

This isn’t a knock on spreadsheets — Tiller’s spreadsheets are well-designed for what they are. But “well-designed spreadsheet” still feels different from “well-designed app.”

Round 4: Mobile experience (Monarch wins)

Monarch has full-featured iOS and Android apps. Tiller’s mobile experience is using Google Sheets / Excel mobile apps to view and edit spreadsheets — functional but clunky.

For couples doing weekly money reviews on their phones, Monarch is meaningfully better.

Round 5: Couples / household (Monarch wins)

Tiller can be shared via Google Sheets permissions, but there’s no per-account ownership filtering or Shared Views architecture. You and your partner look at the same spreadsheets without filtering tools.

Monarch’s Shared Views with ownership filtering is built specifically for couples. For more, see How to Share Finances With a Partner in Monarch.

Round 6: Goals and forecasting (Monarch wins)

Monarch’s Goals 3.0 system is built-in and integrated with the budget. Tiller relies on community templates for goal tracking — they exist but aren’t as integrated.

Monarch Plus’s Forecasting feature is unique to Monarch in this comparison. Tiller can model future scenarios but you build the model yourself.

Round 7: Investment tracking (Monarch wins)

Monarch has solid investment tracking at Core ($49.99) and excellent at Plus ($299/yr Morningstar integration). Tiller pulls balances but doesn’t analyze holdings, asset allocation, or fund classifications.

For investment-focused users, neither is best (Empower wins that comparison) — but between Monarch and Tiller, Monarch handles investments better.

Round 8: Data ownership and portability (Tiller wins)

Tiller’s spreadsheets are yours forever. If Tiller shuts down tomorrow, you keep all your data in Google Sheets / Excel. If you want to move to a different tool, you have full data portability.

Monarch supports CSV export for data portability, but the data lives in Monarch’s cloud during use. There’s some lock-in (custom categories, rules, goals don’t migrate easily).

For users who specifically want data ownership outside any vendor’s cloud, Tiller is the right pick.

Who should pick Tiller?

Tiller is the right pick if:

• You love spreadsheets and think in pivot tables
• You want total customization and have time to invest in setup
• You specifically value data ownership outside vendor clouds
• You’re willing to give up polish for power
• You’re a single user (couples support is weak)
• You want to integrate with other spreadsheet workflows (your existing investment tracker, business spreadsheet, etc.)
• You want the lowest sustainable cost over many years
• You enjoy the tinkering aspect of personal finance

Who should pick Monarch?

Monarch is the right pick if:

• You want a polished modern app with no setup friction
• You’re a couple or household needing shared finances
• You value the Sankey diagram and AI Assistant
• You’re mobile-first or do significant review on phone
• You don’t want to maintain a spreadsheet system
• You want investment depth bundled with budget
• You want a tool the whole family can use without a learning curve
• You prefer a curated experience over total flexibility

Common questions

Can I use both Monarch and Tiller?

Yes — they’re separate services. Some users do this temporarily during evaluation; few keep both long-term because the data overlaps.

Does Tiller have a couples mode?

Sort of. You can share Tiller spreadsheets with your partner via Google Sheets permissions. There’s no per-account ownership filtering, but you can both view and edit the same spreadsheets. For couples doing equal-partner budgeting, this works. For couples wanting yours/mine/ours filtering, Monarch is better.

Can I migrate from Tiller to Monarch?

Yes via CSV export from your Tiller spreadsheet, then import to Monarch. The transition is smooth because both use the same column structure (date, description, amount, category).

Does Tiller work with Excel or just Google Sheets?

Both. Tiller supports Google Sheets natively and Microsoft Excel via a separate but equivalent integration. Some features (notably AutoCat AI categorization) ship to Sheets first.

Will Tiller be around in 5 years?

Tiller has been operating since ~2017 and has grown steadily. They’re privately held, profitable, and have an engaged user base. Same applies to Monarch (founded 2018, well-funded). Both are likely to be around long-term.

Does Monarch support custom formulas like Tiller?

No — that’s not the model. Monarch has structured customization (custom categories, transaction rules, custom reports) but no spreadsheet-style formulas. If formula flexibility matters to you, that alone tips toward Tiller.

What about Tiller’s daily email summary?

Useful for quick check-ins. Monarch’s equivalent is the weekly summary email + AI Assistant. Daily-frequency users prefer Tiller’s email; weekly users find Monarch’s pattern fine.

Is Tiller secure?

Yes — Tiller doesn’t store your bank credentials (it uses Plaid), and your spreadsheet data lives in your own Google Drive / OneDrive. Same general security architecture as Monarch and other modern aggregators.

Do I need spreadsheet skills to use Tiller?

Basic spreadsheet skills (entering data, simple formulas) help. Advanced features (custom dashboards, complex AutoCat rules) require intermediate skills. If “I just want a budgeting app that works” is your sentiment, Tiller’s setup phase will feel like work.

What about Tiller vs Monarch for small business / freelancers?
