PocketSmith vs Tiller 2026: Forecasting Tool or Spreadsheet Engine?

At a glance

Two Completely Different Ideas of What a Budgeting Tool Should Be

PocketSmith and Tiller get grouped together in budgeting app roundups constantly, but they solve different problems and the comparison only makes sense once that is clear. PocketSmith is a hosted app with its own interface built around a calendar view: every transaction, projected income event, and bill sits on a timeline that stretches forward, sometimes decades forward, so you can see the actual date your account balance is projected to dip below zero. Tiller does not have its own interface at all in the traditional sense. It is a daily data feed that pushes your bank transactions into a Google Sheets or Excel spreadsheet template that you own outright.

If you have never used either, the fastest way to decide which one fits is to ask yourself a single question: do you want a finished tool, or do you want your own spreadsheet with the tedious data entry automated? PocketSmith answers the first question. Tiller answers the second.

PocketSmith: What the Forecasting Actually Shows You

PocketSmith’s standout feature is genuinely rare among budgeting apps: long-range cash flow forecasting. The free tier limits how far ahead you can project, but the paid Foundation plan extends to 10 years, Flourish to 30 years, and the top Fortune tier to 60 years. This is not a gimmick. If you are planning a home purchase, a career change with a temporary income gap, or retirement contributions, seeing your actual projected balance on a specific future date, based on your real recurring transactions, is a genuinely different way to plan than looking at last month’s spending categories.

The calendar interface takes adjustment. Every bill, paycheck, and manually scheduled future transaction shows as an event on a specific day, and the app recalculates your projected balance forward from today across every day between now and your forecast horizon. Once it clicks, it is a powerful way to answer “can I afford this” questions with an actual date attached rather than a vague monthly average.

Tiller: What Daily Spreadsheet Feeds Actually Buy You

Tiller’s pitch is the opposite of a polished dashboard: it connects to more than 21,000 financial institutions and pushes a daily transaction feed into a spreadsheet template you fully control. The Foundation Template ships with pre-built sheets for spending trends, debt payoff tracking, savings goals, a monthly budget, and net worth, but because it is a spreadsheet, you can rebuild any of it, add your own formulas, or merge it with an existing personal finance spreadsheet you have used for years.

The core appeal is ownership and portability. Your data lives in your own Google or Microsoft account, not on Tiller’s servers in a proprietary format. If Tiller shuts down tomorrow, your spreadsheet and every year of transaction history stays exactly where it is. For anyone who has ever lost access to years of budgeting history because an app changed hands or discontinued a feature, that portability is worth real money on its own.

Pricing Head to Head

Tiller costs 79 dollars a year with a free trial period to test the daily feed before committing. PocketSmith’s pricing is tiered by forecast length and account limits: a free plan with basic functionality, Foundation around 9.95 dollars a month with 10-year projections, Flourish around 16.66 dollars a month with 30-year projections, and Fortune around 26.66 dollars a month for the full 60-year horizon and highest account limits.

On pure annual cost, Tiller at 79 dollars a year is cheaper than any paid PocketSmith tier except possibly a promotional rate on Foundation. But comparing them purely on price misses the point: you are not choosing between two versions of the same product at different prices, you are choosing between a finished forecasting tool and raw automated data feeding into work you build yourself.

Where Each One Actually Breaks Down

PocketSmith’s calendar view becomes harder to manage once your account count grows past a handful, particularly if you have multiple credit cards, several savings goals, and irregular freelance income all layered onto the same timeline. The forecasting is only as good as the recurring transactions you set up correctly; a badly configured recurring bill throws off every projection date after it.

Tiller’s limitation is exactly what you would expect from a spreadsheet-based tool: it will not build anything for you. The Foundation Template gives you a starting structure, but customizing it to match how you actually think about money, whether that is envelope budgeting, zero-based budgeting, or a simple percentage-based system, is on you. If you do not already have some comfort with spreadsheet formulas, Tiller can feel like being handed ingredients instead of a meal.

A Freelancer’s Perspective on Both

Running a small architecture practice with irregular project-based income makes PocketSmith’s forecasting genuinely useful: seeing exactly which week a large client payment needs to land before a tax installment is due, mapped against real recurring expenses, turns an anxious guess into a specific date to plan around. Tiller would require building that same forecasting logic manually in a spreadsheet, which is entirely possible for someone comfortable with formulas, but it is additional work PocketSmith does natively.

On the other hand, anyone who already maintains a detailed personal finance spreadsheet, particularly one built over several years with custom categories and formulas specific to their situation, gains more from Tiller feeding fresh transaction data into that existing structure than from abandoning it for a new interface.

What a Trial Month Should Actually Test

Before committing to either tool for a full year, run a genuine one-month trial that mirrors how you actually plan to use it rather than just poking at the interface. For PocketSmith, that means setting up every real recurring bill and paycheck accurately and then actually checking the calendar view before a planned purchase to see whether the forecast changes how you think about the decision. For Tiller, it means spending an actual afternoon customizing the Foundation Template to match at least one category or goal that matters specifically to you, rather than leaving the default template untouched and concluding the tool feels bare.

Most trial periods fail to reveal a tool’s real value specifically because people evaluate the default state rather than the state the tool reaches once genuinely configured for their situation. A calendar with no recurring transactions entered looks unimpressive; a spreadsheet template left at its defaults looks unfinished. Neither is a fair test of what either product actually does once set up properly.

Security and Bank Connection Reliability

Both tools rely on third-party aggregation services to pull transaction data from your actual banks, and connection reliability varies by institution rather than by which budgeting tool you choose. A smaller regional bank or credit union is somewhat more likely to have an occasionally flaky data feed than a major national bank, and this is true regardless of whether the feed is powering PocketSmith’s calendar or Tiller’s spreadsheet. Neither company stores your actual bank login credentials themselves; they use read-only aggregation tokens through providers like Plaid, meaning neither PocketSmith nor Tiller can move money out of your accounts even in a worst-case data breach scenario, only view transaction history.

Tiller’s daily feed timing means a broken connection is usually noticed quickly, since a missing day’s transactions in the spreadsheet is immediately visible the next morning. PocketSmith’s calendar view can mask a temporarily broken connection slightly longer if you are not checking a specific account’s recent transactions closely, since the forecast will simply continue projecting forward using slightly stale data until the connection resumes and catches up. Checking connection status for every linked account roughly once a week, regardless of which tool you use, catches this before it meaningfully throws off a month of tracking or forecasting.

Which One to Pick

Choose PocketSmith if you want to see a specific future date when a financial milestone becomes possible, you are planning around irregular income, or you would rather use a finished tool than build your own system. Choose Tiller if you already think in spreadsheets, want full ownership and exportability of your financial data, or need to feed automated bank data into a highly customized existing budget you have already built.

Both platforms currently offer trial periods, so testing each against one real month of your own transactions before committing to either PocketSmith or Tiller is the most reliable way to see which interface you actually want to open every week.
