Policy Stack vs. Excel for Infinite Banking Tracking — Which Is Better?

If you track your Infinite Banking policies in a spreadsheet, you are in good company — most IBC practitioners do. Excel and Google Sheets are free, familiar, and flexible enough to track just about anything. For years, spreadsheets have been the default IBC tracking tool because there was not a real alternative. You built your own tracker, entered data from annual statements, and made it work.

This page is for the moment when “making it work” starts to feel like more effort than it is worth. Maybe you have taken a second policy loan and you are not sure your interest accrual formulas are right. Maybe you added a third policy and the tabs are getting unwieldy. Maybe you want to calculate capital velocity and realized there is no template for that. Or maybe you just want to stop spending your Saturday manually entering numbers from a PDF.

This is an honest comparison of tracking IBC policies in Excel vs. using Policy Stack — what each approach does well, where each falls short, and how to know when it is time to switch.

This comparison applies whether you practice Infinite Banking (IBC), Bank on Yourself, or any variation of using whole life insurance as a personal banking system — the underlying policy mechanics and tracking needs are the same.

The Quick Verdict

Side-by-Side Comparison

What Excel Does Well

Give credit where it is due — spreadsheets have real advantages.

Free and universally available. Google Sheets costs nothing. Excel comes with Microsoft 365 or works as a free web version. There is zero financial barrier to entry.

Fully customizable.You can track exactly what you want in exactly the format you want. No one else's opinion about what matters — your spreadsheet, your rules.

Familiar. You already know how to use it. No onboarding, no tutorials, no new interface to learn.

Total data control. Your data lives on your device or your Google Drive. No third-party platform involved.

Works offline. Excel desktop runs without an internet connection.

For someone with a single whole life policy, a once-a-year premium payment, no policy loans, and no need for advanced analytics — a spreadsheet is genuinely the right tool. Do not let anyone tell you otherwise.

Where Excel Breaks Down for IBC

The limitations are not about Excel being bad. They are about IBC mechanics being complex in ways that spreadsheets were not designed to handle.

Policy Loan Interest Accrual

This is the single biggest gap. When you take a policy loan, interest accrues on the outstanding balance. That interest typically capitalizes — meaning it gets added to your loan balance, and then you are paying interest on the interest. The rate and method vary by carrier.

But here is the part that matters for tracking: some carriers use direct recognition (DR), which reduces the dividend crediting on the portion of cash value backing your loan. Others use non-direct recognition (NDR), which continues crediting dividends on your full cash value regardless of outstanding loans. This distinction significantly affects the real cost of borrowing and your net cash value position.

Excel does not know any of this. To track it correctly, you need to build custom formulas that model your specific carrier's loan interest mechanics, your dividend crediting method, and the interaction between the two. Most people either skip this entirely (which means their tracker is wrong) or oversimplify it (which means their tracker is less wrong, but still wrong).

Here is what that looks like in practice. Say you took a $75,000 policy loan at 5% from a direct recognition carrier. After one year, the interest capitalizes — your balance is now $78,750. But because your carrier uses direct recognition, your dividend crediting on that $75,000 of cash value was also reduced, say from 5.5% to 4%. Your spreadsheet shows the loan balance (if you built the accrual formula correctly). But does it also adjust your expected dividend income to reflect the DR reduction? Does it recalculate your net cost of borrowing — the loan interest rate minus the lower dividend credit? Does it update your loan-to-value ratio using the new capitalized balance? For most IBC spreadsheets, the answer to all three is no.

The Second Policy Problem

One policy in a tab is clean. Two policies means two tabs and a summary sheet. Three policies means you need portfolio-level aggregation — total cash value across all policies, total outstanding loans, net available borrowing capacity, combined premium schedules.

By the time you are managing a family banking system with five or more policies across different carriers, your spreadsheet has become a custom application that you are responsible for maintaining. Every new policy means new tabs, new formulas, and new opportunities for errors.

And the questions get harder: What is your total available borrowing capacity across all policies right now? Which policy should you borrow from next — the one with the lowest LTV or the one with the best loan interest rate? What is your combined portfolio dividend income this year vs. last year? If you are adding a new policy for your child, how does that change the portfolio-level projections? Each of these questions is answerable in Excel — but each one requires a new formula, a new summary cell, and a new thing that can break.

Capital Velocity

Capital velocity — measuring how efficiently you cycle capital through your banking system — is one of the most important metrics for active IBC practitioners. There is no Excel template on the internet that calculates it. You are either deriving the formula yourself and building custom cells, or you are not tracking it at all.

For a deeper explanation of capital velocity and how to track it, see our complete guide to tracking capital velocity and policy loans.

Debt Sequencing and Income Stacking

These are operational IBC tools — using policy loans strategically to eliminate external debt in a structured order, and projecting future income streams from your banking system. Excel cannot do either without building what amounts to a standalone application inside a spreadsheet. Most people do not attempt it.

Version Control

Which spreadsheet is the current one? The one on your laptop? The copy on your spouse's computer? The version you emailed to your practitioner last quarter? The one your son downloaded to his tablet?

Google Sheets solves this with real-time collaboration, but it creates a different problem: no easy way to give different people different access levels. Your spouse might need full access. Your practitioner might need read-only. Your adult children might need visibility into the family banking system without the ability to change anything.

Manual Data Entry and Error Risk

Every year, you sit down with your annual statement — a PDF or a paper document — and manually type numbers into cells. Cash value, death benefit, dividend amount, loan balance, premium paid. For every policy. From every carrier.

One transposed digit and your cash value growth chart is quietly wrong for the next twelve months. One formula referencing the wrong cell and your net worth calculation is off. The error does not announce itself. It just sits there until you happen to notice that something does not add up.

The compounding effect is what makes this dangerous for IBC tracking specifically. If you mistype your year-three cash value, every growth rate calculation from year three forward is wrong. Your performance-vs-illustration comparison is off. Your projected break-even date shifts. Your LTV ratio is based on the wrong denominator. One bad number does not just affect one cell — it cascades through every derived metric in the spreadsheet. And because most people only enter data once a year, you might not catch it until the next annual statement arrives and the numbers clearly do not reconcile.

No Alerts

Excel does not remind you that your PUA window closes next month. It does not notify you that your premium is due. It does not flag that your loan-to-value ratio is approaching the point where your carrier might contact you. It tracks data — it does not watch it for you.

When to Switch from Excel to Policy Stack

There is no rule that says you have to switch. Some people genuinely prefer spreadsheets and are willing to do the work. But here are the signals that usually mean it is time:

This page was created by the Policy Stack team. We genuinely respect the spreadsheet approach — most of our users started there, and we have gone out of our way to be honest about when Excel is still the right choice. We have also been specific about where it falls short, because those gaps are exactly why we built Policy Stack.
