TLDR
After five years of giving under the 10% pledge, I’ve found that the most useful shift in how I think about it has been treating it less as a one-off moral commitment, and more as something that benefits from ongoing management. This post shares three practical ideas that have helped me: (1) doing periodic “affordability reviews” for your pledge, borrowing a concept from mortgage lending, (2) running a simplified monthly close on your personal finances, adapted from management accounting, and (3) treating any donation shortfall as a personal tracking item on my balance sheet. These are approaches I actually use, and I think they can help make long-term giving feel more sustainable. That said, this level of detail won’t suit everyone: some people will find a simpler approach works better for them, and that’s totally fine.
Who this is for
This post is primarily for people who are already donating regularly or have signed a giving pledge and are now navigating the years that follow. Once the initial excitement of committing to give settles down, what remains is something quieter and more procedural, a process that needs managing. Most of the Forum discussion around personal finance and giving that I’ve seen, tends to focus on the decision to pledge in the first place, or on bigger-picture giving philosophy. There’s comparatively less about the ongoing operational practice of actually managing your giving commitment year after year.
That said, if you’re considering pledging, I hope these ideas might help you picture what the ongoing reality looks like, and perhaps make it feel less daunting than it might seem from the outside.
A quick note on scope: this post is deliberately about the mechanics of managing your giving, the tracking, the budgeting, the review process. It doesn’t address the question of where to give, which is a much larger topic that the Forum covers extensively elsewhere. I also want to acknowledge that the specific examples I use reflect my own circumstances (I’ve worked across countries and have a background in management accounting), so some of this may feel more complex than what most people need. The core ideas (periodic review, tracking your commitments, checking your numbers) can be scaled down for simpler situations.
I signed the 10% pledge in March 2021 around my birthday. Five years on, I wanted to share some of what I’ve learned about the practical side of giving. I was partly inspired by this lovely post, in an attempt to enjoy the process of taking ethics seriously.
The affordability review: borrowing from mortgage lending (but not the stressful parts)
I want to borrow one specific idea from mortgage lending: the habit of periodic affordability review. A mortgage lender checks whether you can sustain repayments before approving a loan, and checks again when your circumstances change. That’s where the comparison ends: a giving pledge is a voluntary commitment you’re happy to have made, not a debt you’re working to pay off. But the discipline of regularly asking “does this still fit my life?” seems quite useful to carry across.
From what I can see, most of us only really think about affordability at the point of signing. We rarely revisit it in a structured way when life changes. I’d suggest doing a simple annual review, built around three questions:
Has my income trajectory changed? A new job, a period of reduced hours, or a move to a different country… These all affect what 10% actually means in practice. What felt comfortable last year may need revisiting.
Have my major financial commitments changed? Taking on a mortgage, starting a family, paying off (or taking on) debt… These shift what’s genuinely affordable. It’s worth being honest about this rather than hoping it works itself out.
Am I still comfortable with my overall financial position? Not just “can I technically afford this”, but “does this feel sustainable for another year or two?” A pledge you quietly resent is arguably worse than a pledge you consciously adjust.
On the one hand, I resonate with the desire to donate more if we can, quoting “if it is in our power to prevent something bad from happening, without thereby sacrificing anything of comparable moral importance, then we ought, morally, to do it” by Peter Singer. On the other hand, I think it’s healthy to build in a moment each year where you check whether you could use some flexibility. The goal is to treat your giving as something you manage responsibly and proactively, rather than something you signed up for once and navigate by feel.
A note on tax relief (which can change the maths quite a bit)
This section flags that tax relief exists and matters. It is not tax advice: the specifics vary by jurisdiction and personal circumstance, and you should consult a qualified professional.
One thing I didn’t fully appreciate when I started was how much tax relief can reduce the effective personal cost of giving. In the UK, Gift Aid means that for every £100 a basic-rate taxpayer donates, the charity receives £125 at no additional cost to the donor. Higher-rate taxpayers can additionally reclaim relief through Self Assessment, reducing their personal cost further. In the US, charitable donations may be deductible if you itemise, with the benefit depending on your marginal tax rate. Other jurisdictions have their own rules.
This is worth factoring into your affordability review: the actual cost of maintaining a 10% pledge may be meaningfully less than 10% of your gross income, depending on your tax position. GWWC has a resource on tax-deductible giving that covers multiple countries and seems to be a good starting point.
Separately, it’s worth knowing about Donor-Advised Funds (DAFs), which are available through providers like the Charities Aid Foundation in the UK or Fidelity Charitable in the US. A DAF lets you make a donation, and in some jurisdictions, claim the tax relief, in the year that suits you, while distributing the funds to specific charities over time. This can be useful for managing timing mismatches between when you have the income and when you’re ready to choose where to give. This post provides a helpful comparison for US donors.
As above, this section describes my personal practice. It is not advice on how you should manage your finances.
Organisations go through what’s called a “month-end close”, essentially a process of reconciling the books at the end of each month to make sure the financial records are accurate and complete. It’s how organisations catch errors early, spot trends, and maintain confidence that they understand their financial position.
I’ve been running a simplified personal version of this for a few years now, and I’ve found it surprisingly useful for managing my pledge. It typically takes me about 30 minutes each month once the system is set up, and it covers four areas:
Income and donations. I calculate what I should have donated that month (my income multiplied by my pledge percentage), and compare it to what I actually donated. I then track the running difference over time. If I’ve donated more than required in a given period, I note the surplus; if less, I note the shortfall. Over time this gives me a reasonably clear picture of where I stand against my cumulative target, which I find more useful than trying to keep track of it in my head. One thing worth noting: “income” is less straightforward than it sounds. Are you calculating 10% of gross salary, or net of tax and pension contributions? Including or excluding bonuses and investment income? GWWC has a page about this, and I think the important thing is to decide deliberately and be consistent.
Expenses. I use an app to record non-recurring spending as it happens, categorised by whatever matters to me, e.g. food, travel, or a one-off project like a home renovation. At month end, the app groups these by category so I can compare actual spending against my rough budget. Nothing particularly sophisticated, but it’s enough to catch any drift before it becomes a problem. It also helps me understand my average monthly outgoings, which can be the basis for budgeting future months.
Assets. I tally up what I own, split into two broad buckets: what I can access relatively quickly (cash, easily sellable investments) and what I can’t realistically access in the near term (pensions, deposits, long-term savings). This distinction matters more than people sometimes realise: your emergency fund is only genuinely useful if it’s liquid. If you’ve lived in more than one country, it may be worth separating your assets by geography so you know what’s accessible where. It may also be helpful speaking to a qualified adviser about how pension and asset transfer rules in each jurisdiction may affect you.
Liabilities. Mortgage, student loans, and if you find it useful, any donation shortfall, which I’ll come back to in the next section.
There’s also a useful validation step at the end: the change in your net assets (assets minus liabilities) from one month to the next should roughly equal your savings (income minus expenses), adjusted for any investment gains or losses and foreign exchange movements. If the two figures are meaningfully different, it usually means something has been misrecorded somewhere. It’s a simple sanity check, but I’ve found it catches mistakes I’d otherwise miss.
I should acknowledge that this level of monthly tracking won’t appeal to everyone, and that’s completely fine. If you’re someone who finds detailed financial tracking stressful or anxiety-inducing rather than helpful, a simpler approach, e.g. an annual check-in, may serve you better. The point is to find a level of discipline that makes giving feel more sustainable for you personally, not to turn it into an obligation that crowds out the sense of purpose that motivated it in the first place.
The shortfall tracker: a personal reframing that might help with falling behind
Important caveat: what I describe here is a personal motivational tool. The GWWC pledge is explicitly not a legally binding contract. The “shortfall” I track is not a debt in any legal, financial, or accounting sense. It should not be disclosed as a liability in any formal context, e.g. mortgage applications, or tax filings.
With that caveat in mind, here’s the idea I’ve personally found most useful.
If my actual donations at a given point in time are lower than my target under my pledge, I record that difference as a personal tracking item, a specific amount I’d like to make up in the future. This would have the effect of reducing my net assets, similar to other liabilities. It’s not a liability in the technical accounting sense: there’s no creditor, no legal enforcement, and no consequence for non-payment beyond my own sense of commitment. But I’ve found that treating it as a concrete number I can see and plan around, rather than a vague intention to catch up eventually, creates a kind of gentle accountability that works better for me than guilt.
A related question is whether a shortfall should notionally grow over time to reflect the cost of delay. $1 donated later buys slightly less than $1 donated today, due to inflation, and there's a reasonable argument that the good it could have done in the interim represents a real opportunity cost. You might choose to apply a simple adjustment for inflation to keep your shortfall target honest in real terms, or you might decide the added complexity isn't worth it for a personal tracking tool. I think either approach is defensible. The important thing is that you've thought about it consciously rather than letting the number quietly erode in value without noticing.
On the other hand, if you’ve donated more than your target in a given period, you have a choice. You might treat the surplus as a credit that lets you pause donations temporarily until your cumulative target catches up. Or you might simply be glad that more resources went to good causes and carry on. Either approach seems perfectly reasonable to me, and the important thing is that you’re making a conscious decision rather than losing track.
The reward: looking at what your giving has actually achieved
After the discipline of tracking and reconciling, there’s also a genuinely enjoyable part of the process: stepping back and looking at what your cumulative giving has achieved over time.
Tools like The Life You Can Save’s impact calculator or research like GiveWell’s cost-effective analysis let you translate your donation amounts into tangible outcomes: lives improved, treatments delivered, tonnes of CO₂ averted, etc. The precision of these numbers is obviously approximate, but I find it a useful way to reconnect with the purpose behind the process, particularly during months where the administrative side feels more like a chore.
It’s also worth periodically asking whether your portfolio of recipient charities still reflects your values. After five years, I found it revealing to look at where my money had actually gone and ask whether the pattern matched what I thought I cared about. This turned out to be a useful prompt for an honest conversation with myself about my priorities.
I also pay attention to the financial management and transparency of the charities I support, since I’d like my donations to be used well and stewarded responsibly. Some organisations set a remarkably high bar here. The Against Malaria Foundation, for example, publishes real-time financial accounts, detailed reporting schedules across their legal entities worldwide, and updates on net distributions. They even email donors when their contribution reaches a specific village! Working in nonprofit operations myself, I have a particular appreciation for unrestricted funding and the organisations that steward it well. Supporting the general operating costs of charities is rewarding to me because it helps them extend their financial runway, and allows them to plan further ahead to work towards the mission.
Getting started
You don’t need my exact spreadsheet to try any of this. In fact, I’d encourage you to build your own, tailored to what matters to you. A large language model like Claude or ChatGPT can generate a personalised template if you describe your situation and what you want to track (and if you are happy with the data privacy policies of these models). In my experience, the best personal finance system is one that fits your life rather than someone else’s.
If you’re thinking about pledging rather than already doing it, the post “Scared to Pledge? 5 financial steps for confident giving” may be a good starting point and has more resources on the personal finance side.
For those of us already on the journey, I hope some of these ideas help make the ongoing process feel more manageable, and maybe even a little enjoyable, if you also love spreadsheets or accounting! The pledge is a commitment worth honouring well, and I think honouring it well means managing it with the same care and attention you’d give to any other important long-term commitment in your life.
I’d love to hear how others approach the practical side of ongoing giving. Do you track your giving targets formally? Have you found tools or habits that help? I’m always looking to learn from others and improve my own process.

Peak Andy. Applying discount rates to pledge shortfalls is delightful on so many levels. Thanks for writing this!
