The question most church boards ask their lender is how much a church can borrow, and it is the wrong question to start with. A lender will answer it with a ceiling, and a ceiling tells you the most a bank is willing to risk on your congregation. It says nothing about what your ministry can carry for twenty years while still paying staff, funding missions, and absorbing the year when giving dips. The number that matters is the second one, and almost every church building loan that goes badly went badly because the board treated the first number as if it were the second. This post walks through how church lenders actually size a loan, where those rules of thumb come from, and how to turn them into a borrowing number your church can live with.

How church lenders size a loan

The oldest rule in church lending is that total debt should not exceed roughly three times a church’s annual undesignated income. AGFinancial, the financial services organization that lends to Assemblies of God congregations, states it plainly in its published guidance for churches, and the same rule appears in church banking guidance at least as far back as 2008. Undesignated is the key word. It means the general fund giving that arrives every year without strings attached, not building fund gifts, not campaign pledges, not the one-time estate gift that arrived last spring. A church taking in $500,000 a year in undesignated giving is looking at a rough ceiling of about $1.5 million.

The multiple is only the headline. The same AGFinancial guidance, as posted in October 2026, lists the ratios underneath it: annual debt service below 33 percent of general income, debt service plus personnel costs at no more than 65 percent of general income, personnel costs below 45 percent of total income and preferably closer to 33 percent, a loan-to-value ratio of no more than 75 percent, and cash reserves of at least one to three months of fixed operating expenses. Lenders will also ask for at least three years of income statements and balance sheets, and they want to see positive operating margins across those years. None of these ratios is exotic. Together they describe a church that can make its payment in a bad year without cutting a staff position to do it, which is exactly what the lender is trying to confirm.

The 30 percent neighborhood for debt service is not unique to one lender either. Writing in Church Executive in October 2008, Dan Mikes of Bank of the West’s church banking group described the three-times rule as the long-established standard and cautioned churches against committing more than about 30 percent of income to debt service, precisely to leave room for higher rates or lower giving later. He also made the point that campaign pledges are non-recurring by nature, so a church’s debt after the campaign ends should sit near three times general fund giving alone. The specific numbers have shifted a few points over the years and vary from lender to lender, but the shape of the test has been stable for a long time.

Why the ratios matter more than the multiple

Here is where the arithmetic gets interesting. Take that same church with $500,000 in undesignated giving and assume it spends 40 percent of income on personnel, which is $200,000 a year and comfortably inside the 45 percent guideline. Under the 65 percent combined test, debt service and personnel together can reach $325,000, which leaves $125,000 a year for loan payments. At 7 percent over 25 years, $125,000 a year in payments supports a loan of about $1.47 million. That is just under the three-times ceiling, and it is the personnel ratio, not the multiple, that sets the limit.

Now change only the loan term. The same $125,000 a year at 7 percent over 20 years supports only about $1.34 million, because each payment has to retire principal faster. A church that also carries a heavier staff, say 45 percent of income in personnel, has $100,000 a year of room under the combined test instead of $125,000, and its borrowing capacity drops by roughly a fifth before anyone has looked at the building. These are illustrative calculations rather than a quote, and your lender will run its own, but they show something boards rarely hear: the size of your loan is decided as much by your staff budget and your amortization schedule as by your giving.

It also works the other way. A full $1.5 million at 7 percent over 25 years costs about $127,000 a year, roughly 25 percent of that church’s undesignated income. At 8 percent over 20 years the same loan costs about $151,000 a year, just over 30 percent. The loan amount did not move. The rate and term moved the payment from comfortable to the edge of what most lenders will approve, which is why a three-times number quoted to you before anyone has priced the loan is a starting point and nothing more.

The risks that do not show up on the approval letter

Not every church mortgage is fixed for its full life. AGFinancial, for example, offers terms up to 25 years with rate adjustment periods of one, three, five, or seven years, and it advises churches against the longest terms because of the higher total interest cost. Adjustable periods are normal in commercial lending, and they are not a trap, but they deserve their own line in your planning. Suppose that $1.5 million loan starts at 7 percent and resets after five years to 8.5 percent. The remaining balance of about $1.37 million, spread over the remaining 20 years, now costs roughly $142,000 a year instead of $127,000, an increase of about $15,000 a year that has to come from somewhere in the general budget.

Giving is the other variable, and it moves too. If undesignated giving falls 10 percent, from $500,000 to $450,000, the original $127,000 payment rises from about 25 percent of income to about 28 percent. That is still inside most lenders’ limits, which is the point of the cushion. A church that borrowed right up to 33 percent on the strength of a strong year has no such cushion, and the first soft year forces a choice between the mortgage, the staff, and the missions budget. The rule of thumb that keeps debt service near 25 percent rather than 33 is really a rule about surviving a bad year without making that choice.

Construction loans add a third wrinkle, which is that the payment changes shape partway through. During construction, a typical church construction loan bills interest only on the amount drawn so far, and then converts to a permanent loan with regular principal and interest payments when the building is finished. On a fully drawn $1.5 million at 7 percent, the interest-only bill reaches about $8,750 a month near the end of construction. The permanent payment of about $10,600 a month arrives right after, usually in the same season the church is also absorbing higher utility bills, more custodial hours, and the furniture and technology costs that never seem to make it into the first budget. We walked through those costs in detail when we wrote about what the building will actually cost, and every one of them competes with the loan payment for the same dollars.

Where churches actually stand on debt

It helps to know that borrowing has become less common, not more. In Christian Standard’s annual church survey, an average of 60 percent of responding churches reported carrying some debt from 2019 through 2021, and that share fell to an average of 45 percent across 2023 to 2025. For the churches reporting, the overall debt load was about 1.9 times annual giving in 2023 and about 1.4 times in 2025, according to Kent Fillinger’s August 2026 review of the survey. The survey reflects the churches that responded to it rather than every congregation in the country, so treat it as a direction rather than a census. The direction is clear enough: the churches in that survey are borrowing less relative to their giving than they were two years ago, and nowhere near the three-times ceiling.

That matters for how you hear a lender’s approval. If a bank tells you that your church qualifies for three times its undesignated income, it is telling you what it will lend, and that is roughly double the average debt load of the churches in that survey. Sometimes borrowing at the ceiling is the right call, particularly when the alternative is renting a school gym for another five years while construction costs keep climbing. But it should be a decision the board makes deliberately, with a clear picture of the payment in a bad year, rather than a number the board accepts because the lender offered it.

Setting the number your church can carry

The practical sequence is simpler than the ratios make it sound. Start with your last three years of undesignated income and use the lowest of the three, not the average and certainly not the best. Subtract your current personnel cost and any existing debt service from 65 percent of that figure, and what remains is the annual payment you can afford under the most common lender test. Then price that payment at a rate a point or so above today’s quote, over the term you actually intend to use, and you have a loan amount that survives both a rate reset and a soft year. That number, not the three-times multiple, is the one to bring into a conversation about project scope.

Once you have it, the rest of the project budget has to be built around it. Cash on hand, campaign receipts you can count on, and the loan together set the total project budget, and the building has to fit inside that total rather than the other way around. If the building the congregation wants does not fit, the answer is usually not a bigger loan. It is a smaller first phase, a phased master plan that lets the campus grow as giving grows, or a scope decision made before design rather than during bidding. Our approach to master planning for growth is built around that idea: design the whole campus, build the part you can carry, and leave the next phase ready for when the church is.

There is a fair counter-argument to all of this caution. Some churches wait so long to be comfortable that the cost of waiting overtakes the cost of borrowing, and a congregation that has outgrown its building is losing people every month it stays there. Debt is a tool, and a church that borrows a responsible amount to build a space its ministry genuinely needs is often making a better decision than one that saves for a decade and builds something too small by the time it opens. The goal is not to avoid debt. It is to borrow an amount you chose, on terms you understand, with a cushion you can see.

We have worked alongside hundreds of congregations through this exact conversation, and the projects that go well almost always settle the borrowing number before the first sketch, not after the bids come in. That is why we start financial conversations early, test the design against the budget at every phase, and help boards see the payment the building will create before they commit to it. If your church is weighing a building project and you want a partner who will be straight with you about what it will cost and what you can carry, we would be glad to talk it through with you.
