Fundraising Efficiency Ratio Calculator
For a nonprofit, the total raised is only half the story. The other half is what it cost to raise it, and donors, boards, and watchdog groups all ask that second question before they give again. This calculator answers it in the form those groups actually use: the cost to raise each dollar, the efficiency percentage, and the dollars raised per dollar spent.
Enter your total fundraising expenses and total donations raised, pick the fundraising method, and the tool returns all three numbers plus a benchmark comparison for that method. The worked example below uses $25,000 in expenses and $150,000 raised.
Quick Answer
With $25,000 in fundraising expenses and $150,000 raised, the cost is $0.167 per dollar raised, or 16.7%, which is $6.00 raised for every $1 spent and a Very Good Efficiency assessment. That leaves $125,000, or 83.3% of what was raised, for mission work after fundraising costs.
Key takeaways
- Lower is better on this calculator: the efficiency ratio is the cost to raise a dollar, not the dollars raised per dollar.
- The dollars raised per dollar is a separate output. In the worked example it is $6.00, which is the inverse of $0.167.
- Judge a result against its own method. A gala at 40 cents per dollar can be normal while a major-gifts campaign at the same level is not.
- The BBB Wise Giving Alliance ceiling is 35 cents per dollar of related contributions. Treat it as a ceiling, not a target.

What the fundraising efficiency ratio actually measures
The ratio measures fundraising cost, nothing else. It takes the money spent asking for donations and divides it by the donations that asking produced, for the same period. A result of $0.167 means 16.7 cents of every donated dollar went to the cost of soliciting it.
Fundraising Efficiency Ratio = (Total Fundraising Expenses ÷ Total Donations Raised) x 100
Dollar Raised Ratio = Total Donations Raised ÷ Total Fundraising Expenses
That first line is the definition this tool uses, and it is the definition the BBB Wise Giving Alliance uses in Standard 9: spend no more than 35% of related contributions on fundraising. CharityWatch reports the same idea as cost to raise $100, so a $0.167 result here is $16.70 to raise $100 there, inside its $25 or less mark for a highly efficient charity.
The two directions, kept apart
Confusion here is common because the same numbers appear in both directions. Some guides define a fundraising efficiency ratio as donations divided by expenses, so $150,000 divided by $25,000 becomes 6, meaning $6 raised per $1 spent. Here that figure is called the Dollar Raised Ratio, and it is printed alongside the cost figure so neither direction is mistaken for the other. When a source says a good ratio is $3 to $5 raised per $1 spent, it is talking about this inverse figure, which corresponds to a cost of $0.33 down to $0.20 per dollar on this calculator.
Nonprofit donations are not commercial revenue
This is also where the tool differs from a commercial marketing ratio. Our marketing efficiency ratio calculator divides marketing spend by gross profit or revenue from selling something. That page says plainly that MER is not the fundraising efficiency ratio, and it is right: a nonprofit raising donations has no gross profit to divide by, and a business selling products has no donations. Use the marketing tool for campaigns that sell, and this tool for campaigns that ask.
Benchmarks by method, and what counts as good
A single benchmark misleads because methods carry different cost structures. Acquisition mail loses money on the first gift by design and builds a donor file that pays later, while a major gift can cost a few cents per dollar because one conversation closes a large gift. The calculator compares each result with the benchmark for the method selected, using these ranges and midpoints.
| Method | Typical range | Benchmark used |
|---|---|---|
| Overall fundraising | 15 to 25% | $0.20 per dollar |
| Capital campaign / major gifts | 5 to 10% | $0.075 per dollar |
| Grants / foundations | 15 to 25% | $0.20 per dollar |
| Special events | 30 to 50% | $0.40 per dollar |
| Direct mail, renewal | 20 to 25% | $0.225 per dollar |
| Direct mail, acquisition | 100 to 150% | $1.25 per dollar |
| Online / digital fundraising | 5 to 15% | $0.10 per dollar |
| Planned giving | 20 to 30% | $0.25 per dollar |
The performance bands the tool assigns are separate from the method benchmarks, and they apply to the cost figure whatever the method: $0.10 or less is Excellent, $0.20 or less is Very Good, $0.25 or less is Good, $0.35 or less is Average, $0.50 or less is Below Average, and anything above $0.50 is Poor. Read the two together. An events result of $0.40 is Average on the general bands but right on its method benchmark, while a major-gifts result of $0.40 is Poor on both.
The bars show the worked example split: of $150,000 raised, $25,000 went to fundraising costs and $125,000 remained for mission activities before program and administrative spending, which this ratio does not cover.
How to use this calculator
Use one period for both inputs, or the ratio is meaningless. Annual figures give an annual ratio; a single campaign gives a campaign ratio, and the two should never be mixed.
For event costing itself, price the event first with our event cost calculator, then bring that event cost into this tool as the fundraising expense for the event method. For valuing non-cash gifts before they enter the donations figure, our donation value calculator covers that step, and for a commercial campaign that earns a return on spend rather than donations, our return on spend calculator is the right tool.
Worked examples checked against the tool
Every number in this section reproduces exactly when entered into the calculator above.
Example 1: the defaults, overall fundraising
Expenses $25,000 divided by donations $150,000 gives $0.167 per dollar, or 16.7%. The inverse is $6.00 raised per $1 spent, the mission remainder is $125,000 (83.3%), the return on fundraising spend is 500%, and the assessment is Very Good Efficiency. Against the overall benchmark of $0.20, this result sits 3.3 percentage points better.
Example 2: a capital campaign
Expenses $100,000 divided by donations $500,000 gives $0.200 per dollar, or 20.0%, with $5.00 raised per $1 spent and a Very Good Efficiency assessment. That looks strong in general, but against the capital campaign benchmark of $0.075 it sits well above the method level, which is the kind of gap a board should ask about rather than celebrate.
Example 3: an event that loses money
Expenses $1,500 divided by donations $1,000 gives $1.500 per dollar, or 150.0%, with $0.67 raised per $1 spent and a Poor Efficiency assessment. Any result above $1.00 per dollar, or 100%, means the organisation spent more on fundraising than it raised in that period. For an acquisition campaign that can still be a deliberate investment; for a one-off event it is a loss that needs a reason, not a rounding error.
What competing calculators miss
Most single-number tools return one division and stop. They give a cost per dollar with no method benchmark, so a gala and a grant proposal are judged by the same number. They also routinely print only one direction of the ratio, which is how a reader ends up comparing a $6 figure from one site with a $0.17 figure from another as if they were different results. And they rarely show the mission remainder or the return on fundraising spend, which are the two numbers a board actually discusses. This tool prints all three headline outputs, compares the result with its own method benchmark, and states the mission remainder in dollars and percent, so the percentage cannot hide behind itself.
The strengths and limits of this ratio
The ratio is a cost measure, and it should be used as one. It does not measure whether the programs funded were effective, whether donors stayed, or whether a campaign built a base for future years.
What it does well
- Compares fundraising cost across years on a like-for-like basis
- Flags a method whose costs have drifted from its own benchmark
- Gives donors and funders a checkable, auditable figure
- Separates fundraising cost from program and administrative spending
Where it misleads
- Ignores donor retention and lifetime value
- Rewards cutting investment that would pay off in later years
- Skews badly when one very large gift lands in a single period
- Says nothing about program outcomes or impact
New organisations typically run higher ratios, often 35 to 50%, during startup, when there is no donor file to renew and every gift must be acquired. Acquisition is the same story in miniature: a cost above $1.00 per dollar on first gifts can be rational if those donors renew, and ruinous if they do not, which is why this ratio should always be read next to retention figures and multi-year trends rather than alone. One more accounting trap matters: CharityWatch warns that comparing fundraising cost with total income, including patient revenue, investment income, or sales, flatters the ratio, because the denominator then includes money fundraising never produced. Use related contributions only.
Frequently asked questions
On this calculator, a good result is a cost of $0.20 or less per dollar raised, which is $5.00 or more raised per $1 spent and a Very Good Efficiency assessment or better. The BBB Wise Giving Alliance ceiling is $0.35 per dollar of related contributions, and CharityWatch treats $25 or less to raise $100 as highly efficient. What counts as good still depends on method and organisation size, so compare against the method benchmark the tool shows, not a single universal number.
It means the organisation spent more on fundraising than it raised in that period, and the dollar raised ratio falls below $1.00. For donor acquisition this can be a deliberate first-year investment. For a single event or an established renewal program it is a loss that needs explaining.
Yes, if the staff are directly involved in fundraising. Salaries, benefits, and contractor time spent soliciting donations are fundraising expenses. Staff time spent delivering programs is not, even if the same person does both jobs, in which case the time should be split on a reasonable basis.
At least annually, and after every major campaign. Annual figures smooth out single-gift spikes, while campaign figures show which methods are drifting from their benchmarks before another year of spending repeats the pattern.
Yes, many funders look at fundraising efficiency, and the figures behind it come from the same reporting nonprofits already file. Fundraising expenses and contributions are reported on IRS Form 990, with supplemental fundraising detail on Schedule G for organisations above the filing thresholds.
No. It measures fundraising return only, not social outcomes. A campaign can be cheap and fund a weak program, or expensive and fund an excellent one. Read it alongside program results, retention, and reserves, never as a verdict on the mission itself.
Start with retention, because keeping a donor is cheaper than acquiring one. Then shift spend toward lower-cost methods such as digital fundraising where the audience fits, automate routine outreach, and target prospects with data rather than broad mailings. Cutting acquisition entirely improves this year ratio while shrinking next year donor file, so judge the change over two or three years.
Efficiency is the cost per dollar raised. ROI, as shown in the tool detailed analysis, is (donations minus expenses) divided by expenses, times 100. In the worked example the efficiency ratio is 16.7% and the ROI is 500%, because $125,000 of net funds came from $25,000 of fundraising spend. They describe the same result from opposite sides.
Only against similar-sized organisations with similar missions and methods. A national health charity running galas, a local food bank running online appeals, and a university running a capital campaign face different cost structures, and a direct comparison across those groups proves very little.
Usually a strong donor base, major gifts, or corporate partnerships that require little solicitation expense, or a single very large gift or bequest landing in one period. That last case is exactly why multi-year figures matter: one bequest can make a single year look far more efficient than the underlying fundraising operation is.
