The program described on its FY2024 Form 990. Program spending in total: $400,558.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $4.1M to $7.0M (+70%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 28% · 2018 14% · 2019 15% · 2020 18% · 2021 11% · 2022 9% · 2023 36% · 2024 58%. Grants only. Government contracts and fees sit inside program revenue.
98% of SUMTER MUSEUM’s revenue is contributions — more reliant on donations than three-quarters of its peers (63% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base held at 3 funders, grant income rose $40k → $717k.
3 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 7% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $569k from one payer (the payer shares this organization's board, largest Sumter County Museum Foundation). These are real filings, and they are not money SUMTER MUSEUM raised.
From the IRS filings of SUMTER MUSEUM’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
SUMTER MUSEUM leans on a few funders — its largest provides 92% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2017 97% · 2018 98% · 2019 94% · 2020 88% · 2021 96% · 2022 89% · 2023 98% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
100% of SUMTER MUSEUM's grant income comes from South Carolina funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $226k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
SUMTER MUSEUM runs a healthier operating margin than three-quarters of the 5,127 arts & culture nonprofits its size.
