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 2020 to 2021, from $2.2M to $10M (+369%).
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 36% · 2018 56% · 2019 59% · 2020 28% · 2021 81% · 2022 36% · 2023 34% · 2024 30% · 2025 26%. Grants only. Government contracts and fees sit inside program revenue.
26% of RTOG FOUNDATION INC’s revenue is contributions — more donation-reliant than the typical peer (7% for the typical peer).

Who funds it, year by year
2022 → 2023: the base held at 1 funder, grant income fell $11k → $8k.
3 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 63% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of RTOG FOUNDATION INC’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
RTOG FOUNDATION INC leans on a few funders — its largest provides 37% of grant income and the top three 92%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund RTOG FOUNDATION INC.
Largest funder’s share by year: 2022 100% · 2023 100% — 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
63% of RTOG FOUNDATION INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $35k that is directly attributable, 100% of it comes from funders outside Pennsylvania, across 1 state.
Funder states come from each funder’s own filing. $60k 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
RTOG FOUNDATION INC holds deeper cash reserves than three-quarters of the 2,969 health nonprofits its size.
