Actual outturn as reported after the year closed, not the estimate voted at the start of it.
• Revenue: £4,876,246 • Expenditure: £7,171,997
The slump year: revenue fell by almost a third and the deficit was the largest of the interwar period. A separate January–March 1921 bridging quarter recorded £1,566,748 revenue.
Colonial figures are in sterling; hyphenated years (e.g. 1925-26) are April–March financial years. What counts as 'revenue' changed over time — the railway was included from 1925-26 and excluded again from 1936-37 — so compare neighbouring years with care.
