The answer
Holding today's deposit of $0 flat, this fund goes negative in FY2028. Closing the gap takes $34,358 a year more — or, with less price shock, a deposit that grows by $28,716 each year.
One recurrence, applied 10 times: balance = balance × (1 + 0.0%) + deposit − draws. Deposits are today’s figure, held flat. No solver and no goal-seek — the answers below are closed-form, so the same inputs always give the same figures.

Where the two answers come from
the same arithmetic, checkable on paperThe flat answer. The binding year is FY2029 — the year whose cumulative draws are hardest to cover. Through it:
| Draws, FY2028–FY2029 | $70,000 |
| less the opening balance | − $1,284 |
| less the deposits already planned | − $0 |
| Uncovered | $68,716 |
| spread over 2 equal annual additions | $34,358 / yr |
The gradual answer — the one with less price shock.Instead of the same amount every year, the addition grows: $28,716 in year one, $57,432 in year two, and so on. A deposit rising in year t contributes t steps by year T, so the divisor is 1 + 2 + … + 1 = 1rather than 1:
| Uncovered through the binding year FY2028 | $28,716 |
| divided by the triangle number 1 | $28,716 more each year |
This is the recommendation the budget request prints: a gradual annual adjustment so that no year goes negative and there is less price shock. The Town raises a contribution once — it does not reset one. As projects shift, are removed, or reprice, both answers recompute; they cannot go stale.
