Annuity formula for depositing at the end of each period. Future value, F=A * ((1+i) ^n-1) / iA=deposit per period, $3000 i=interest per period, 10%/2 = 5% = 0.05 per half yearn=number of periods = 12 years = 24 half-years

If the deposit is at the beginning of each period, thenwe can use the above formula, with 25 periods, but skipping the final payment, i. e. F=A * ((1+i) ^ (n+1) - 1) / i-A=3000 * ((1+.1/2) ^ (24+1) - 1) / (.1/2) - 3000=143181.296 - 3000=143181.30 - 3000=140181.30 (to the nearest cent)
