Subscription received during 2018 was Rs 1,50,000. Outstanding subscription was Rs 10,000 at the start and Rs 7,000 at the end; subscription in advance was Rs 3,000 at the start and Rs 5,000 at the end. Subscription for the year is:

1. Begin with the cash actually received during the year, Rs 1,50,000. 2. Add the opening advance of Rs 3,000, because that money was collected last year but is income of this year. 3. Add the closing outstanding of Rs 7,000, because that income has been earned this year though not yet received. 4. Subtract the opening outstanding of Rs 10,000, since that cash relates to last year's income. 5. Subtract the closing advance of Rs 5,000, since that belongs to next year. 6. The result is 1,50,000 plus 3,000 plus 7,000 minus 10,000 minus 5,000, which is Rs 1,45,000. _Source: TN HSC Class 12 Accountancy (Samacheer Kalvi, Govt of Tamil Nadu), Unit 2 "Accounts of Not-for-Profit Organisation", Illustration 11_
