Predictable Annual Spikes
Most monthly budgets fail not because of daily chai or dining out, but because of irregular, predictable annual spikes:
1. Diwali & Festive Gifting: ₹25,000 – ₹50,000
2. Vehicle Insurance & Annual Servicing: ₹18,000 – ₹35,000
3. School Admission / Annual Fees: ₹40,000 – ₹1,20,000
4. Health Insurance Premium Renewal: ₹20,000 – ₹45,000
5. Home Maintenance & Festive Travel: ₹30,000 – ₹60,000
The Sinking Fund Solution
Total Annual Spikes = ₹1,80,000 / year.
Divided by 12 = ₹15,000 / month.
By setting aside ₹15,000 every salary day into an annual sinking fund, when the insurance bill arrives in July, you pay it instantly with zero stress.
