Savings and Compound Interest: End-of-Month Guide
A savings tool shows how starting balances plus end-of-month contributions grow. Interest compounds on prior interest, so longer terms accelerate growth. The nominal rate divided by twelve gives the monthly rate. Everything runs in your browser. Results are for information only, not investment advice.
Step by step
- Enter the starting balance, or zero.
- Enter the monthly end-of-month contribution.

Example scenario
Zero start, 1,000 TL monthly at 12 percent nominal: monthly rate 1 percent, about 12,682.50 TL after 12 months. Contributions 12,000 TL, interest 682.50 TL.

Compare with contribution totals: 682.50 TL on 12,000 TL fits 1 percent monthly. Taxes excluded.
