How to use this result
Recurring savings products are contribution-timing products as much as interest-rate products. When you deposit each month, the earlier installments earn longer than the later ones.
This tool gives a first-pass estimate of maturity value and accumulated interest, helping compare scenarios before checking a specific bank product or campaign conditions.
Real installment savings outcomes depend on exact accrual rules, taxation, preferential conditions, and whether deposits are truly fixed or flexible.
Examples
Starter savings plan

Common questions
Q.Why is the interest smaller than a deposit of the same total amount?
Because recurring savings principal arrives gradually over time rather than being invested in full from day one.
Q.Is this fixed-installment or free-installment?
It is a simplified recurring monthly savings estimate, not a full product-rule simulator.
Q.Can I use this for official subscription decisions?
Use it for comparison first, then verify the exact bank product terms before enrolling.
