Is it better to start an RD with a small amount and increase it later?

I've been thinking of starting an RD but I'm confused about how much I should commit every month.

I can probably manage ₹10k a month, but some months are already pretty packed with expenses so I'm thinking if it's smarter to start with ₹5k and then increase my savings later instead of putting too much pressure on my monthly budget.

I'm looking at DBS for the RD right now since I already use it but haven't decided my RD amount yet.

For people who've done RDs, what did you guys do? I should start with a smaller amount and increase savings later, or just commit to a higher amount from the beginning?
