The honest comparison has three parts, and Hindi loses two of them.
A new script, though a phonetic and regular one. Sound distinctions English does not make — the aspirated pairs and the retroflex series. Verb-final word order, which requires rebuilding the way you compose a sentence. And almost no shared vocabulary, where Spanish hands an English speaker thousands of words for free.
Verb conjugation is far more regular. There is no ser/estar problem. There are no articles at all. Spelling matches pronunciation, which Spanish also manages but English speakers still find a relief. And there are two genders rather than the three of German or the irregularity of French.
Published guideline ranges put Spanish at roughly a quarter of the hours Hindi needs for an English speaker. That ratio is a rough institutional average, not a promise, and it shifts substantially with your first language and — more than anything — with how much of your time is spent speaking rather than reading.
Reading an answer is one thing; being corrected while you say it is another. EkGuru tutors teach one to one from $6 a lesson, and most offer a trial.
