Karthik Iyer is an independent researcher covering early-stage startup infrastructure costs in India. He has contributed various startup newsletters with a focus on unit economics and cost efficiency for pre-Series A businesses. His analysis draws on publicly available pricing data, merchant community benchmarks, and onboarding documentation across major Indian payment providers.
A bootstrapped consumer app processing Rs. 1.5L/month switched payment gateways to save 0.25% on TDR. The projected annual saving: Rs. 4,500. Twelve months later, a 13% payment failure rate had quietly cost them Rs. 2.9L in unrecovered GMV. The payment gateway had the lower TDR. It also had no smart routing, an Rs. 4,999/year annual maintenance charge buried in the onboarding documentation, and a success rate 10 points below the market leader. The decision that looked like a cost saving had become a significant revenue drain, and the founder had not seen it coming because the pricing page showed only one number.
For Indian startup founders evaluating payment gateways — including the Razorpay payment gateway and its alternatives — that single number is almost always the wrong starting point.
What Founders Get Wrong When Choosing a Payment Gateway?
Mistake 1: Optimizing for TDR While Ignoring AMC
TDR (Transaction Discount Rate) is the percentage deducted from each successful transaction. At 2%, a Rs. 1L/month business pays Rs. 2,000/month in transaction fees. It is the number on every pricing page, and it is the number most founders use to compare payment gateways. The problem is that several payment gateways also charge an Annual Maintenance Charge, ranging from Rs. 3,600 to Rs. 4,999/year, that does not appear in the TDR comparison. At Rs. 4,999/year, AMC adds Rs. 417/month in fixed overhead. For a startup at Rs. 1L/month in GMV, that is a 21% cost increase on top of the stated TDR, applied before a single transaction is processed.
Mistake 2 : Treating Payment Success Rate as a Technical Detail
Payment success rate, the percentage of checkout attempts that complete successfully, is a revenue variable, not a technical one. A payment gateway running at 80% success fails 20 out of every 100 payment attempts. At Rs. 1L/month in GMV, that is Rs. 20,000 per month in unrecovered revenue lost before TDR is calculated. The spread between the lowest and highest success rates among Indian payment gateways is approximately 13 percentage points. At Rs. 2L/month, that gap is worth approximately Rs. 26,000/month in retained revenue, a number that never appears on any pricing page.
Mistake 3 : Conflating International Payment Tools with Domestic Payment Gateways
Several startups shortlist international payment platforms alongside domestic gateways as if they are interchangeable. They are not. A platform designed for receiving USD or EUR from foreign clients does not process domestic Indian UPI transactions, domestic card payments, or net banking flows. Founders who need both international billing and domestic consumer checkout require two separate tools, one for each function.
Mistake 4: Ignoring the Break-Even Math
A payment gateway with 1.75% TDR and Rs. 4,999/year AMC is not cheaper than a 2% payment gateway with zero AMC for businesses processing under Rs. 2.08L/month. The monthly AMC of Rs. 417 is only offset by the 0.25% TDR saving above Rs. 1,66,800/month in GMV. Below that threshold, the zero-AMC option retains more revenue in absolute terms, every single month, regardless of which TDR looks lower on the pricing page.
The TCO Formula: Net Realized Revenue = (GMV x Payment Success Rate) - (GMV x TDR) - Monthly AMC
The table below shows what this looks like in practice across realistic startup GMV tiers, comparing a high-ROI payment gateway profile (2% TDR, zero AMC, 93% success rate) against a low-headline-cost profile (1.75% TDR, Rs. 417/month AMC, 85% success rate):
Monthly GMV |

Payment Gateway B has the lower headline TDR at every row. Payment Gateway A retains more revenue at every row. The gap widens as GMV scales, at Rs. 5L/month, the lower-TDR-with-AMC option costs Rs. 39,167 more per month in unrealized revenue than the zero-AMC, higher-success-rate alternative.
Top 5 Cheapest Payment Gateways for Indian Startups in 2026
1. Razorpay
For most Indian startups processing domestic GMV, The Razorpay payment gateway is best for Indian startups processing domestic GMV from Rs. 50K/month upward, where total cost of ownership matters more than the headline TDR comparison.

The combination of zero annual maintenance charges and a 93%+ payment success rate is not common among Indian payment gateway providers, and it is what makes Razorpay's TCO case. At Rs. 2L/month in GMV, a zero-AMC payment gateway with 93% success retains approximately Rs. 16,917 more per month than a 1.75% TDR payment gateway with Rs. 4,999/year AMC and 85% success, before any other variable is introduced. For a startup founder watching monthly burn, that figure is the relevant comparison, not the headline TDR. The payment gateway covers 100+ payment modes including UPI, domestic cards, net banking, wallets, EMI, and BNPL, with dynamic routing that contributes directly to the success rate benchmark. Subscription billing, payment links, and invoicing infrastructure are included. For startups that grow past Rs. 5L/month in monthly GMV, custom pricing is available through a direct sales conversation, which removes the ceiling on cost competitiveness at scale.
The honest limitations for founders to weigh: the dashboard is feature-dense and has a learning curve for first-time users, support response times can slow during high-volume periods, and international payment processing requires a separate activation process billed at 1% to 3%, not the standard 2% TDR.
Watch out for: International payment activation is not automatic. Startups expecting to bill international customers from day one should initiate the approval process early, it is a separate flow from standard onboarding.
Best for: Razorpay payment gateway is best Indian startups processing domestic GMV from Rs. 50K/month upward, where total cost of ownership matters more than the headline TDR comparison.
2. Instamojo
For pre-revenue and very early-stage startups, Instamojo removes every fixed cost barrier, including AMC, making it the right first payment gateway for founders who are not yet at meaningful GMV.

Instamojo's free plan is genuinely free: no AMC, no setup fee, no minimum volume requirement. For a founder processing Rs. 20,000-30,000/month while testing product-market fit, the elimination of all fixed overhead is the right economic trade-off. The constraint that appears as GMV grows is the approximately 80% payment success rate. At Rs. 1L/month, an 80% success rate means Rs. 20,000/month in GMV that never converts to revenue. At Rs. 2L/month, that unrecovered amount doubles to Rs. 40,000/month, which is Rs. 4.8L/year in GMV simply lost to checkout failure. Beyond the Rs. 50,000-70,000/month mark, the compounding revenue cost of the success rate gap typically outweighs the simplicity of the free plan. International payments are not supported, which is a hard constraint for startups with any cross-border revenue.
Watch out for: The ~80% success rate is a manageable trade-off at under Rs. 30K/month in GMV. Above that threshold, the monthly revenue cost of 20 failed checkouts per 100 attempts grows faster than most founders model when comparing on TDR alone.
Best for: Pre-revenue or very early-stage bootstrapped startups under Rs. 50K/month in GMV where zero fixed cost and fast onboarding take priority over checkout conversion optimization.
3. Zoho Payments
Zoho Payments is the right payment layer for startups already running their operations on the Zoho product suite, and a less compelling choice for everyone else.

The genuine advantage Zoho Payments offers is deep integration with Zoho CRM, Zoho Books, Zoho Subscriptions, and Zoho Invoice. For a SaaS startup or services business that manages its entire revenue workflow inside the Zoho ecosystem, the payment layer becomes part of a unified billing system rather than a separate tool requiring reconciliation. The AMC is bundled into the Zoho subscription plan rather than independently priced, which means the effective cost depends on which Zoho tier the startup is already paying for. The gap in publicly available payment success rate data is a real shortlisting risk, for a startup choosing a payment gateway, the inability to benchmark domestic Indian checkout performance means taking the success rate variable on faith rather than on data. Outside the Zoho stack, there is limited differentiation from dedicated payment gateway providers at equivalent TDR levels.
Watch out for: Zoho Payments' domestic success rate on Indian payment methods (UPI, net banking, domestic cards) is not publicly disclosed. Request this data before committing to it as a primary payment gateway, particularly if checkout conversion is a meaningful growth variable for the business.
Best for: Startups running CRM, invoicing, and subscriptions on the Zoho platform who want payment processing integrated natively into existing Zoho workflows.
4. PhonePe Business
PhonePe Business brings genuine UPI routing strength to the table, making it a relevant option for consumer startups where UPI is the dominant payment mode, with meaningful caveats on the broader payment gateway product.

PhonePe holds a significant share of India's retail UPI volume, and that distribution depth translates into genuine checkout reliability for UPI-mode transactions. For a consumer startup where 60-70% of customers pay via UPI, the routing advantage is operationally meaningful. The picture is less straightforward outside UPI flows: PhonePe's business payment gateway product is still maturing relative to the category leaders on card success rates, EMI coverage, and API documentation depth. AMC terms are not consistently published on the public pricing page, which introduces a cost transparency gap that should be resolved at onboarding before the payment gateway is shortlisted. For startups whose transaction mix goes beyond UPI, particularly those with EMI-heavy or card-heavy checkout profiles, the success rate advantage on UPI does not carry through to the full transaction stack.
Watch out for: Confirm the specific AMC applicable to your merchant tier before onboarding. The public pricing page does not consistently disclose this, and the effective monthly cost depends on terms confirmed during the sign-up process.
Best for: Consumer startups with a UPI-first transaction profile and under Rs. 10,000 average order values, where UPI checkout reliability is the primary conversion concern.
5. Payoneer
Payoneer is not a domestic Indian payment gateway, and understanding that distinction is the most important thing a founder can know before putting it on a shortlist.

Payoneer is a cross-border payment platform built for receiving USD, EUR, GBP, and other currencies from international clients, marketplaces, and platforms. It is widely used by Indian freelancers, agencies, and SaaS companies billing foreign clients. For that specific use case, collecting international revenue, Payoneer is a strong, cost-effective tool with zero AMC and competitive international receipt fees. What it does not do is process domestic Indian consumer payments. There is no UPI integration, no domestic card checkout, no net banking support, and no INR consumer transaction capability. A startup that needs both international client billing and domestic Indian consumer checkout requires Payoneer for the former and a dedicated Indian gateway for the latter. Treating them as alternatives is a category error that leaves one of the two problems unsolved.
Watch out for: Payoneer does not replace a domestic Indian payment gateway. Startups with any domestic Indian consumer revenue stream need a separate gateway for UPI, cards, and net banking, Payoneer cannot process these transactions.
Best for: Indian startups billing international clients in USD, EUR, or GBP, specifically agencies, freelancers, and SaaS businesses with foreign revenue, as a complement to, not a replacement for, a domestic Indian gateway.

The Verdict: Best Payment Gateway TCO for Indian Startups in 2026
Under Rs. 50K/month in GMV: Fixed cost elimination is the priority at this stage. A payment gateway with zero AMC and zero setup fee removes the cost floor entirely, making the monthly payment gateway cost a pure function of transaction volume. The revenue cost of a lower success rate at this GMV tier is typically under Rs. 4,000/month, an acceptable trade-off for pre-revenue or early-traction founders minimizing overhead.
Rs. 50K to Rs. 2L/month: This is the band where the combination of zero AMC and a 93%+ success rate produces the clearest TCO advantage over alternatives. A payment gateway charging Rs. 4,999/year in AMC and running at 85% success loses the cost-effectiveness argument entirely below Rs. 2.08L/month in GMV, regardless of its lower headline TDR. For startups in this range, the monthly retained revenue difference is material and compounds with every billing cycle.
Rs. 2L to Rs. 5L/month: The break-even between a zero-AMC payment gateway and a lower-TDR-with-AMC alternative falls at approximately Rs. 2.08L/month. Above that, the lower-TDR option begins to narrow the gap on the TDR component alone. However, the success rate differential continues to produce a compounding retained revenue advantage on each billing cycle, the 93%+ benchmark is the variable that keeps the TCO case intact well above the break-even point.
Above Rs. 5L/month: Custom pricing becomes available from the leading domestic payment gateway at this volume, negotiated through a direct sales conversation. Above this threshold, the static rate comparisons on public pricing pages become less relevant, the real cost is determined by negotiated terms, not published TDRs.
For international billing: Consider the Razorpay payment gateway's international stack or Payoneer as a complement for cross-border billing.
Frequently Asked Questions
Which payment gateway is cheapest for Indian startups?
On total cost of ownership, TDR, annual maintenance charges, and payment success rate combined, the cheapest gateway for Indian startups processing under Rs. 2L/month in domestic GMV is not necessarily the one with the lowest stated TDR. A zero-AMC gateway with a 93%+ success rate retains more revenue per rupee of GMV than a 1.75% TDR gateway carrying Rs. 4,999/year in AMC and an 85% success rate, for any business processing below approximately Rs. 2.08L/month. Below Rs. 50K/month, a free-plan payment gateway with zero AMC is the most cost-effective option regardless of success rate, since the fixed cost elimination outweighs the success rate gap at minimal volumes.
Does Instamojo charge annual fees?
Instamojo's free plan carries zero annual maintenance charges and zero setup fee. The standard 2% TDR applies per successful transaction. There is no fixed monthly or annual overhead on the free plan, making it genuinely cost-free to maintain at any transaction volume. The trade-off is a payment success rate of approximately 80%, which creates an increasing revenue cost relative to higher-success-rate alternatives as monthly GMV grows above Rs. 50,000-70,000/month.
What is the payment success rate of Razorpay?
Razorpay's reported payment success rate is 93%+, the highest among the major Indian payment gateways reviewed in this comparison. The gateway achieves this through dynamic routing and intelligent retry logic that reroutes transactions to reduce preventable failures. At Rs. 2L/month in GMV, Razorpay's 93%+ success rate retains approximately Rs. 16,000 more per month in recovered revenue than a gateway running at 85% success, before TDR is applied to either figure.
Which payment gateway has zero setup fee and zero AMC in India?
Among the gateways reviewed here, Razorpay and Instamojo both carry zero setup fees and zero annual maintenance charges. Razorpay's zero AMC applies at all GMV tiers with no minimum volume requirement. Instamojo's free plan also carries zero AMC and zero setup fee. The distinction is payment success rate: Razorpay reports 93%+, while Instamojo runs at approximately 80%. For startups above Rs. 50K/month in GMV, that success rate gap produces a monthly revenue cost that exceeds the AMC saving from choosing the lower-performance zero-AMC option.
