Frequently asked questions
What is the difference between a flat rate and a reducing balance rate?+
Under a reducing-balance rate, interest is charged only on the amount you still owe, so it falls as you repay. Under a flat rate, interest is charged on the full original amount for the whole tenure regardless of how much you have already repaid. A flat rate therefore always costs considerably more than the same number expressed as reducing balance — a 14% flat rate over 24 months works out to roughly 24.9% on a reducing-balance basis.
How do I calculate the EMI on a battery loan?+
For a reducing-balance loan the instalment is P x i x (1+i)^n / ((1+i)^n - 1), where P is the amount financed, i is the periodic interest rate and n is the number of instalments. For a flat rate, total interest is principal x rate x years, and the instalment is principal plus that interest divided by the number of instalments. This calculator does both, and also computes the APR once charges are included.
What is APR and why is it higher than the interest rate I was quoted?+
APR is the all-inclusive annualised cost of a loan: interest plus every fee. It is higher than the quoted interest rate whenever charges are involved, because those charges are part of what the credit costs you. A 14% reducing-balance loan with a ₹2,000 processing fee on ₹1,00,000 over 24 months has an APR of about 18.1%. APR is the only number that lets you compare two offers fairly.
Do processing charges count towards the APR if I pay them upfront?+
Yes. Whether a fee is added to the loan or paid separately at the start, you are worse off by that amount, so it forms part of the cost of credit. This calculator treats file and other charges as part of the APR either way. A refundable security deposit is excluded, because it comes back to you.
Can I get a battery loan with daily or weekly repayments?+
Some lenders offer daily or weekly collection, which can suit drivers whose income arrives daily. Check two things before choosing it: whether the collection method carries an extra charge, which should appear inside the APR rather than alongside it, and how a missed day or a slow week is treated.
Is Wingzman the lender?+
No. Wingzman is a Lending Service Provider under the RBI (Digital Lending) Directions, 2025. Loans are granted by Regulated Entities, and every credit decision, rate and charge is theirs. The binding figures are those on the Key Fact Statement issued by the lender named in your loan agreement.
Flat rate and reducing balance are not comparable
This is the single most useful thing the calculator shows. Under a reducing-balance rate, interest is charged only on what you still owe, so it falls as you repay. Under a flat rate, interest is charged on the full original amount for the whole tenure, regardless of how much you have already paid back.
The result is that a flat rate always costs considerably more than the same number expressed as reducing balance. Switch the interest type above with everything else held constant and watch the APR move. If one lender quotes flat and another quotes reducing, you are not comparing like with like until you convert both to APR.
How the APR here is calculated
The APR is the rate at which the money you actually receive equals the present value of everything you pay back. File charges, processing fees and other charges are treated as part of the cost of credit whether they are added to the loan or paid upfront, because in both cases you are worse off by that amount.
- •Down payment reduces the amount financed and is not part of the loan cost
- •Subvention reduces the financed amount, since someone else is contributing it
- •File and other charges count towards APR either way
- •Security deposit is excluded, because it is refundable to you
This mirrors how a lender must present the APR on the Key Fact Statement you are given before accepting a loan. Use this calculator to sanity-check that document, not to replace it — see our sample Key Fact Statement for the full format and what to check on it.
Daily and weekly repayment
Driver income arrives daily, so a daily or weekly collection can be easier to manage than a single monthly instalment. Switch the frequency above to see what the same loan looks like on each basis.
Two things to check with any lender offering this: whether the collection method carries an additional charge, and how a missed day or a slow week is treated. Ask before you need the answer, not after.
An estimate, not an offer
These figures are indicative and for your own planning. They are not a quote, an approval, or an offer of credit.
