Capital Recovery & The True Cost Per Year
Costs the tractor
Enter the capital cost, the interest rate and the asset's life to get the capital recovery factorand the equal annual cost of owning a tractor, polyhouse or pump — the fair fixed cost to set against returns.
Annualize a capital cost
Next: use this annualized figure when comparing machines or deciding rent-vs-buy — it folds the time value of money into one fair yearly number.
CRF assumes a constant interest rate and even payments across the life; salvage value and rising maintenance are not included.

What a big purchase really costs each year
A tractor, polyhouse or pump is bought once but earns its keep over many seasons, so charging its whole cost to a single year tells you nothing useful. The fair way is to spread that lump sum — plus interest on the money tied up in it — evenly across each year of the asset's life. That's exactly what the capital recovery factor does: it converts a one-off capital cost into an equal annual cost, the true fixed cost the asset carries every year, just like a loan repayment.
This tool computes the capital recovery factor, the annualized cost, and shows the capital cost and life behind it. Use the annual figure as the fair fixed cost to set against the returns the asset earns, and to compare investments on the same yearly basis. Pair it with the Machinery Cost, Depreciation and Buy-vs-Hire tools to build a full picture of what your equipment costs.

Frequently Asked Questions
What is the capital recovery factor?+
The capital recovery factor (CRF) is the multiplier that turns a lump capital cost into an equal annual cost over the asset's life, including interest. Multiply your capital cost by the CRF and you get the fixed amount the asset costs you every year — the same idea as a loan repayment, but used to charge an asset's cost fairly across the years it serves.
How is the CRF calculated?+
CRF = i·(1+i)^n ÷ [(1+i)^n − 1], where i is the interest (or discount) rate per year and n is the asset's life in years. The annualized cost is then capital cost × CRF. For example, a ₹6,00,000 tractor at 9% over 10 years has a CRF of about 0.1558, so its annual capital cost is roughly ₹93,500.
Why annualize a capital cost?+
A tractor, polyhouse or pump is bought once but used for years, so charging the whole cost to one season is misleading. The capital recovery factor spreads that lump sum — plus the interest on the money tied up — evenly across each year of its life, giving the fair fixed cost to set against the returns the asset earns each year.
What interest rate should I use?+
Use your cost of capital — the loan rate if you borrowed to buy the asset, or the return you'd otherwise earn on that money if you paid cash. A higher rate raises the annual cost because the capital tied up is worth more elsewhere. Many farm analyses use a rate close to the prevailing agricultural lending rate.
What life should I enter?+
Enter the asset's useful working life in years — how long it will realistically serve before it's worn out or replaced. Tractors and major implements often run 8–15 years, polyhouses and irrigation infrastructure can be longer, pumps shorter. A longer life lowers the annual cost; a shorter, harder-worked life raises it.
How is this different from depreciation?+
Straight-line depreciation just divides the cost by the years and ignores the cost of money tied up in the asset. The capital recovery factor includes interest, so it's the economically correct annual charge — it answers what the asset truly costs you per year, not just how its book value falls.
Should I include salvage value?+
For a precise figure you'd subtract the present value of any salvage at the end of life before applying the CRF, since you get some money back. This tool gives the core capital recovery on the full cost; if salvage is significant, treat the result as a slightly conservative (high) annual cost.
How do I use the annual cost?+
Compare it against what the asset earns or saves you each year. If a polyhouse's annual capital cost is ₹1,20,000 and it lifts your net returns by more than that, it pays. It's also the fixed cost to fold into a machinery cost or buy-vs-hire comparison so every option is judged on the same yearly basis.
Can I use it for any currency?+
Yes — the capital recovery factor is just a ratio from the rate and the life, so it works in any currency. Enter the capital cost in your own currency and the annualized cost comes back in the same units. The maths is identical whether you think in rupees, dollars or anything else.
